In addition, the following are displayed:
•
The MP blade ID with its corresponding average utilization percentage in brackets. For
example, MPB-1MA [9.34].
MPB-1MA is the MP blade ID that belongs to the Cluster 1 and the blade location MA. Its
average utilization percentage is 9.34%.
•
The replication status for the LDEVs under Replication Attribute. This data helps you to
understand if a particular LDEV is being used as a replication volume (continuous access or
business copy volume). The following are the example replication statuses:
◦
SMPL(CA)/SMPL(BC): Indicates that the LDEV is not configured as a continuous access
or business copy volume.
◦
PVOL(CA)/SMPL(BC): Indicates that the LDEV is configured only as a continuous access
primary volume.
◦
SMPL(CA)/SVOL(BC): Indicates that the LDEV is configured only as a business copy
secondary volume.
Further, the performance data for the ports, CLPRs, and the RAID groups is also retrieved for the
following prominent metrics.
Table 28 Default metrics for RAID groups, ports, and CLPRs
Description
Default metrics
Resources
The total utilization of each DKA pair
associated with a RAID group.
DKA Util %
RAID groups
IMPORTANT:
Since, the ACP/DKA
MPs are moved to the MP blades in the
P9000 disk arrays, the DKA Util % metric
is not applicable for the P9000 disk
arrays. It is applicable only for the XP
disk arrays.
The total utilization of each RAID group.
RG Util %
The total I/Os happening through the
ports.
IOPS
Ports
The total MB/s of data transferred
through the ports.
MBPS
The average of individual MP utilization
on each port.
MP Util %
IMPORTANT:
Since, the CHIP/CHA
MPs are moved to the MP blades in the
P9000 disk arrays, the MP Util % metric
is not applicable for the P9000 disk
arrays. It is applicable only for the XP
disk arrays.
The percentage of data pending to be
written to an LDEV.
Write Pending %
CLPRs
The percentage of data read from an
LDEV.
Read Hit
the total Percentage of CLPR usage data.
Cache Usage
Troubleshooting using host group or WWN 335
