HPMA User Guide Architecture Overview The HP Medical Archive architecture provides a secure, reliable, and high performance solution for the storage and distribution of very high volumes of fixed content health care data within a data center and optionally a disaster recovery (DR) site. The term “grid computing” is inspired by the success of the interconnection of the electric power and communication network infrastructure in the late 1800s and early 1900s.
Getting Started Role of the Network Management System (NMS) The Network Management System (NMS) performs two primary functions for HP Medical Archive deployments: • It is a monitoring system that notifies administrators of problems when the status of key hardware or software changes. • It is a browser-based interface making the system easily available to multiple users for: • Reporting status information about the grid’s hardware and software so you can monitor and resolve grid issues.
HPMA User Guide Services A service is a software module providing a set of capabilities to the HP Medical Archive system. They are discussed in detail in Chapter 5. Each service consists of components that deliver a particular capability. Each node of the grid has a predefined set of services that it hosts. Services are typically identified by a three letter acronym. Components A component within a service delivers a particular capability.
Getting Started • Configuration—to set or change service settings or alarm monitoring conditions. Consult the specific service descriptions in Chapter 5 for details of the exact information and Chapter 6 for settings available. Software Requirements Accessing the NMS requires access to a web browser with grid access to a well-known address (defined by your system administrator). At this time, the only supported browser is: • Microsoft Internet Explorer v6.

HPMA User Guide Frames The NMS interface is divided into three key sections or frames: • Header • Navigation Tree • Content Frame Every “page” of the NMS interface contains these three frames. Header Content Frame Navigation Tree Figure 6: NMS Interface—Frames Header The Header frame of the NMS interface contains high-level grid status information.
Interface Components top left serves as a button to access the HP Medical Archive Management Interface version information. Version Information (click logo) System Status Indicator Refresh Time Account Management Button Logout Button Figure 7: NMS Interface—Header Frame Refresh Time Information presented in the NMS interface is time-sensitive. Since the interface is delivered as HTML “pages”, the content shown is static.
HPMA User Guide System Status Indicator The System Status icon indicates the highest level of alarm within the grid. If there are no alarms in the system, the icon displays a normal status (green) as seen in Figure 7 on page 13. Select the icon to see the Grid Map X Alarms X Main page listing all current alarm states that are not “normal”. See “Alarm Levels and Indicators” on page 28 for a description of the range of alarm indicators. Chapter 3 covers alarms in detail.
Interface Components Navigation Tree The Navigation Tree on the left side of the NMS interface displays a tree structure of the grid: the sites, cabinets, nodes, services, and components. This frame provides quick access to any element of the grid. Naming Conventions The names that appear in the Navigation Tree follow the following convention: • Locations: • Site A—The primary site for the HP Medical Archive. • Site B—An optional Disaster Recovery (DR) site.
HPMA User Guide Status Indicators The icon beside each location, cabinet, node, and service reflects the overall status of that part of the grid. (Components do not include a status indicator; they retain their normal icon and color.) If there are no alarms, the icon appears in the normal (green) state. If there is an alarm, the icon reflects the most severe alarm currently active on that branch of the tree (see Table 3 on page 29).
Interface Components Page Selectors Some tabs organize information into “pages”. If so, a page selector appears below the selected tab. Select the page name to access that view. Figure 9: NMS Interface—Page Selectors The currently selected page is shown in blue, alternate page options are in black. Property Information (Overview) The Overview tab provides a list of service and component attributes with their values and (if notification is active) their current status.
HPMA User Guide Figure 10: Sample Overview Page Text Color The display of attribute values normally appears black, indicating the service is running normally (reporting to the NMS). If the text appears blue, the service is in an unknown state (not reporting to the NMS) and the attribute values shown are the last known values. In cases where a service is gracefully removed from the grid (offline) the last known attribute values appear in gray italics.
