Removing Volume Mappings from a Server
1 Make sure the volume is no longer in use.
2 In Enterprise Manager’s Storage view, expand Storage Centers if necessary and select the appropriate
Storage Center. (Do not select
Fluid Cache Clusters or its contents.)
3 In the Storage tab, expand Servers if necessary and locate the server whose Fluid Cache mappings you
want to remove.
4 Right-click the server and select Remove Mappings.
The Remove Mappings window is displayed.
5 In the Remove Mappings window, select the volume and click OK.
There may be some delay while the mapping is removed and dirty data in the cache is flushed to main
storage. When the mapping removal is complete, the volume’s icon in the Storage tab turns from blue
to gray color. You may need to manually refresh the display.
NOTE: The Fluid Cache mappings for the server are listed in the Volumes area at the bottom of the
page.
Removing Volume Mappings from a Subcluster
1 In Enterprise Manager’s Storage view, expand Storage Centers if necessary and select the appropriate
Storage Center. (Do not select Fluid Cache Clusters or its contents.)
2 In the Storage tab, expand Servers, and then the Fluid Cache clusters if necessary and select the
subcluster whose mappings you want to remove.
3 In the right pane, below the list of servers, select the volume and click Remove Mappings.
There may be some delay while the mapping is removed and dirty data in the cache is flushed to main
storage. When the mapping removal is complete, the volume’s icon in the Storage tab turns from blue
to gray color. You may need to manually refresh the display.
NOTE: The Fluid Cache mappings for the subcluster are listed in the Volumes area at the bottom of
the page.
NOTE: All Fluid Cache volume mappings must be removed before a server can be removed from a
Fluid Cache cluster.
Removing Volumes
To avoid the potential for performance issues and data loss, it is a recommended best practice to unmount,
remove, and delete all volume information after the volume is no longer in use.
Note that this is a general guideline pertaining to all Dell Compellent installations, and is not specific to Fluid
Cache.
For more information and the procedure for removing volume information, refer to the section about
removing volumes in Red Hat Enterprise Linux (RHEL) 6x Best Practices.
