The dlnkmgr command's offline operation places online paths offline. Specify the paths to be placed offline by specifying an HBA port, CHA port, or single path. Instead of specifying a path, you can also specify a SCSI device name.
There must always be at least one online path accessing each LU.
Note that, for a path that is placed offline by the offline operation and whose status changes to Offline(C), the path status will not be inherited when the host is restarted. If the path is in a normal condition when the host is restarted, the path will become active and its status will be Online.
Placing too many paths offline might prevent paths from being able to switch if an error occurs. Before placing a path offline, use the view operation to check how many online paths remain. For details about the view operation, see view (displays information).