Interface Components Alarms The Alarms tab provides information to trace the source of an alarm and to review an alarm’s history. This tab offers two pages of information. • The Main page displays a table of the attributes actively being monitored, showing their current state. Each row represents a monitored attribute and the color represents the alarm state. The table includes the attribute code, the description, and the alarm time of faults.
HPMA User Guide Some configuration items are not accessible to the Admin account. These can only be changed using the Vendor account. • The Main page form allows you to change the state, label, and notes related to an attribute. WARNING Changing configuration settings requires careful and deliberate planning. Some configurable elements can affect the state of your live system. Only experienced administrators should alter the device and component configuration settings.
Interface Components Navigating Locations and Nodes Once you have logged on to the NMS, the first displayed content is a Scalable Vector Graphic (SVG) indicating two sites. Icons indicate the actual installation of Site A and Site B. As you navigate to a site, the map shows a set of cabinets (the possible maximum of eight); again, icons above the cabinets indicate the actual installation of your grid.
HPMA User Guide Figure 12: NMS Interface—Sample Site Map of Cabinets Selecting a cabinet displays the map with node icons positioned where the hardware is physically located in a fully populated cabinet. The node icons appear beside the nodes that are installed in your grid. The icon reflects the alarm status of each node. The names are defined by the software as described in “Naming Conventions” on page 15.
Interface Components Figure 14: NMS Interface—Sample Server Map of Services As with locations, cabinets, and nodes, you can select a service to reveal status information in the Content frame. The service/component content is more detailed. The grid map, locations, and grid nodes content displays only the Overview tab with its illustrative map. The Content frame for services and components displays the four tabs: Overview, Alarms, Reports, and Configuration discussed in “Tabs” on page 16.

HPMA User Guide System Status Overview The Network Management System provides useful day-to-day information on the status of your grid. When a component of your grid is not performing within expectations however, the NMS becomes a critical assessment tool. Alarm indicators draw immediate attention to grid issues. The NMS uses color-coding and icons for easy identification of alarm locations and levels.
Alarms When an alarm condition is found to be true, that level is checked against the current alarm level for the attribute. If there is no change, then no further action is taken.
HPMA User Guide For information on how to customize the alarm notification settings, see “Alarm Configuration” on page 153. CAUTION Alarm settings are enabled as part of your installation. Changes to alarm settings should not be made for simple convenience; this may conceal underlying problems that should be resolved. If you find an alarm is persistent, discuss the situation with HP technical support before making changes.
Alarms NMS interface. Each alarm level has an associated color and icon. The NMS alarms levels (from lowest to highest) are: Table 3: Alarm Levels and Indicators Icon Color Level Meaning Green Normal All functions are working normally. Yellow Warning An unusual condition exists that does not affect normal operation; most likely related to a component being in a standby state.
HPMA User Guide Figure 16: Sample Alarm Indicator Propagation Alarms Tab Under the Alarms tab of each service or component, colors highlight critical alarm information (Figure 17). By default, the table rows are green to indicate a normal status. If the status of an attribute changes, an alarm row for that attribute changes to the appropriate color (Table 3 on page 29).
Alarms Each row provides detailed information about the alarm (see Table 4 on page 31 for details). More detailed information about each attribute’s code, value, and definition can be found in Chapter 7, “Troubleshooting Alarms” on page 171. Once the alarm is resolved, the alarm returns to the green status to indicate that the attribute has returned to a normal state. You can access and view alarm status at both the service and the component levels.
HPMA User Guide Table 4: Alarm Table Headings (cont.) Heading Definition CId “Cell ID”, a secondary identifier used when a monitored attribute is a cell in a table, such as the Status attribute of the SSM X Volumes component (VMST). The CId indicates the corresponding row in the attribute table. Node ID Unique number identifying the service within the grid. This number is assigned at installation.
Alarms queries provide data based on your specified time and date requirements. For more information on performing queries, see page 39. The generated data displays in a table with the same headings shown on the Main page (see Table 4 on page 31). This data is listed sequentially based on the time of an alarm’s change in state. The most recent change is listed first.
