Description
Detail for CLPR in Sys- tem
Allows you to set or change the settings of the specified cache logical partition. See “Cache Logical Partition Operations” on page 31 for more information on cache logical partition operations.
You cannot directly change the capacity value of CLPR 0. Any changes in the capacity of the other CLPRs will be reflected in the capacity of CLPR 0.
The maximum available cache capacity (mounted cache less the cache in use by other cache logical partitions) displays for the upper limit of Cache Size, Cache Residency Size, Num. of Cache Residency Areas. For more information on Cache Residency, see HP StorageWorks XP24000/XP20000 Cache Residency Manager User's Guide.
•CLPR Name allows you to set or change the name of the cache logical partition, provided that it is within the selected CU. You can use up to 16 alphanumeric characters.
•Cache Size setting, as illustrated in Figure 7 on page 21, allows you to set or change the cache capacity of each cache logical partition. You may select 4 GB or more up to a maximum size of 508 GB, which is 4 GB smaller than the cache size of the whole storage system. From a default value of 4 GB, you may increase the size in 2 GB increments. Cache Residency Size setting, also illustrated in Figure 7 on page 21, allows you to set or change the capacity of the Cache Residency cache. You may select nothing (0 GB) to a maximum size of 504 GB, which is the Cache Residency size of the entire storage system. The default value is 0 GB, to which you may add capacity in 0.5 GB increments.
•Cache Residency Size allows you to set or change the capacity of the Cache Residency cache. The value of Cache Residency size must be selected or input from 0 to 248 GB in 0.5 GB increments. The default value is 0 GB.
Note: If you have previously defined cache residency size for this cache logical partition using Cache Residency Manager, the Cache Residency size selected for this cache logical partition must be greater than that which was previously defined. Use Cache Residency Manager to verify the size before you set the value for this field.
•Num. of Cache Residency Areas allows you to set or change the number of Cache Residency areas, from 0 to 16,384. The default value is 0.
NOTE:
If you have previously defined Cache Residency areas for this cache logical partition using Cache Residency Manager, the number of Cache Residency areas selected for this cache logical partition must be more than that which was previously defined. Use Cache Residency Manager to verify the number of areas before you set the value for this field.
