VLS9200 user guide (BW402-10009, August 2012)

• Number of Concurrent Jobs — the number of read or write operations (called streams)
running at the same time. The larger the number, the more the storage system is stressed;
you can run up to six at once.
NOTE: A Background job can only involve one stream unless multiple storage pools
are present.
• Notification Generation Options — the notifications displayed on the Notifications tab.
Choose to generate notifications 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.)
6. 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 (page 157) for an explanation of the report fields.
The command options are start, stop, and status.
Examples:
/S2100/hp/exerciser/sbin start -t readonly -p all -s 3
/S2100/hp/exerciser/sbin start -t background -p 1 -s 4 -c 3 -D 10 -T
01:30
/S2100/hp/exerciser/sbin stop -t readonly
/S2100/hp/exerciser/sbin 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
Starting and Reviewing Read-only Jobs
To run a Background job, from the Configuration tab:
1. Make changes to the default configuration if necessary; see “Configuring the Storage
Exerciser” (page 153).
2. Select the Read-Only Job tab.
This tab displays information for all previous and current Read-only jobs. The Storage Pool
and Number of Concurrent Jobs fields contain the default information entered in the
Configuration tab.