HPMA User Guide These queries are a powerful grid diagnostic tool, enabling you to identify alarm patterns and service issues. Regularly reviewing alarm patterns can resolve minor issues before they impact grid functionality. At the very least, reviewing the alarm history gives an overview of how the system is functioning and may help to prevent future alarms. Alarm Handling The NMS is a critical tool for responding to system alarms.
Alarms the row in the table highlighted in the alarm color. Note down the following information: • Attribute Code—the four-letter identifier for the alarm type • Description—the message explaining the alarm 2. Identify the Component and Attribute a. Using the Description from step 1, determine if the alarm is associated with a specific component. Select the component to view its Alarms X Main page to find the alarm. b.

HPMA User Guide Introduction to Reporting Reports are a powerful system analysis and troubleshooting tool. The NMS can generate reports at both the service and the component level, although some individual attributes do not have reportable events. These reports provide an overview of how a system attribute is functioning over a selected period of time. By viewing a report, you can quickly ascertain if the attribute has any issues. Reports are also valuable to track the data flow on the grid.
Reports Accessing Reports Reports are accessed in one of two ways: • Immediate reports are accessed by clicking the chart icon on the Overview tab for the service or component. • Quick and Customized reports are accessed from a form on the Reports tab under either the Chart page or the Text page. Under the Reports tab, each service and component has select attributes for which reports can be generated. Individual service details in Chapter 5 indicate whether attributes are reportable.
HPMA User Guide To generate an immediate report: 1. Navigate to the service or component you want to report on. The item’s Overview page appears. 2. Scroll to the attribute you want to chart. If reports can be generated for the attribute, the appropriate report button is available at the far right of the attribute’s row. 3. Click on the report button. The Reports page appears and the requested chart is displayed. The report displays the attribute’s data over the past hour, a preset time span.
Reports 3. Optionally deselect the Vertical Scaling check box to force the Yaxis to start at zero. This option is selected by default, allowing the Y-axis to cover a range that best fits the data. —or— Optionally select the Text page to obtain a text format report. 4. Use the Attribute pull-down menu to select the attribute to report. 5. Select the Quick Query button for the desired duration of the report. The report appears after a few moments.
HPMA User Guide 5. In the Custom Query panel, enter the Start Date and End Date for your report. Use the format YYYY/MM/DD HH:MM:SS for both entries. 6. Select the Custom Query button to generate and display the report. The report appears after a few moments. CAUTION Allow several minutes for charts to appear. Although the Content frame may update fairly quickly, charts can take several minutes to tabulate and form the image. Do not initiate another report request until the current one has completed.
Reports Interpreting Lines and Shading Charts use color and shading to convey specific information about the graph. Table 6: Chart Colors and Shading Sample Meaning Reported attribute values are plotted using dark green lines. Light green shading around dark green lines indicates that the actual values in that time range vary and have been “binned” together for faster plotting. The range in light green indicates the maximum and minimum values within the “bin”.
HPMA User Guide Bar Graph Bar (area) graphs are similar to level graphs but include a light brown shading below the line. These are used to plot the values of an attribute that has a “quantity” value (such as Service Load, a percentage). The changes in the value are plotted in “bins” at regular intervals over time. State Graph State graphs are similar to level graphs but the transition is discontinuous; that is, the value jumps from one state (value) to another.
Reports Figure 24: Sample Text Report The Date column lists the local date and time of attribute reports. The Value column displays the attribute’s value for each report. This detailed breakdown of data can result in very long tables. Text reports are therefore better suited to shorter, more specific time spans. Text reports support some attributes—such as changes to text attributes—that are not available in chart form.
