•
Physical Capacity Usage — includes the total physical capacity and the physical capacity
used by individual libraries and storage pools.
•
Logical Capacity Usage — includes the total logical capacity and the logical capacity
used by individual libraries.
•
Replication Traffic — shows the total amount of replication data transferring across the
LAN/WAN.
5. Select the report format you prefer. Some reports only use CVS format, while some include
HTML as an option.
6. Select the frequency of the automated report. The options are one-time (as of the moment you
add the report), hourly, daily, weekly, and monthly.
7. The Time, Day of Week, and Day of Month lists appear based on the frequency you selected.
For example, if you select Weekly, you can then set the Time and Day of Week you want the
reports to run.
8. Select Add. The system will run the report and email it to you at the next opportunity based
on your settings.
9. Repeat the steps above to receive multiple reports.
Stress Testing Hard Disks using the Storage Exerciser
Systems running some VLS firmware versions can stress test physical storage to ensure the integrity
of the hard disks using the Storage Exerciser tool. (Because it can affect overall performance,
however, HP recommends not running the Storage Exerciser unless it is advised by HP support
personnel.) The Storage Exerciser provides two types of test jobs:
•
Background — enables a user to initiate a low resource test job that continually writes and
reads a small amount of data at regular intervals.
•
Read-only — reads and decompresses all data currently residing on the VLS by opening each
non-empty, non-hidden cartridge. All data is decompressed but not copied to any other location
or made available to any other device.
NOTE: Storage Exerciser jobs will slow down other VLS operations. Do not start a job when the
performance of other VLS operations is critical.
Configuring the Storage Exerciser
In the Configuration tab, you can assign default settings for reports.
To customize the Storage Exerciser, from Command View VLS:
1.
Select the System tab.
2. From the navigation tree, select Chassis.
3. From the task bar, select Storage Exerciser. A caution screen indicates that running a job will
affect your system's overall performance.
4. Click Accept. The Storage Exerciser opens to the Configuration tab.
5. Choose an option or enter the information into the fields:
•
Storage Pool — the storage pool targeted in tests (All, or one specific storage pool).
•
Compressibility 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 compressibility ratio of at least 2:1 is recommended.
