HP StorageWorks P9000 Performance Advisor Software v5.2 Release Notes (T1789-96318, August 2011)

• The HP StorageWorks P9000 Performance Advisor Software User Guide is updated to state that
the database related tools or functionalities should be executed with the same privilege that is
used to install P9000 Performance Advisor, and that the user should be a member of the ORA_DBA
Windows group.
• P9000 Performance Advisor and HP Systems Insight Manager Agents can co-exist on the same
management station from v5.2 onwards.
• P9000 Performance Advisor can co-exist with IIS on all the supported Windows platforms from
v5.2 onwards. During the prerequisites check for P9000 Performance Advisor v5.2 installation,
if the installation wizard detects that the IIS Admin service is active, the service is automatically
stopped and the startup type set to Manual, so that the installation can proceed.
After the installation is complete, you can start the IIS Admin service again only if P9000 Perform-
ance Advisor is configured to use a http port other than the one IIS Admin service uses.
• The P9000 Performance Advisor Windows host agent is supported on a Windows 2008 R2 op-
erating platform, where JRE v5.0 Update 18 (minimum) to JRE v6.0 Update 18 (maximum), or JRE
v6.0 Update 24 is installed.
• In the LDEV I/O report - Frontend LDEV Mapping table, a hyphen (-) is displayed in the RAID
Format column if the RAID format of that particular RAID group is not applicable for the ThP pool
V-Vols.
• The outband mode of configuration data collection does not fail even if the configured V-Vol ca-
pacity is more than 1.98TB.
• After performing an inband mode of configuration data collection, if you re-issue the configuration
collection, the list of ports selected in the corresponding performance data collection schedules
are retained and not automatically removed. A similar issue pertaining to outband mode of con-
figuration data collection is also resolved.
• If a ThP pool consists of pool volumes from multiple ACPs or DKAs, P9000 Performance Advisor
uses a new metric called the Combined Backend Transfer metric to report the overall backend
transfers at the ACP or DKA levels. The backend transfers contributed by all the V-Vols in a ThP
pool are reported as the Combined Backend Transfer metric for each participating ACP or DKA.
The Combined Backed Transfer metric is applicable only for the XP24000 and P9000 (P9500)
disk arrays.
• P9000 Performance Advisor displays correct serial numbers across all the screens for the P9500
Disk Arrays that have serial numbers greater than 65535. Also, the license keys can be generated
at the HP Authorization Center (HPAC) website and installed in P9000 Performance Advisor for
such disk arrays.
• If you created two performance data collection schedules for an XP or a P9000 (P9500) disk array
and edit one of the schedules, the data in both the schedules is not swapped anymore.
• In Thin Provisioned environments, P9000 Performance Advisor uses a new metric called the
Combined Backend Transfer metric to report the overall backend transfers at the RAID group levels.
The backend transfers contributed by all the V-Vols in a ThP pool are combined and reported as
the Combined Backend Transfer metric for each participating RAID group.
Notes
• All XP/P9500 FICON, ESCON channel, CHIP Port IDs are listed as, ‘Not Mapped’ on the Array
View LDEV screen.
• FICON, ESCON CHA, port level metrics are not available in XP and P9500 disk arrays, therefore,
port metrics values are presented as ‘0’ in all P9000 Performance Advisor screens.
• All RAID group level and LDEV volume level performance metrics, are supported by P9000 Per-
formance Advisor, including mainframe volume emulation types.
• In a 100% ThP environment, the Dashboard Backend Statistics displays zero values as the backend
metrics for an XP or a P9000 (P9500) disk array. This is because, the I/O per second data and
