Viewing data for prominent set of metrics
When you select an application, host, or WWN for an XP array, the performance data of LDEVs,
ports, CLPRs, and RAID groups is displayed on the Troubleshooting screen for the following prominent
set of metrics.
Table 6 Prominent metrics for LDEVs
DescriptionDefault metricsResources

Response time.
Avg Read/Write Resp TimeLDEVs
Total IO/s happening on the LDEVs.IOPS
Total MB/s of data written to the
LDEVs.

In addition, the replication status for LDEVs is also displayed under Replication Attribute. This data
helps you to know if a particular LDEV is being used as a replication volume (Cont. Access volume
or Business Copy volume). For are the example replication statuses:
• SMPL(CA)/SMPL(BC): Indicates that the LDEV is not configured as a Cont. Access or BC volume.
• PVOL(CA)/SMPL(BC): Indicates that the LDEV is configured only as a PVOL for Cont. Access.
Further, the performance data for ports, CLPRs, and RAID groups is also retrieved for the following
prominent metrics.
