Setting the java heap size values
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 arrays that are visible to a
particular host agent. You can decrease the total number of LDVEs 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” (page 68).
NOTE: By default, the heap size value for fresh installation is set to a minimum of 512 MB and
a maximum of 1024 MB. For the upgrade process, the heap size value is set to a minimum of
1024 MB and maximum of 1536 MB.
Setting the heap size for management station
To set the heap size value on a management station:
1. Select Start+Programs+HP StorageWorks+HP XP 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.
3. If you type y at the prompt, you are further prompted to provide the minimum and maximum
java heap size values.
The minimum heap size value must be more than or equal to 512 MB, and the maximum heap
size value must be less than or equal to 2048 MB. If heap size values are already set, the
current minimum and maximum heap size values are also displayed for your reference.
If you type n at the prompt, the command prompt window closes.
