Removing a cache

You can remove a cache completely, including the cache object, its cache volume and all space-optimized snapshots that use the cache.

 To remove a cache completely, including the cache object, its cache volume and all space-optimized snapshots that use the cache

1. Use the following command to find out the names of the top-level snapshot volumes that are configured on the cache object:

   # vxprint -g diskgroup -vne \

     "v_plex.pl_subdisk.sd_dm_name ~ /cache_object/"

   where cache_object is the name of the cache object.

2. Remove all the top-level snapshots and their dependent snapshots.

   This can be done with the following single command:

   # vxedit -g diskgroup -r rm snapvol ...

   where snapvol is the name of a top-level snapshot volume.

3. Stop the cache object, with the following command:

   # vxcache -g diskgroup stop cache_object

4. Remove the cache object and its cache volume, with the following command:

   # vxedit -g diskgroup -r rm cache_object
