For a VxVM cache area, you can set the following attributes:
memsz. The amount of system RAM that the SmartIO solution requires to keep VxVM caching-related metadata. When the VxVM cache area is created, SmartIO calculates the best possible value. You do not need to change this value, unless the system is low on system RAM.
association type. The association type is either --auto or --noauto. The association type determines whether caching is automatically enabled for volumes on the system.
To set the memory size
# sfcache set {dg/vol|cachearea_name} memsz=size
Where
dg/vol specifies the disk group and volume that is used for the cache area.
cachearea_name specifies the name of the cache area
size specifies the maximum size for the memory for in-core metadata.
For example:
# sfcache set myspecialcache memsz=128m
