Guidelines for disconnecting Snapshot copies

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 disconnect command 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-clone configuration variable value to on or sync during the Snapshot connect operation and off during the Snapshot disconnect operation, SnapDrive for UNIX does not delete the original volume or LUN that is present in the Snapshot copy.
