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.
