Export LDEV data

You can export LDEV data to an Excel spreadsheet for the date and time range that you specify. The data
for all the LDEVs monitored by PA during the specified start and end date, and time are exported to a
spreadsheet in a CSV format.
1. Select the date range from the Start Date and End Date calendars.
2. Select the time range from the respective hour : minutes : seconds lists.
3. Click Export to Excel.
4. Click OK to continue.
A record for the export activity is logged in the Event Log screen. The record includes the name of the
XP or XP7 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.
The LDEV data is exported to the CSV file located at: Local_drive:\HPSS\pa\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).

View RAID Group information

Click an 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 1.16.04 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.

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. 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 an P9500/XP7 disk array, the MP
blade processing the I/O requests for the journal LDEVs is also shown.
