A record for the export activity is logged in the Event Log screen. The record includes the name
of the XP or P9000 disk array, and the date and time when the export activity was initiated.

After the data is exported, another record is logged in the Event Log screen. In addition to the
disk array, the date and time stamp, the record also includes a link to download the CSV file.

The following image displays the records logged for the XP disk array, 82502.

The LDEV data is exported to the CSV file located at: Local_drive:\HPSS\Tomcat\Webapps\
pa\export

. All CSV files are available in this specified location. The local drive on the management

station refers to C:, which includes the Windows operating system and the HPSS folder. A separate
CSV

file is created for every export operation. The existing CSV file is not replaced by the new file.

The file format is as follows: LDEV_<Array>_Timestamp. (Timestamp refers to the date and time
when the export operation is initiated).

IMPORTANT:

The port type, such as Fibre, Ficon, Escon, or FCoE (applicable only for P9000 disk arrays) is
displayed beside the CHIP port ID.

If the LDEV data is exported for a P9000 disk array, the LDEV data includes the MP blades assigned
to the LDEVs during the selected duration. Each MP blade ID includes the cluster # and the blade
location. For example, if MPB-1MA is the MP blade ID, 1 indicates the cluster # and MA indicates
the blade location for MPB-1MA.

Viewing RAID group information

Click a RG ID item in the LDEV table to view the RAID Group details and disk mechs details. The Disk
Mech displays the 2-way and 4-way parity group concatenation. The 2-way parity group concatenation
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
