To view the summary of overall utilization of RAID groups for an XP or a P9000 disk array, click
RG Summary in the component selection tree for that XP or P9000 disk array. This feature totals
the LDEV I/Os, LDEV MB/s, cache fast write, disk fast write, cache bypass, and backend transfer
values for all the LDEVs on a given RAID group. In addition, it also displays the percentage of the
RAID Group utilization random read, random write, random write parity, sequential read, sequential
write, sequential write parity, and the overall RAID group percentage utilization (sum of the above
percentages) on a given RAID group.

IMPORTANT:
•

The RAID group utilization percentage is not displayed for external storage volumes.

•

The Auto LUN XP software must be installed, and monitoring must be enabled on the
XP1024/XP128 Disk Array for the RAID group utilization metric to be available on these
arrays.
