For example, to see how much space is used and how much remains available in
all cache objects in the diskgroup mydg, enter the following:
# vxcache -g mydg stat
Growing and shrinking a cache
You can use the vxcache command to increase the size of the cache volume that
is associated with a cache object:
# vxcache [-g diskgroup] growcacheto cache_object
size
For example, to increase the size of the cache volume associated with the cache
object, mycache, to 2GB, you would use the following command:
# vxcache -g mydg growcacheto mycache 2g
To grow a cache by a specified amount, use the following form of the command
shown here:
# vxcache [-g diskgroup] growcacheby cache_object
size
For example, the following command increases the size of mycache by 1GB:
# vxcache -g mydg growcacheby mycache 1g
You can similarly use the shrinkcacheby and shrinkcacheto operations to reduce
the size of a cache.
See the vxcache(1M) manual page.