HPMA User Guide When you are done, use your operating system’s window close button to close these chart windows. Printing Charts and Reports Reports of any type can be printed—as can any other page of the NMS interface—by using the print function of your browser. Using Microsoft® Internet Explorer: 1. Create the desired report (or other content page). 2. Right-click in the Content frame to access the context menu. Note that where you right-click determines the context menu you get.
Reports Print Options When printing a chart frame, there are two possible outcomes: • Printing from the frame context menu; printing only the selected frame yields a page with: • Content frame heading (service, component, and icon) • The chart itself with its title • Chart window button • Printing from the image context menu drops the Content frame heading and chart window button, yielding only the chart itself along with its title.

HPMA User Guide ADC—Administrative Domain Controller The Administrative Domain Controller (ADC) authenticates the grid nodes and their connections with each other. For two nodes to connect, the ADC must have certificates for both. The ADC maintains the certificates and synchronizes this information with the other ADCs in the grid. In general, all system nodes maintain a connection to at least one ADC.

Only retained service connections can report “Reconnecting” when the connection is lost.
Services and Components CLB—Connection Load Balancer The Connection Load Balancer (CLB) directs incoming content to the most optimal storage service based on a variety of criteria. The CLB ranks nodes based on several factors such as availability, and system load. When the most optimal node has been chosen, the CLB establishes an outgoing connection and forwards the traffic to the chosen node. The CLB serves as a connection pipeline between the remote entity and an LDR for DICOM.

Configuration Only the Storage component offers configurable settings.Storage This component provides check boxes to reset event counters. This can be used to clear alarm conditions. Table 63: FSG X Storage Component Configuration Settings Prompt Type Description Reset Retrieve from Grid Failure Count Check box When selected and applied, the counter attribute for “Files Retrieved from Grid - Failed” is reset to zero. This clears the “FRGF” alarm.
HPMA User Guide LDR Configuration The Local Distribution Router (LDR) supports the standard service settings to change the labeling of the service and add notations. It also offers settings to control the state of the storage and protocol components. The full set of configurable settings is shown below.
Configuration Storage This component provides data on the object storage space and the objects processed. The Storage component tracks the total amount of object storage space being used and the space available. The configuration settings allow you to set the active state of the storage component, force the storage to read-only on restart, and reset the “OCOR” alarm.
HPMA User Guide DICOM DICOM is optional on the HPMA. The configuration settings for the LDR X DICOM component allow you to set the active state of the protocol component, select whether or not to enable the protocol on service restarts, and reset transaction counters to clear alarms. The LDR advertises two ports to the grid, one for query and retrieve operations and one for ingest. When the DICOM component is in “Online” state, both ports are advertised.
Configuration HTTP The configuration settings for the LDR X HTTP component allow you to set the basic state of the protocol component, select whether or not to enable the protocol on service restarts, and reset transaction counters to clear alarms.
HPMA User Guide NMS Configuration The Network Management System supports the standard service settings to change the labeling of the service and add notations, see Table 60 on page 158. NMS Components In addition to the standard service settings, the NMS also supports the following components: • Database • Connectivity There are no configurable settings offered for these components.
Configuration Events The Events component provides counters for a variety of errors. The configuration page enables you to reset the counter to zero (0) for any selected event types. Table 68: SSM X Events Component Configuration Settings Prompt Type Description Description Text Identifies the event being reported. (Display only; cannot be configured.) Count Text Indicates the current counter value for the event type. (Display only; cannot be configured.
HPMA User Guide Network The Network component of the SSM service is distinct from other services. The SSM X Network X Configuration X Main page provides the ability to reset the error counters. Table 69: SSM X Network Component Configuration Settings Prompt Clear Error Counts Type Description Check box Resets all network component error and fault counters. This clears the “FERR” alarm.

HPMA User Guide Overview Troubleshooting consists primarily of how to respond to various alarms. This chapter provides a detailed table with the alarm codes and the suggested response. If a serious issue arises to which no answer is provided in this chapter, contact HP technical support directly. Alarm Reference Table The NMS comes with a series of pre-configured alarms when the system is implemented. Each alarm can be configured to suit your grid management needs.
