The drive is online, but it is not currently active. Blinking irregularly Off The drive is active and operating normally. Off Amber; blinking regularly (1 Hz) Offline; the drive is not being accessed.
Table 6 Disk drive LED combinations (continued) Online/Activity (green) Fault/UID (amber/blue) Blinking regularly (1 Hz) Off Description CAUTION: Do not remove the drive. Removing a drive may terminate the current operation and cause data loss. The drive is rebuilding. Off Off Either there is no power, the drive is offline, or the drive is not configured. 1. This Fault/UID state can indicate that the disk is a leftover. The fault may involve metadata on the disk, rather than the disk itself.
LED Description Definition 10 Cache Status Green — Cache is dirty (contains unwritten data) and operation is normal. The unwritten information can be log or debug data that remains in the cache, so a Green cache status LED does not, by itself, indicate that any user data is at risk or that any action is necessary. Off — In a working controller, cache is clean (contains no unwritten data). Blinking green — A CompactFlash flush or cache self-refresh is in progress.

7 Configuring a system for the first time Configuring your web browser for SMU Before using SMU to perform remaining steps, ensure that your web browser is properly configured according to the following guidelines: • Your browser must be Mozilla Firefox 1.5 or Microsoft Internet Explorer 6, or later. For better performance, use Firefox or Internet Explorer 7 or later. NOTE: Check the QuickSpecs for currently supported browsers. QuickSpecs can be found from your HP MSA products page at http://www.hp.
• The System Status panel shows how many events of each severity have occurred in the system. To view event details, click a severity icon. • Do not use the browser's Back, Forward, Reload, or Refresh buttons. SMU is essentially a single page that is automatically updated to show current data. You do not need to refresh it, and if you click Back, you may exit the application. • An asterisk (*) identifies a required setting. • Many tables can be sorted by a specific column.
To obtain the date and time from an NTP server 1. In the Configuration View panel, right-click the system and select Configuration > System Settings > Date, Time. The date and time options appear. 2. Set the options: • NTP. Select Enabled. • NTP Time Zone Offset. Optional. If the system timestamps should use the NTP server's time zone instead of the local time zone, enter the time zone offset. • NTP Server Address. Optional.
Using the Configuration Wizard The Configuration Wizard helps you initially configure the system or change system configuration settings. The wizard has several steps, which are highlighted at the bottom of the panel as you complete them. The last step prompts you to confirm changes before applying them. If you cancel the wizard, no changes are made.
Using the Provisioning Wizard The Provisioning Wizard helps you create a vdisk with volumes, and to map the volumes to hosts. The wizard has several steps, which are highlighted at the bottom of the panel as you complete them. The last step prompts you to confirm changes before applying them. If you cancel the wizard, no changes are made.

8 Troubleshooting Fault isolation methodology The 2000sa G2 Modular Smart Array storage system provides many ways to isolate faults within the system. This section presents the basic methodology used to locate faults and the associated FRUs (Field Replaceable Units).
Correcting enclosure IDs When installing a system with drive enclosures attached, the enclosure IDs might not agree with the physical cabling order. This is because the controller might have been previously attached to some of the same enclosures during factory testing and it attempts to preserve the previous enclosure IDs if possible. To correct this condition, make sure that both controllers are up, and perform a rescan using SMU or the CLI.
Are both drive module LEDs off (Online/Activity and Fault/UID)? Answer Possible Reasons Actions Yes • There is no power. • Check that the drive is fully inserted and latched in place, and that the enclosure is powered on. • The drive is offline. • The drive is not configured. Is the drive module Fault/UID LED blinking amber? Answer Possible Reasons Actions No, but the The drive is rebuilding. Online/Activity LED is blinking. No action required. Yes, and the The drive is offline.
Is a connected port’s Expansion Port Status LED off? Answer Possible Reasons Actions No System functioning properly. No action required. Yes The link is down. • Check cable connections and reseat if necessary. • Inspect cable for damage. • Swap cables to determine if fault is caused by a defective cable. Replace cable if necessary. • In SMU, review event logs for indicators of a specific fault in a host data path component. • Contact an authorized service provider for assistance.
Is the drive enclosure Fault/Service Required LED amber? Answer Possible Reasons Actions No System functioning properly. No action required. Yes (blinking) One of the following errors occurred: • Check the event log for specific information regarding the fault. • Hardware-controlled power-up error • Isolate the fault. • Cache flush error • Replace if necessary. • Contact an authorized service provider for assistance. • Cache self-refresh error Yes A fault occurred.
Controller failure in a single-controller configuration Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write to CompactFlash process only the components needed to write the cache to the CompactFlash are powered by the super-capacitor. This process typically takes 60 seconds per 1 Gbyte of cache. After the cache is copied to CompactFlash, the remaining power left in the super-capacitor is used to refresh the cache memory.
Isolating a host-side connection fault During normal operation, when a controller module host port is connected to a data host, the port’s host link status LED and host link activity LED are green. If there is I/O activity, the host activity LED blinks green. If data hosts are having trouble accessing the storage system, and you cannot locate a specific fault or cannot access the event logs, use the following procedure. This procedure requires scheduled downtime.
Isolating a controller module expansion port connection fault During normal operation, when a controller module’s expansion port is connected to a drive enclosure, the expansion port status LED is green. If the connected port’s expansion port LED is off, the link is down. Use the following procedure to isolate the fault. This procedure requires scheduled downtime. NOTE: Do not perform more than one step at a time. Changing more than one variable at a time can complicate the troubleshooting process. 1.
Sensor locations The storage system monitors conditions at different points within each enclosure to alert you to problems. Power, cooling fan, temperature, and voltage sensors are located at key points in the enclosure. In each controller module and expansion module, the enclosure management processor (EMP) monitors the status of these sensors to perform SCSI enclosure services (SES) functions. The following sections describe each element and its sensors.
Table 9 Controller module temperature sensors (continued) Description Normal operating Warning range operating range Critical operating range Shutdown values Onboard temperature 2 0–70°C None None None Onboard temperature 3 (Capacitor temperature) 0–70°C None None None CM temperature 5–50°C <=5°C, >= 50°C <=0°C, >= 55°C None When a power supply sensor goes out of range, the Fault/ID LED illuminates amber and an event is logged to the event log.
A Environmental requirements and specifications Safety requirements Install the system in accordance with the local safety codes and regulations at the facility site. Follow all cautions and instructions marked on the equipment. Site requirements and guidelines The following sections provide requirements and guidelines that you must address when preparing your site for the installation.
Weight and placement guidelines Refer to Physical requirements on page 59 for detailed size and weight specifications. • The weight of an enclosure depends on the number and type of modules installed. • Ideally, use two people to lift an enclosure. However, one person can safely lift an enclosure if its weight is reduced by removing the power and cooling modules and drive modules. • Do not place enclosures in a vertical position. Always install and operate the enclosures in a horizontal orientation.
NOTE: Connections to this device must be made with shielded cables with metallic RFI/EMI connector hoods in order to maintain compliance with FCC Rules and Regulations. Physical requirements The floor space at the installation site must be strong enough to support the combined weight of the rack, controller enclosures, expansion enclosures, and any additional equipment.
Electrical requirements Site wiring and power requirements Each enclosure has two power and cooling modules for redundancy. If full redundancy is required, use a separate power source for each module. The AC power supply unit in each power and cooling module is auto-ranging and is automatically configured to an input voltage range from 88–264 VAC with an input frequency of 47–63 Hz. The power and cooling modules meet standard voltage requirements for both U.S. and international operation.
B Electrostatic discharge Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers.
