HP XP P9000 Performance Advisor Software v6.0 User Guide

is configured as 7D+1P. The system supports RMLIB version 1.16.04 and later. If there is an LDEV
that is associated with two RAID groups, data about both the RAID groups are displayed.
If LDEVs are associated with multiple RAID groups (such as in 4D+4D configurations where the
LDEV is mirrored on two different RAID groups), these multiple RAID groups are treated as separate
sets of items. For example, if you have an LDEV with RAID group 1-1 1-2, you must select 1-1 1-2
in the drop-down menu. An LDEV mapped to 1-1 1-2 is treated separately from a RAID group
mapped only to 1-1 or only to 1-2.
You can also view detailed information for a RAID group, such as the data transfer and backend
transfer information, average and maximum read response, average and maximum write response
for each LDEV. Click the corresponding RG ID in the CLPR window. The line above the RAID group
table indicates the hierarchical information of the selected RAID group. For more information on
view CLPR information, see “CLPR detail view” (page 227).
Continuous Access Journal Detail View
Double-click a Journal group volume ID in the Jnl Group column to open the Continuous Access
Journal Detail View screen, as shown in Journal Group detail view. A list of LDEVs configured in
the continuous access journal volume displays; a maximum of 16 LDEVs display. The status on
backend transfers and average read response of each LDEV associated with the journal group is
also shown. Additionally, for a P9000 disk array, the MP blade processing the I/O requests for
the journal LDEVs is also shown.