Troubleshooting Alarms Attr. Code Description Recommended Action AMQS Audit Message Queue Size; a count of audit messages waiting in the queue to be committed to the database. Alarms are based on the queue being over a specified threshold. During heavy loads the queue can go over 10,000 or even 50,000, but at that level it should be closely monitored. Check the load on the system—if there have been a significant number of transactions this may be normal and will resolve itself over time.
HPMA User Guide Attr. Code Description Recommended Action CIAF Count of Incoming Associations Failed; the number of DICOM associations that failed to connect at the TCP/IP layer. More than 50 is considered a minor alarm to investigate further. Failures could be caused by either end of the association. Check the CLB X DICOM component to determine if the failures are client side or node side. Client side faults indicate a problem with the remote entity.
Troubleshooting Alarms Attr. Code Description Recommended Action CMNA CMN Device Status; indicates the general status of the CMN service: • 0 = No errors • 10 = Errors If there is an Error, check the Overview and Alarm tabs for the device to find the cause of the error and to troubleshoot the problem. If the problem persists, contact HP technical support.
HPMA User Guide Attr. Code Description Recommended Action CsQT Count of CMS Synchronization messages that are queued to be sent to other CMS services. More than 50,000 is considered a minor alarm to investigate further. More than 1,000,000 is considered a critical condition. Ensure that other CMS services are online and running normally. Check the load on the system—if there have been a significant number of transactions this may be normal and will resolve itself over time.
Troubleshooting Alarms Attr. Code Description DEAE Count of inbound DICOM C-Echo failures. 50 is considered a minor issue. DEAF Count of inbound DICOM C-Find failures. 50 is considered a minor issue. DEAI Count of inbound DICOM C-Store failures. 50 is considered a minor issue. DEAM Count of inbound DICOM C-Move failures. 50 is considered a minor issue. DEAO Count of outbound DICOM C-Store failures. 50 is considered a minor issue. DEEO Count of outbound DICOM C-Echo failures.
HPMA User Guide Attr. Code Description Recommended Action DSNn HD Status; the status of each of the drives in a RAID unit: • 0 = No Errors • 1 = Rebuilding • 2 = Missing • 3 = Unknown • 4 = Failed • 5 = Spare • 6 = Replaced The letter n in the Attribute Code is an indicator of which RAID, as some servers are attached to multiple RAID units. All the drives are assigned to their respective array utilizing the Cid to distinguish each individual drive.
Troubleshooting Alarms Attr. Code Description Recommended Action FERR Sum of all errors reported by a network interface port. At 50, monitoring the situation is advised. At 100, a minor issue investigation is needed. At 500, the issue is considered major. Check that the adapter hardware and driver are correctly installed and configured to work with your network routers and switches. When the underlying problem is resolved, use the Configuration tab to clear the alarm. See page 170.
HPMA User Guide Attr. Code Description Recommended Action FRGF Files Retrieved from the Grid (Failed); a count of files requested through an FSG but have failed to be retrieved from the grid to the cache. Values of fifty or more are a minor concern. Ensure all CMS and LDR nodes are operating normally. If the value continues to increase, contact HP technical support. When the underlying problem is resolved, use the Configuration tab to clear the alarm. See page 163.
Troubleshooting Alarms Attr. Code Description Recommended Action FSTA FSG Total Available cache; a measure of remaining space on the server for caching content. Cache space is managed by the service. Space is freed as objects in the cache are no longer needed. Values less than 30 GB trigger alarms. Ensure all CMS and LDR nodes are operating normally. Check the following attributes in the FSG X Storage component: “Files Stored to Grid - Pending”, “File Store Rate”, and “File Retrieved Rate”.
