HP StorageWorks P9000 Performance Advisor Software v5.4 User Guide (T1789-96328, April 2012)

• 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 P9500 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 P9500 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.
For more information, see “Configuring email and SNMP settings” on page 88.
• If the license has expired or licensed capacities have exceeded the grace period for an XP or
a P9000 disk array
In such a case, P9000 Performance Advisor displays the following error message under the
Configuration Collection tab:
Configuration collection is stopped due to license violation for array
<serial_number>
Simultaneously, an event is also logged on the Event Log screen.
• The internal raw disk capacity of an XP disk array obtained through the inband mode of configur-
ation data collection is not accurate when compared to the value displayed by the Remote Web
Console. It might lead to license violations. If you want to view the accurate internal raw disk ca-
pacity of an XP disk array, HP recommends that you collect the configuration data using the outband
mode.
For a P9500 disk array, both the inband and the outband mode of configuration data collection
provide the accurate usable capacity (same as displayed by Remote Web Console).
• There might be a difference in the total count of continuous access journal volumes received through
the inband, and the outband modes of configuration data collection for a P9000 disk array.
This is because, the configuration data collected through the inband mode includes data on only
the registered and active continuous access journal volumes. However, the configuration data
collected through the outband mode includes data on the initialized volumes in addition to the
registered and active volumes.
Tasks you can perform under the Configuration Collection tab
• “Collecting configuration data” on page 62
• “Scheduling configuration data collection” on page 65
