The Snapshot restore operation of the file system on raw LUN fails after performing a Snapshot connect operation on a non-originating host.
When the cloned LUN is connected to the same filespec in a Snapshot copy and then you try to execute the snapdrive snap restore command, the following error message appears.
"0001-034 Command error: mount failed: mount: <device name> is not a valid block device"
The command fails because the iSCSI daemon remaps the device entry for the restored LUN when you delete the cloned LUN.
You can do any of the following:
snapdrive snap restorecommand again.
Delete the connected LUN (if it is mounted on the same filespec as in Snapshot copy) before trying to restore a Snapshot copy of an original LUN.
