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

When real-time charting is in progress, will it be impacted by either configuration
or performance data collections that are happening simultaneously?
No. When real time collection is in progress for an XP or a P9000 disk array through a host agent,
you can still initiate configuration and performance data collections on the same XP or P9000 disk
array through the same host agent, provided you select a different command device. You can also
select a different host agent for the configuration and performance data collections.
Why are XP10000 and XP20000 type disk arrays not listed under Select Com-
ponents on the RealTimeCharting screen?
The XP10000 and XP20000 type disk arrays are not displayed under Select Components, as the
real-time charting is supported only for XP24000 or XP12000 type disk arrays.
Why are ports and DKC not available for selection under Select Components
on the RealTimeCharting screen for an XP or a P9000 disk array?
The ports and DKC are not available for selection, as real-time data collection and charting is only
supported for the LDEVs and RAID groups.
Do RAID groups and LDEVs also include external RAID groups and virtual
volumes?
No. RAID groups and LDEVs for an XP or a P9000 disk array in the real-time charting context do not
include external RAID groups, ThP, continuous access, and snapshot virtual volumes.
How many RAID groups and LDEVs can I select for real-time charting? Can these
resources be selected across XP and P9000 disk arrays?
At a time, you can select only five LDEVs or RAID groups in an XP or a P9000 disk array to view their
real-time performance graphs. You cannot do the following:
• Select more than five LDEVs or RAID groups in an XP or a P9000 disk array
• Select a combination of LDEVs and RAID groups in an XP or a P9000 disk array
• Select a combination of LDEVs and RAID groups, or RAID groups across multiple XP and P9000
disk arrays
Why are the concatenated RAID groups not displayed for the XP and P9000
disk arrays under Selected Components on the RealTimeCharting screen?
Concatenated RAID groups are not displayed. Instead, only the first RAID group number from a
concatenated RAID group is displayed for your selection under RAID groups in the Selected Components
list.
I want to view real-time performance graphs for 10 LDEVs that belong to one of
the P9000 disk arrays? How can I view their real-time performance data?
Initiate real-time charting for the first set of five LDEVs. Then, initiate another instance of real-time
charting for the next set of five LDEVs, after stopping the first instance of the real-time charting.
