2 Preparing for the upgrade Before starting the XCS upgrade, you should perform several tasks to minimize the time required to complete the upgrade. The tasks you perform depend on your system configuration and the HP Command View EVA implementation. These tasks focus on upgrading system components to ensure they meet the supported configuration for XCS 09534000. Table 5 on page 46 provides a checklist so you can track your progress as you perform these pre-upgrade tasks.
NOTE: For details on EVA software compatibility, see Table 1.0, the EVA software version compatibility table and Table 2.0, the HP Command View EVA interoperability support table, in the HP StorageWorks Enterprise Virtual Array Compatibility Reference. See “Required documentation” on page 10 for the link to this document. Table 2 Management software version worksheet Software Current version Required version (minimum) Locating version information1 Upgrade procedure HP Command View EVA (required) 9.

If there are any hardware caution or warning conditions, click the Hardware folder to expand it. The Hardware Folder Properties window opens (Figure 3 on page 16). The Operational State field indicates if there is a hardware problem. Figure 3 Hardware Folder Properties window . b.
2. Replace any hardware components that have failed. NOTE: To replace any components, see the user guide for your array model for information about replacement. See Table 1 on page 10 for links to these guides. TIP: If there is a yellow attention icon, you may still be able to do the upgrade, for example, when leveling is occurring. If any unusual icons are visible, check with your HP-authorized service representative before doing the upgrade.
Collecting SAN configuration data using SAN Visibility IMPORTANT: SAN Visibility is only available for server-based management. HP provides the SAN Visibility tool to automate the process of collecting SAN configuration data. SAN Visibility collects configuration information from the Fibre Channel switches on your SAN. Any information provided by devices when they log into the fabric is included.
3. Select SAN Settings and enter the following information: a. Enter a name in SAN Name. You can use the default SAN Name, but HP recommends that you change it to a name that is meaningful to you. This name is used when generating reports, so it should be one that is easily recognized as being associated with the SAN on which data collection will be done.
4. 20 Click Switch Settings and enter the following information: a. Enter the IP Address of the primary switch for the SAN for which you want a report. Information will be collected for all devices connected to this switch. b. Clear Discover cascaded switches. This option automatically detects all switches connected to the switch identified by the IP address. Including all the cascaded switches increases the data collected for the report to include all the devices connected to all the switches.
5. Select Customer Details and enter the following information: a. Enter your name in Name. This information is required. b. Enter your e-mail address in E-Mail to receive the completed report. This information is required. It is not necessary to have an e-mail address connected to the EVA controller. You should enter the e-mail address where you typically receive e-mail. You can enter multiple email addresses in E-Mail by separating entries with a semicolon (;). c.
dropdown list. If you have external e-mail access from your environment, this is the preferred method. • Manually—Requires you to send your data manually to HP to obtain a SAN Visibility report. If you do not have external e-mail access, use this method. Creating a report automatically 1. Click Data Collection. 2. Select the fabric for which you want to create a report from the Choose switch group for data collection. Check Collect data for all switch groups to create reports for all the fabrics. 3.
Creating a report manually To obtain the SMTP server for the e-mail address you entered on the Customer Details window, select the Automatically e-mail the collected raw data on completion checkbox. If SAN Visibility does not find the SMTP server or if you want to create a report manually, follow the procedure below. 1. Click Data Collection. 2. Select the fabric for which you want to create a report from Choose switch group for data collection.
Reading the report 1. Save the attached file (.hppr file) to a preferred location. Do not change the file extension. 2. Double-click the saved file to extract the processed report. The processed report is extracted and stored at: \ExtractedProcessReports\\. 3. Click on the .hppr file to open the report in your browser. 4. In the left navigation pane, click High Level Fabric Summary. The High Level Fabric Summary window opens (Figure 5).
