View Performance Graphs For Ldevs - HPE XP7 User Manual

LDEVs and the related RAID Groups that have less frequently used data. The charts displayed show the
read/write and the I/Os for the selected LDEVs and their associated RAID Groups. Further, based on the
data projected, you can decide on the data that needs to be migrated to lesser used volumes. Use HPE
XP7 Tiered Storage Manager to move data from the source volumes to other target volumes that satisfy
the performance (Service Level Objectives) for that data. This is especially useful in cases where the
performance required for the volumes changes with the passage of time.
IMPORTANT:
Launch PA from HPE XP7 Tiered Storage Manager to view the usage data of the LDEVs and the
related RAID Groups only for the XP, P9500, and XP7 disk arrays.
You can launch PA from HPE XP7 Tiered Storage Manager v7.6.1-00 onwards. Once launched, the
charts for the LDEVs are displayed in the PA GUI for all the XP disk arrays that PA supports. For more
information, see the manuals set provided for the HPE XP7 Tiered Storage Manager Software the HPE
Manuals page. You can launch PA for the Migration Group volumes and the Storage Tier volumes, and
also in the Create Migration Task operation to facilitate selection of source and target volumes.
IMPORTANT:
• The locations of the PA management station and other parameters are defined in the HPE XP7
Tiered Storage Manager hppa.properties file. For more information, see the HPE XP7
Tiered Storage Manager Software Administrator Guide.
• If you have already logged in to PA using the specified management station address, the PA
login screen is not displayed. Instead, the PA screen is displayed, where you can select the
metric and the duration to view the graphs.
