Setting the java heap size values
To ensure optimal performance and results, the maximum number of LDEVs is restricted to 6000. To
increase the maximum number of LDEVs to 16000, increase the memory allocated to the JVM when
you start the host agent and management station services. These values must be set using the Resize
Heap tool, if you want to view the performance of XP and P9000 disk arrays with large number of
LDEVs (64K binary (65,536)).
NOTE:
To ensure optimal performance and results, the maximum number of LDEVs for data collection is
6000. This is the total number of LDEVs across all XP and P9000 disk arrays that are visible to a
particular host agent. You can decrease the total number of LDEVs visible to a host agent, by restricting
the LDEVs that are visible to the host. You can increase the maximum number of LDEVs visible to a
host agent, by increasing the number of LDEVs that are visible to the host. For information on increasing
the number of LDEVs that are visible to the Host Agent, see “For the management station” on page 80.
Setting the heap size for management station
To set the heap size value on a management station:
1. Select Start > Programs > HP Storage Works > P9000 Performance Advisor > Resize Heap.
You can also go to the <Install_drive>:\HPSS\bin folder and double click on the
ResizeHeapMS.bat file.
2. In the command prompt window that appears, read the 'Important' note given at the beginning
and then respond to the prompt as appropriate.