Evaluating your configuration The following factors can affect the success of an online upgrade. Consider these factors when determining if an online upgrade is appropriate for your environment. • Queuing host I/O—After the upgrade, the array performs a resynchronization. During the resynchronization, host I/O is queued to the host, which can create a backlog of requests for processing when the array is able to respond.
NOTE: In the formula, (allocated capacity) is the total of all virtual disks, snapshots, snapclones, mirrorclones, and containers. (allocated capacity) + (15 * DR log allocated capacity) + (14 TB * number of DR groups) If the result is less than the allocated capacity values cited for the number of virtual disks you have, an online upgrade is supported. If it is more than the values cited, you must do an offline upgrade.
NOTE: When determining an appropriate time to do an online upgrade, ensure that no configuration-related replication tasks (creating or deleting DR groups, snapshots, snapclones, mirrorclones or presenting to hosts) are being performed. Analyzing storage system I/O using HP Command View EVAPerf The HP Command View EVAPerf tool included with HP Command View EVA can be used to gather and analyze statistics on storage system utilization.
HP Command View EVAPerf command options The following options are used with the HP Command View EVAPerf commands: • -csv: Use comma separated output. This format is useful for importing large amounts of data into a spreadsheet for analysis. • -cont n: Runs the command continuously at an interval specified by n. The default interval is one second. • -dur n: Specifies the duration of a continuous mode session.
Identifying virtual disk activity If you cannot locate a period that meets the necessary I/O load requirements, it may be possible to identify specific applications that are imposing heavy I/O loads, and suspend them long enough to perform the upgrade. This can be done by using HP Command View EVAPerf to view virtual disk activity. For example, after running HP Command View EVAPerf, you determine that all the virtual disks on the storage system are nearly idle with the exception of one virtual disk.
Figure 7 Sample virtual disk statistics display . Table 3 HP Command View EVAPerf virtual disk statistics Counter Description Read Hit Req/s The number of read requests per second completed from the array cache memory. Data may reside in the cache memory due to a previous cache miss or because of a prefetch operation generated by a sequential read data stream. Read Hit MB/s The rate at which data is read from the array cache memory because of read hit requests.
Counter Description Mirror Data Rate The rate at which data travels across the mirror port to complete read and write requests to a virtual disk. This data is not related to the physical disk mirroring for Vraid1 redundancy. Write data is always copied through the mirror port when cache mirroring is enabled for redundancy. In active/active controllers, this counter includes read data from the owning controller that must be returned to the requesting host through the proxy controller.
IBM AIX Checking or changing timeouts AIX requires the disk settings shown in Table 4 for the native multipath drives. Table 4 IBM AIX timeout settings Setting Value Description PR_key_value NA Sets the key value for persistent reservations. Persistent reservations are not supported. Algorithm fail_over Sets the load balancing algorithm to fail_over. All I/O uses a single path. The remaining paths are in standby mode. The value round_robin is not supported.
• • • • • login_retry_count = 30 failover = 0 load_balancing = 1 excludemodel = 0x0 auto_restore = 0xA0 Emulex Driver parameters (single path) • • • • HPELXLPFC=y nodev_timeout=60 qdepth=30 discovery_threads=1 Emulex Driver parameters (with Multipulse) • nodev_timeout=10 • qdepth=16 • discovery_threads=32 To check or set Linux parameters, use the set_parm executable found in the /opt/hp/ directory. When executed, the options to change timeout values are displayed.
• If you are in a VMware environment where you are running as a Windows guest, see “VMware” on page 35. Checking timeout values The key timeout setting in the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\Disk\TimeoutValue should be set to 3c (60 seconds), which is the Microsoft Windows default. If the registry entry does not exist, you must create it. See your Windows documentation for instructions.
set sd:sd_io_time = 60 set ssd:ssd_io_time = 60 For QLogic, edit the /kernel/drv/qla2300.conf file and change the hbax-link-down-timeout value to 60 as follows: hba0-link-down-timeout=60; For Emulex, edit the /kernel/drv/lpfc.conf file and change the linkdown-tmo value to 60 as follows: linkdown-tmo=60; VMware VMware ESX (Hypervisor) does not time I/O for a guest operating system. Thus the SCSI timeouts on commands issued by each VMware guest (Linux, Windows, Solaris) are those provided for these systems.
