2 Pre-upgrade tasks You should perform several tasks before starting the upgrade to minimize the time required to complete the XCS upgrade procedure. The required tasks differ depending on your system configuration and HP Command View EVA implementation. They focus on upgrading components to ensure they meet the supported configuration for XCS 6.220. Table 5 provides a checklist so you can track your progress as you perform these pre-upgrade tasks.
NOTE: For complete details on EVA software compatibility, see the “EVA software solution compatibility” table and 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 HP Command View EVA (required) HP Replication Solutions Manager (if installed) Required version (minimum) 1.
Checking the HP Command View EVA version NOTE: If upgrading from HP Command View EVA version 6 to version 7 or later, licenses must be migrated. See the HP Command View EVA installation guide for more information. To check the HP Command View EVA version, perform the following steps: 1. Open HP Command View EVA on the management server. The HSV Storage Network Properties window opens. Figure 1 HSV Storage Network Properties window . 2. Click Help in the Session pane.
When to perform: 1–2 weeks prior to the upgrade, and then daily until the upgrade is completed. Provide enough time to order and replace any failed components. Before upgrading your Enterprise Virtual Array, you should check the operation of the storage system hardware and replace any failed components. This ensures the storage system will be operating properly when the upgrade is performed.
2. Verify that there are no hardware components in the Unmappable Hardware folder. a. Expand the navigation tree under the Hardware folder in the Navigation pane. b. Click the Unmappable Hardware folder. Hardware components can be placed in the Unmappable Hardware folder for several reasons. For example, hardware components can be placed in the Unmappable Hardware folder, when the I/O modules on a disk enclosure are not working, the controllers restart, or there is a hardware failure.
NOTE: Using SAN Visibility is optional. SAN Visibility requires Java Runtime Environment (JRE) 1.5.0 Update 1 or later. You can download the most current JRE version from Sun's website: http://www.sun.com/ Installing SAN Visibility SAN Visibility is typically installed on the management server running HP Command View EVA. 1. Download SAN Visibility from the following website: http://h18006.www1.hp.com/products/storageworks/san/index.html Click SAN Visibility under Networking Solutions. 2.
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. b. Click Rename. c. Click Yes to confirm the name change. d. Select the fabric in the tree view. e. Enter a name in Switch Group Name.
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 connected switches. This option automatically detects all switches connected to the switch identified by the IP address. Including all the connected switches increases the data collected for the report.
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.
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. Clear Capture Performance data for this switch. If you want to gather switch performance data, leave this option selected. Selecting this option will increase the amount of time required to collect the switch data. 4.
3. Clear Capture Performance data. If you want to gather switch performance data, leave this option selected. Selecting this option will increase the amount of time required to collect the switch data. 4. Select Mask IP Address check box if you do not want to send the IP address information (in the raw report) outside your network. 5. Select a format for the report by selecting HTML Report or Microsoft Excel Report check box. 6. Click Start Data Collection.
5. For each switch, compare the indicated firmware (FW) version to the switch firmware supported by XCS 6.220. This information is listed on the Single Point of Connectivity Knowledge (SPOCK) website (http:/ /www.hp.com/storage/spock). You must sign up for an HP Passport to enable access. Once access is enabled, select Compatibility Tool in the left menu and then select Fibre Channel Switch. You can refine your search by switch brand.
• Criticality of business applications—Ensure that you do not select a time when critical business applications could be affected. • I/O load—Selecting a period of low I/O activity helps to ensure that the upgrade completes as quickly as possible, and avoids disruptions to host and applications due to timeouts. While there are advantages to performing an online upgrade, there are circumstances when it is not advisable.
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 6 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.
• • • • 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. NOTE: • The timeout values must be increased for Emulex single path (without multipath support) and QLogic single path being used in the environment.
NetWare No changes are needed for NetWare operating system timeouts. The default values from HBA are: • Login retry count: 8 • Port down retry count: 16 • Link down timeout: 8 OpenVMS The limit for LUN timeout is 120 seconds. NOTE: OpenVMS handles the controller reboot seen at the conclusion of the firmware update process. Disks on the controller display a Mount Verify status during the controller reboot but regain Mounted status and resume I/O operations upon the completion of the controller reboot.
Online controller software upgrades are supported in Trucluster 4–node environments where the EVA is the cluster boot device. 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. NOTE: For Microsoft Windows guests, set the Windows SCSI timeout registry to 60 secs as follows: 1.
IMPORTANT: It is crucial that you check application timeouts to verify that they are equal to or longer than the timeout thresholds for the upgrade. Although an application may survive the online controller software upgrade successfully, there may be an impact on performance. To minimize the performance impact on users, the online upgrade should be performed during a period of low user activity.
Upgrading using the typical installation This procedure is for the typical HP Command View EVA installation. 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.

3. 4. HP Command View EVA responds with the page. The web server sends it to the browser. These errors indicate that a problem is occurring with this normal interaction. Table 7 lists some possible causes of these errors and their corrective actions. Resolution Table 7 Possible causes and corrective actions for HTTP 404 and HTTP 503 errors Possible Cause Corrective Action 404 Error: HP Command View EVA may be initializing when a browser makes a request.
Unknown storage system—cause 2 HP Command View EVA can only manage controllers that are running supported XCS versions. Corrective Action for Unknown Storage System—Cause 2 Ensure that you are running the HP Command View EVA version that is compatible with XCS 6.220. See the "HP Command View EVA interoperability support" table in the HP StorageWorks Enterprise Virtual Array compatibility reference to determine which version of HP Command View EVA you should be running.
Possible Cause A storage system may not be visible to HP Command View EVA because the controllers are waiting for World Wide ID (WWID) to be entered. This condition will occur if the storage system has been uninitialized and the cabinet is power cycled. Corrective Action Enter the WWID. This may also occur if backend problems are preventing access to the quorum drives. Once communication is restored, the WWID along with the checksum can be re-entered.
Figure 23 Status icon for a good storage system . If the status icon for the storage system is not a green cluster, it indicates a problem that must be corrected before proceeding. Expand the navigation tree to locate the problem. Figure 24 illustrates a storage system with a controller problem and a disk enclosure problem. Figure 24 Status icon for a bad storage system . Solving problems disabling DR group failsafe mode There are a number of issues that may occur with HP Continuous Access EVA.
NOTE: The XCS firmware image file name has an extension of .sss. The file name contains the controller model (200 for EVA4x00, and EVA6x00 or 210 for EVA8x00) and the XCS version. For example, 210_6220.SSS is the name of the XCS 6.220 file for the HSV210 controller. Invalid firmware image file (Status code 21006) If the XCS firmware image file is the wrong image, an Operation failed message is displayed. See Figure 25. Click OK to return to the Initialized Storage System Properties window.
