Viewing Parity Group data
Consider the scenario of five RAID groups (preferably belonging to the same drive type). You want
to know which is the least busiest RAID group, so that you can provision storage space from the RAID
group to create new LDEVs in that RAID group. P9000 Performance Advisor helps you to identify the
least utilized RAID group by providing the backend I/O metric and utilization metric graphs for the
five RAID groups that you select in P9000 Remote Web Console. The I/O metric data provides an
indication of the I/O load that is currently handled by the individual RAID group.
Before you start provisioning, ensure that the RAID group has sufficient storage space.
To view the parity group data:
1. Complete steps 1 and 2 mentioned under “Launching P9000 Performance Advisor” on page 377.
2. Select Parity Groups in the list displayed for the P9000 disk array serial number.
NOTE:
The navigation path Parity Groups > Internal is not supported in this version.
3. In the right work area, select the parity group record for which you want to view the usage and
performance data in Performance Advisor.
