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 about the

view operation, see 6.7 view (Displays

Information).

-hba host-port-number.bus-number

Use this parameter to place offline, at one time, all the paths that pass through a

specific HBA port. The command will place offline all the paths connected to the
