HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

DescriptionDefault metricsResources
The average utilization of the MP
blades that are associated with the
LDEVs.
NOTE:
The average utilization displayed
is for the last one hour.
The MP blade average utilization
data is collected during the DKC
performance data collection. The
collection frequency set for the
DKC data collection might be
different from that set for the
LDEV data collection. So, the DKC
data collected in the last one hour
will provide the most recent data
for the MP blades.
MP Blade Util (%)
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 20 Default metrics for RAID groups, ports, and CLPRs
DescriptionDefault metricsResources
The total utilization of each DKA
pair associated with a RAID group.
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.
