1. Choose an option or enter the information into the fields:
• Storage Pool — the storage pool targeted in tests (All or one specific storage pool).
• Compression Ratio — the compressibility ratio for data written during a Background job. For
instance, if 2:1 is selected, the data created will be compressible at 2:1 and decompressed
when read back. This exercises the disks more thoroughly than without compression. A com-
pressibility ratio of at least 2:1 is recommended.
• Number of Concurrent Streams — the number of streams (up to six) running read or write
operations at the same time. The larger the number, the more the storage system is stressed.
NOTE:
A Background job can only involve one stream unless multiple storage pools are present.
• Notification — the notifications displayed on the Notifications tab. Choose to generate noti-
fications per time period (in hours and minutes) or per number of job iterations. The notifications
provide links to detailed information about the jobs performed. (This configuration option is
only available for some VLS firmware versions.)
2. Click Save as Default. The Storage Exerciser uses this information throughout the operation.
If you encounter problems with the Storage Exerciser, select Restart Storage Exerciser Service from
the task bar. All jobs currently in progress will stop and report a status of Complete.
Storage Exerciser CLI Commands
If you have root access to the VLS, you can configure the jobs at the command line. You can also
retrieve reports from /var/log/hp/exerciser/exericser_report.log; see “
Log File
Fields ” on page 195 for an explanation of the report fields.
The command options are start, stop, and status.
Examples:
/S2100/hp/exerciser/secl start -t readonly -p all -s 3
/S2100/hp/exerciser/secl start -t background -p 1 -s 4 -c 3 -D 10 -T 01:30
/S2100/hp/exerciser/secl stop -t readonly
/S2100/hp/exerciser/secl status -t readonly
Where:
test type: readonly or background -t
storage pools: all or use the number of the individual storage pool -p
concurrent streams: 1 to 6 (the default is 1) -s
compressibility: 1 to 4; 1=1:1, 2=2:1, 3=3:1, 4=4:1. Only applicable to a Background test. -c
data limit in GB. Only applicable to a Background test. -D
time limit: HH:MM. Only applicable to a Background test. -T
