HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

CAUTION:
Ensure that the date and time on the management station and the hosts are synchronized with the
local time zone to receive accurate configuration data. This condition is also applicable for the client
systems that use the IE browser to access P9000 Performance Advisor on a management station, and
the systems that have the CLUI software installed.
The following are important notes applicable for both the one-time and scheduled configuration data
collection:
• Select only one command device for an XP or a P9000 disk array to perform the configuration
data collection for that array.
• When a configuration data collection is in progress for an XP or a P9000 disk array, do not initiate
another configuration data collection for the same array.
• The configuration changes made to an XP or a P9000 disk array after a one-time collection is not
automatically updated in P9000 Performance Advisor. You must perform the one-time configuration
data collection again to receive the latest configuration data for that XP or P9000 disk array.
However, if you have scheduled the configuration data collection for an XP or a P9000 disk array,
P9000 Performance Advisor automatically retrieves the latest configuration data as per the selected
schedule frequency.
• When an inband or an outband configuration collection is in progress for an XP or a P9000 disk
array, do not re-initiate the current configuration data collection for the same array.
• If an XP or a P9000 disk array is connected to a host agent that is running on HP-UX 11i v3 oper-
ating system, the DSF is displayed in a new format. A legacy DSF is displayed in parenthesis next
to the new format.
• Components 101-16483 represent the external RAID group information collected using the outband
mode.
• The outband mode of configuration data collection is only supported for the P9500 Disk Array
and the XP24000, XP20000, XP12000, and XP10000 Disk Arrays.
• With every outband mode of configuration data collection for an XP or a P9000 disk array, P9000
Performance Advisor gets the latest internal raw disk capacity of that XP disk array or the latest
usable capacity of that P9000 disk array. These values are updated under Array Capacity (TB)
on the License screen. So, it is necessary that the SVP for the XP or the P9000 disk array be online,
accessible, not locked by any other user, or under maintenance.
• If an outband mode of configuration data collection is in progress for an XP or a P9000 disk array,
P9000 Performance Advisor stops collecting configuration data in the following cases:
• If the usable capacity of a P9000 disk array or the internal raw disk capacity of an XP disk
array cannot be updated
In such a case, P9000 Performance Advisor displays the following appropriate error message
under the Configuration Collection tab:
Array capacity data could not be fetched through SVP for the XP disk
array <serial_num> or P9000 disk array <serial_num>. Ensure that the
XP disk array or the P9000 disk array is online, the SVP is accessible
and not under maintenance, or locked by another resource. The outband
configuration data collection will not be allowed for this XP disk
array until the problem is resolved.
Simultaneously, an event is also logged on the Event Log screen. If you have scheduled a
configuration data collection, a failure notification message is also sent to the recipient email
address, specified in the Data Collection Email Settings section on the Email Settings screen.
