HP StorageWorks P9000 Performance Advisor Software v5.4 Troubleshooting and FAQs Guide (T1789-96336, April 2012)

Can I set the threshold values for LDEVs on the Threshold Settings screen?
No. Threshold values cannot be set for LDEVs. Instead, you can set threshold values only for the ports,
cache, RAID groups, and DKC resources.
The frontend, cache, and backend categories on the Dashboard screen are
showing the X icon for the P9000 disk array. Does it indicate that the P9000
disk array is not optimally utilized?
Not necessarily. It just indicates that the resources in your P9000 disk array have crossed the threshold
limits that you set for them on the Threshold Settings screen.
There is no activity in my P9000 disk array. However, the categories show the
X icon. What does it indicate?
This can occur in cases where the threshold is set to very low non zero values (for example, 1 for
IOPS or 1MBPS). Ensure that you set appropriate values on the Threshold Settings screen to view the
accurate health of your P9000 disk array.
What does -1 indicate for the Frontend, Backend, Cache, or MP Blade (applic-
able only for P9000 disk arrays) category on the Threshold Settings screen?
If -1 is displayed for the Frontend, Backend, Cache, or MP Blade category, it means that the
performance threshold values are not yet configured for the XP or the P9000 disk arrays. In such
cases, the usage summary is also disabled on the Dashboard screen.
NOTE:
The following FAQs are on enhancements or new features introduced in Array Dashboard from v4.5
onwards.
Why are LDEV records not displayed in the LDEV Information table on the
Dashboard screen?
The LDEV records are not displayed in the LDEV Information table on the Dashboard screen, if there
is no I/O activity on the LDEVs for the set threshold duration.
NOTE:
The LDEV Information table is available on the Dashboard screen from P9000 Performance Advisor
v4.5 onwards.
Why is Show LDEVs disabled on the Dashboard screen?
The Show LDEVs disabled on the Dashboard screen in the following cases:
• If more than one frontend or backend record is selected in the Statistics section on the Dashboard
screen
• If you are viewing the statistics for the cache usage
