4.1.10 Maintenance Tasks on Devices Connected by Paths in the

Boot Disk Environment

Note the following points when performing maintenance on devices connected to the

boot disk in a boot disk environment running Solaris:

Ensure that at least one path connected to the boot disk is online when you

perform a maintenance task.

Before starting maintenance, for any path that you expect to be disconnected

during the maintenance operation, execute the

dlnkmgr

command with the

offline

option to set the path to the Offline(C) status. If you do not change the

status and a path disconnection is detected during the maintenance, access to the

boot disk will be temporarily delayed. As a result, the system performance might

decrease. After you finish maintenance, immediately execute the

dlnkmgr

command with the

online

option to set the paths (that you set to Offline(C)) to

Online.
