6.4 offline (Places Paths Offline)

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.
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 on the

view

operation, see 6.7 view (Displays

Information).
