2. Verify that supported JRE is installed by entering java -version at the command line prompt (from
the management station home directory).
Cause
Performance data collection may stop on all the XP or P9000 disk arrays connected to a host, if the
command device used belongs to an array group where a disk failure occurred.
Resolution
To start the performance data collection again:
1. From the list of host records under the Host Information tab in P9000 Performance Advisor, select
the host record on which performance data collection stopped.
2. Click Request Info and wait until the status is updated to show as Received. This verifies that the
host and management station are communicating with each other.
3. Delete the existing performance data collection schedule and create a new schedule for the se-
lected host under the Performance Collection tab in P9000 Performance Advisor.
Cause
The configuration data collection fails or the PerformanceAdvisorXP.log displays the following
error: PerformanceAdvisor: Failed to start config data collector transfer
for <Array Serial #>: com.hp.xpsl.hostagent.RmlibException: RMLIBbased
DKC configuration is empty for <Array Serial #>
Resolution
To resolve the issue:
1. Create a GUID on the Windows host. See the topic, “Assigning GUIDs for command devices on
a Windows host agent” in the HP StorageWorks P9000 Performance Advisor Software Installation
Guide. For document download location, see Related information.
2. Restart the Windows host agent services.
3. From the list of host records under the Host Information tab, select the host record on which per-
formance data collection stopped.
4. Click Request Info and wait until the status is updated to show as Received. This verifies that the
host and management station are communicating with each other.
5. Initiate configuration and performance data collection.
Cause
The performance data collection schedules might not be created.
Resolution
Verify that schedules are created for the performance data collection under the Performance Collection
tab. Data does not appear until two data collection intervals have elapsed. For more information, see
the HP StorageWorks P9000 Per formance Advisor Software User Guide. For document download
