HP XP P9000 Performance Advisor v5.5 Software Troubleshooting and FAQs Guide (T1789-96344, February 2013)

1. Archive performance data for the XP and P9000 disk arrays using the database archival
functionality and later import the data back onto the same management station or another
management station where HP XP P9000 Performance Advisor is newly installed.
2. Backup the data using the Backup Utility and later restore that data onto the same management
station or another management station where HP XP P9000 Performance Advisor is newly
installed.
NOTE: Ensure that the HP XP P9000 Performance Advisor versions on both the source and target
management stations are the same.
For more information on archiving and importing data, or using the Backup utility, see the HP XP
P9000 Performance Advisor Software User Guide.
After removing Performance Advisor v3.4.1 on the management station, I did not delete the HPSS
folder and started with the v4.5 installation. After the installation completed, I am not able to log
into Performance Advisor. Why?
As you did not delete the HPSS folder when you removed v3.4.1 and later installed v4.5, the
HPSS folder will contain both SOLID and Oracle files. Remove v4.5, delete the HPSS folder
manually, and reinstall v4.5 on the management station.
