To remove a device from a cache area

1. Make sure that the cache will fit on the remaining devices after you remove the device. If necessary, resize the cache to a size smaller than the size of the remaining devices.

   If you shrink a VxFS cache area, all of the cached data (including statistics) might be evicted.

   # sfcache resize newsize cachearea_name

   For example, suppose the current cache area sfcachearea_1 has a maximum size of 5G. You want to remove an SSD ssd0_0 that is 2G. First, resize the cache area to 2.5G:

   # sfcache resize 2.5g sfcachearea_1

2. To remove a device from a cache area, specify the device by the disk access name to remove the cache area.

   # sfcache rmdev [daname ...]

   For example, to remove the SSD ssd0_0:

   # sfcache rmdev ssd0_0

3. Optionally, you can use the maxsize option to resize the cache area to the maximum size that fits on the remaining devices in the cache area.

   # sfcache resize maxsize cachearea_name

   For example:

   # sfcache resize maxsize sfcachearea_1