HPMA User Guide Attr. Code Description Recommended Action Check the state of the LDR and the related Storage component. Ensure all are online. Check that the HTTP component is configured to autostart when the service is restarted (page 167). HSTE HTTP State; protocol component state: • 0 = Offline • 1 = Redirect • 2 = Online (Read-only) • 3 = Online If you are using the FSG service, it is critical that the HTTP protocol be online and running without errors.
Troubleshooting Alarms Attr. Code Description Recommended Action MSTU Status of the DICOM protocol component: • 0 = No Errors • 1 = Not Started • 2 = Invalid/Missing DICOM Dictionary • 3 = Starting... • 4 = Stopping... • 5 = Invalid/Missing Index Tag List Restart the service. If the error persists, it may indicate an installation problem. Contact HP technical support. NADC Number of ADCs the device is connected to. There should always be at least one ADC.
HPMA User Guide Attr. Code Description Recommended Action NCMS Number of CMSs the device is connected to. The system needs multiple CMSs to maintain fault tolerance and quality of service. If there is no connected CMS under LDR X Network, there are no CMSs available and end user functionality may be impacted. If there is no connected CMS under CMS X Network, there is at least one CMS running (itself) and system operation is not impacted. Restore connectivity to a CMS as soon as possible.
Troubleshooting Alarms Attr. Code Description Recommended Action NNMS Number of NMSs the device is connected to. Connections to the NMS do not affect client functionality, but do affect your ability to properly monitor the system. If there is no connection to an NMS, check the network connections and whether both servers and services are available. If this is not a hardware related issue and the problem persists, contact HP technical support.
HPMA User Guide Attr. Code Description Recommended Action PATn RAID controller status; indicates the status of the RAID monitoring and is not an indicator of the status of the RAID itself: • 0 = Online • 1 = Offline The letter n in the Attribute Code is an indicator of which RAID, as some servers are attached to multiple RAID units. The monitoring module is used to report statistics on the RAID. Under certain circumstances the monitoring module can become shut down or disconnected.
Troubleshooting Alarms Attr. Code Description Recommended Action PMEM Memory Usage (%); the percentage of RAM memory that is being used. Can have values “Over Y% RAM” where Y represents the percentage of memory being used by the server. Figures under 70% are normal. Over 95% is considered a major issue. If the memory usage is fairly high for a single device/service, this should be monitored and investigated.
HPMA User Guide Attr. Code Description Recommended Action PTEn Temperature State; an indication of the temperature status, summarizing the RAID temperature situation: • 0 = OK • 1 = Temp Low • 2 = Temp High • 3 = Critical • 4 = Unavailable The letter n in the Attribute Code is an indicator of which RAID, as some servers are attached to multiple RAID units.
Troubleshooting Alarms Attr. Code Description Recommended Action SLSA System Load Average; an indication of how busy the system is. The higher the value the busier the system. Typically above 10 should be investigated as it indicates a fairly high load on the system. Over 25 is considered a critical issue.
HPMA User Guide Attr. Code SPOP Description FSG Pending Operations; indicates the number of replication messages to be processed by a Secondary FSG. If this rises, it indicates that you are storing data faster than the Secondary FSG can process transactions. This normally declines during periods of reduced grid activity. There is a warning at 500, and a minor alarm if more than 1000. Recommended Action Stop storing files into the Primary FSG of the group.
Troubleshooting Alarms Attr. Code Description Recommended Action SSTE Storage State; an indication of the current status of the component: • 0 = Offline • 1 = Standby • 2 = Verify • 3 = Online (Read-Only) • 4 = Online If the Storage State goes into Verify, this means it is running through the data and verifying its data integrity; a normal operation. If the state is Online (Read-Only) new data cannot be stored into this LDR, but data can be requested and viewed. Standby state is a minor alarm.
