HP StorageWorks XP Performance Advisor Software v4.6 User and Troubleshooting Guide (T1789-96094, June 2010)

Following are important notes applicable for both the one-time and scheduled configuration data
collections:
• To perform configuration data collection for an XP array, select only one command device for that
XP array.
• Do not initiate configuration data collection at the same time for multiple XP arrays.
• Configuration changes made to an XP array after a one-time collection are not automatically up-
dated in XP Performance Advisor. You must perform the one-time configuration data collection
again to receive the latest configuration data for that XP array. However, if you have scheduled
the configuration data collection, XP Performance Advisor automatically retrieves the latest config-
uration data from the XP array as per the selected schedule frequency.
• When Inband or OutBand configuration collection is in progress, you cannot reinitiate the config-
uration data collection.
• If an Inband or OutBand collection fails, wait for the progress bar to stop before reinitiating a
new configuration data collection. It takes approximately 60 minutes for the progress bar to reset
after an Inband collection failure.
• If an array is connected to a host agent that is running on HP-UX 11i v3 operating system, the
Device Special File (DSF) is displayed in a new format. A legacy DSF is displayed in parenthesis
next to the new format.
• Resources 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 XP10000, XP12000,
XP20000, and XP24000 disk arrays.
• With every Outband mode of configuration data collection, XP Performance Advisor gets the latest
internal raw disk capacity from your XP Disk Array (XP10000, XP12000, XP20000, XP24000)
and updates its value under Array Capacity (TB) on the License screen. So, it is necessary that the
SVP belonging to the particular XP Disk Array be online, accessible, and not locked by any other
user or under maintenance.
• XP Performance Advisor stops collecting configuration data for those XP disk arrays (XP10000,
XP12000, XP20000, XP24000), for which internal raw disk capacity cannot be updated, license
has expired, or license capacity has exceeded the grace period.
If internal raw disk capacity cannot be updated for an XP Disk Array through Outband, XP Per-
formance Advisor displays the message, Array Raw capacity data could not be
fetched through SVP for XP Disk Array 10055. Ensure that the XP 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 re-
solved. under the Configuration Collection tab. Simultaneously, an event is also logged for the
same 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. For more information, see “Configuring email
and SNMP settings” on page 76.
If license has expired or license capacity has exceeded the grace period for an XP Disk Array,
XP Performance Advisor displays the message, Configuration collection is stopped
due to license violation for array under the Configuration Collection tab. Simultan-
eously, an event is also logged for the same on the Event Log screen.
• The internal raw disk capacity got through the Inband mode of configuration data collection is
not accurate when compared to the value shown by RWC, and might lead to license violations.
So, if you want accurate internal raw disk capacity of your XP Disk Array (XP10000, XP12000,
XP20000, or XP24000), HP recommends that you collect configuration data using the Outband
mode.
