Follow these guidelines when using the snapdrive storage disconnect command:

  • 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 storage disconnect command fails if you use it to disconnect file systems that are attached to a single mountpoint.

  • If you use the -lun option to specify the name of a LUN that is a member of either a host disk group, or a file system, the snapdrive storage disconnect command fails.

  • If you use -lun option to specify the name of the LUN that is not discovered by multipathing software on the host, the snapdrive storage disconnect command fails.

Note snapdrive storage disconnect command fails while using RDM LUN, if the mapping igroup has more than two World Wide Port Names (WWPN), in releases prior to SnapDrive 5.2 for UNIX.
