NOTE:
The remaining capacity, which is calculated by subtracting Cache LUN XP Size and Partial
Cache Residence Size from Cache Size, must be 4 GB or more in CLPR0. If you changed
Cache Size, Cache LUN XP Size, or Partial Cache Residence Size, verify that the capacity
calculated by subtracting Cache LUN XP Size and Partial Cache Residence from Cache Size
remains 4 GB or more in CLPR0.
NOTE:
For more information about XP Cache LUN and Partial Cache Residence, see the HP StorageWorks
Cache LUN XP user guide for the XP12000/XP10000/SVS200.
• Apply: Applies settings.
NOTE:
You can make changes for more than one CU group before implementing the settings.
• Cancel: Cancels settings that were entered or selected, and restores settings to their initial values.
Creating CLPRs
If you have not yet created a CLPR, the entire cache appears in CLPR0 in the Partition Definition pane.
To partition the cache, create a CLPR. The created CLPR can be allocated to each SLPR. CLPRs can be
created in a selected SLPR.
IMPORTANT:
Disk/cache partitioning for the SVS200 is limited to one SLPR and four CLPRs.
NOTE:
Only the Administrators can create CLPRs.
NOTE:
If you create a CLPR, the default cache size is 4 GB. To create a CLPR, the desired cache size is allocated
from CLPR0 (entire cache).
NOTE:
To create a CLPR, the remaining cache size, which is calculated by subtracting Cache LUN XP Size and
Partial Cache Residence Size from the Cache Size of CLPR0, must be 4 GB or more.
1. Confirm the current CU group in the drop-down list for CU groups at the top of the pane.
NOTE:
To change the CU group, select the desired CU group from the drop-down list for CU
groups in the upper right of the XP Remote Web Console main pane. For more information
about CU groups, see the HP StorageWorks XP Remote Web Console user guide for
XP12000/XP10000/SVS200.
