upgrade process. Selecting a period of low I/O activity will ensure the upgrade completes as quickly as possible, and will avoid disruptions to host and applications due to timeouts. When performing an online upgrade, select a time period that meets the following criteria: • I/Os per second (IOPS) should be less than 7000 • I/O throughput should be less than 70 MB/s NOTE: The above values apply when upgrading the EVA4x00/6x00/8x00 storage systems. These values do not apply to EVA3000/5000 storage systems.
• -dur n: Specifies the duration of a continuous mode session. For example, if you enter evaperf hps -cont 2 -dur 30, host port data is displayed at two second intervals for a total of 30 seconds. • -sz array: Limits data collection to the specified array(s). You must enter at least one array and can use either the storage system WWN or friendly name. • -fo filename: Directs output to a specified filename. Include the path information as necessary.

a snapshot, snapclone, or a DR group member. In the output, logical unit number (LUN) is used interchangeably with virtual disk. Virtual disks must be presented to a host to be seen by HP Command View EVAPerf. However, replication volumes on the replication system are visible without being presented. Because the storage system controllers are active/active, one controller is preferred (the owning controller) but requests can still be processed by the other controller (the proxy controller).
Figure 7 Sample virtual disk statistics display Table 6 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.
Displaying EVA performance data using Windows Performance Monitor An alternative for capturing and displaying EVA performance metrics is Windows Performance Monitor. This tools provides a graphical presentation that you may find more useful for analyzing EVA performance data. See the HP StorageWorks Command View EVA user guide for more information about using Windows Performance Monitor.
Checking timeout values • The key timeout setting is in the registry at HKEY_LOCAL_MACHINE/SYSTEM/ CurrentControlSet/Disk/TimeoutValue should be set to 3c (60 seconds) HP-UX CAUTION: Because HP-UX supports boot across Fibre Channel SAN, any change to default SCSI timeouts on the HP-UX host may cause corruption and make the system unrecoverable.
• discovery_threads=1 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. This is not only important for online upgrades but for general data integrity. • Online controller firmware upgrades are supported with Linux boot devices.
IBM AIX Checking or changing timeouts AIX requires the disk settings shown in Table 7 for the native multipath drives. Table 7 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.