HPMA User Guide Attr. Code Description Recommended Action SWMU System Swap Memory Used; measured in bytes. Values less than 100 MB are considered normal; over 500 MB is a major issue. If a service is persistently using large amounts of the virtual memory swap storage, upgrade the amount of RAM in the server. TNER Network Neighbor Drift; an indication in µs of how far the clock is drifting should it become disconnected from a GPS system. Absolute values more than 1,000,000 (1 s) are a minor issue.
Troubleshooting Alarms Attr. Code Description Recommended Action VMFI Volume Free entities; a measure of how many more objects the volume can store. Values below 100,000 start to raise a concern. When the value dips below 25,000 the situation is a major issue that should be addressed. Values below 10,000 are considered critical. This is an indication that additional storage is needed on the server. Contact HP technical support for assistance in installing and configuring new object storage.

HPMA User Guide Overview of Server Manager Each server used in an HP Medical Archive deployment runs the Server Manager application. The Server Manager program is used to supervise starting and stopping services on the server, ensuring services gracefully join and leave the grid. It also monitors services on the server, and attempts to restart any that report faults.
Introduction to Server Manager Capabilities Server Manager provides the following capabilities: • Stop and start all services on a server for: • Restarting grid services that have gone offline • Stopping the services in preparation for an upgrade • Bringing up the services after a reconfiguration • Detect OS shutdown and gracefully close services. • Restart a server; bring down everything, including the OS, and reboot the machine from the BIOS up.
HPMA User Guide Server Manager is designed to run whenever the server is running. Automatic Startup and Shutdown During system startup, Server Manager is automatically started by the operating system. Server Manager executes a sequential series of scripts to verify that support services are running, and start them as needed. The startup and shutdown sequences are reversed, ensuring that dependencies are in place as needed, and are not removed prematurely.

HPMA User Guide Display Components The Server Manager presents a Graphical User Interface (GUI) on the local console of the server. The display uses five panels to present information and controls. Header Service List Command Buttons Prompt Line Server Identification Figure 30: Server Manager Interface Sample Header The top of the screen presents a header line, identifying the Server Manager application and its overall status.
Server Manager Operation services are in an error state, the Status reports “Error”, and the header background turns red. Service List The body of the display is a list of the services being monitored by the Server Manager. Service Name The name of each service is shown. For grid services, the names are the fixed service names. Some services may appear that are not identified through the NMS. These are services that can run independently and provide support capabilities to the grid services.
HPMA User Guide Control Buttons Located in the bottom left corner are four control buttons used to stop and start services and reboot or halt the server. Use of these command buttons ensures the services enter and leave the grid gracefully. The currently selected button is shown with a yellow box around the button text. Figure 31: Sample Selected Button Use of these buttons is described in detail in “Command Operations” on page 204.
Server Manager Operation the installation disks. The server name used in that file is reported by Server Manager as the Host Name. IP Addresses The server’s operating system networking service is used to report the IP addresses assigned to the network interface(s). Most servers have only one address; however, if multiple adapters/addresses are available, all are reported. Prompt Line At the very bottom of the display is a prompt line, providing guidance on what actions you can take.
HPMA User Guide waiting for the display to “catch up” may result in activating the wrong command. Initiating an Action To initiate an action: 1. Press the key to cycle the highlight to the desired control button. Each press cycles to the next button in a standard rotation. 2. Press to indicate that you want to initiate the selected action. A confirmation dialog opens allowing you to confirm or cancel the action. 3. Use the key to select OK (confirming the action) or Cancel.
Server Manager Operation Starting Services This button is used to start services that have been stopped for upgrade or other configuration changes. Upon server startup, or when commanded via the Start All button, the Server Manager executes a series of scripts to initiate dependent applications in a sequence that ensures prerequisite services are running before starting the grid services themselves.
HPMA User Guide The Server Manager performs the same sequence as the Stop All command (page 205), then continues to bring down the operating system. The Server Manager and GUI are closed by the operating system as part of its shutdown. Settings in the operating system are used to trigger a reboot, which in turn restarts the Server Manager application. Server Manager then restarts the GUI and all services.
