Guidelines for disconnecting Snapshot copies
Contributors Download PDF of this page
The following are the guidelines to disconnect a Snapshot copy for LUNs, storage entities, or NFS directories.
When you disconnect a file system, SnapDrive for UNIX always removes the mountpoint.
Linux hosts allow you to attach multiple file systems to a single mountpoint. However, SnapDrive for UNIX requires a unique mountpoint for each file system. The
snapdrive snap disconnectcommand fails if you use it to disconnect file systems that are attached to a single mountpoint.
To undo the effects of the Snapshot connect operation, use the Snapshot disconnect command.
If you set the
enable-split-cloneconfiguration variable value to
syncduring the Snapshot connect operation and
offduring the Snapshot disconnect operation, SnapDrive for UNIX does not delete the original volume or LUN that is present in the Snapshot copy.
