The PI_RGSX record stores performance data indicating the performance of a parity group, external volume group, and a virtual volume group.

Note:

All the CU numbers of the LDEVs that belong to the target parity group must be set to be monitored for the record to be created.

Collection Interval

3600

Key Field

RAID_GROUP_NUMBER

Lifetime

From when the parity group is set up to when it is removed
