HP StorageWorks P9000 Performance Advisor Software v5.2 User and Troubleshooting Guide (T1789-96315, June 2011)

can be configured as either 2D+2D or 7D+1P. The 4-way parity group concatenation is configured
as 7D+1P. The system supports RMLIB version 1.12.04 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” on page 255.

Double-click a Journal group volume ID in the Jnl Group column to open the Journal Group Detail
View screen, as shown in Journal Group detail view and Journal Status. 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 displayed
under the Journal Volume Status tab.