Managing application I/O timeouts for an online upgrade Applications are typically insulated from the online controller firmware upgrade by the operating system and HBA driver software. Consequently, if the application is running on a properly configured operating system, the online controller upgrades will be performed successfully. It may be necessary to determine if any applications have timeout requirements that are more stringent than those of the operating system.
Before beginning the upgrade, it is recommended that you perform a full verified backup of all storage system data. Although not required, it is always good practice to back up your data before performing major operations such as software upgrades. The backup should be scheduled as close to the upgrade process as possible. For more information about establishing and implementing good backup procedures for the EVA, contact your HP sales representative.
Upgrading on a management server This procedure is for the typical HP Command View EVA installation on a management server. To use the custom installation procedure, which provides control over which components are installed, see the HP StorageWorks Command View EVA Installation Guide for instructions. To install the complete software suite: 1. Close all applications running on the management server. 2. Insert the installation CD into the drive. 3. Browse to the installation CD. 4.
Verifying the installation on the management server To verify that the software was installed successfully: 1. Ensure that the software icons for HP Command View EVA , HP Command View EVAPerf and/or HP Storage System Scripting Utility appear on the desktop. 2. Run HP Command View EVA. 3. Verify the display of storage system resources in the interface. In the navigation pane, click Hardware and verify the following: • New, uninitialized arrays appear as uninitialized storage systems.
3. Open a browser and browse to the WOCP (Web-based Operator Control Panel): https://HP EVA storage system IP address:2373 NOTE: • If you are running a version of management module software earlier than 0001.1000 (which corresponds to XCS 09004000 or earlier), use port 2372. • If you have not previously set the IP address for the management module, the default is 192.168.0.1.
1. On the WOCP login window, log in as an HP EVA administrator (username admin and the password). NOTE: The password, if set before the upgrade, is maintained during the upgrade. 2. The WOCP GUI appears. Click View detailed system information and verify the Operation state, XCS version, and the management module software version. To verify that HP Command View EVA was upgraded successfully: 1.
24x7 to ensure maximum system availability by providing intelligent event diagnosis, and automatic, secure submission of hardware event notifications to HP, which will initiate a fast and accurate resolution, based on your product’s service level. Notifications may be sent to your authorized HP Channel Partner for on-site service, if configured and available in your country.
Monitoring storage system stability Estimated time to complete: 25–30 minutes When to perform: 48 hours before beginning the upgrade The storage system configuration should be stable for 48 hours before beginning the upgrade. Check the status of the array to ensure it is stable and then continue monitoring status until the upgrade begins. 1. Open HP Command View EVA and click the icon of the storage system you want to upgrade. 2.
3. Verify that no changes to the storage system configuration are in progress. For example, you should not be in the process of creating a virtual disk. Configuration changes should not be made within 48 hours before beginning the upgrade. Proactive event notification can be used to alert you if a critical event occurs during the 48 hours before the upgrade. NOTE: • The leveling process does not impact the upgrade. If leveling is in progress, the upgrade can be performed.
1. 2. Click the Data Replication folder in the navigation pane. Check the Connection State in the Data Replication Folder Properties window. • All EVA storage systems must be running normally with fully functional controller pairs.
TIP: When capturing the HP Command View EVA configuration, it is a best practice to specify the SAVE ALL option. This helps to capture critical data such as the WWN, useful for rebuilding the array configuration. NOTE: You cannot use the utility to restore a configuration that contains disk drives of different capacities. You must manually restore that type of configuration.
Task Task complete Checking and upgrading your SAN infrastructure, page 17 Time required: After collecting and evaluating data on your configuration over several weeks, you can determine when is an appropriate time to do the upgrade.
