Operation 25
Error indication on the last path
When the state of the paths is displayed with dlnkmgr view –path
command, the last path for a device remains online. It does not go offline
even if an error occurs. The path containing an error is now indicated as
Online(E).
• The Online(E) path returns online if input and output can be
successfully executed.
•The dlnkmgr online command or automatic failback returns the
Online(E) path online only.
Using the dlnkmgr online command
If –pathid is not specified in the dlnkmgr online operation, all the paths in
hold state are subject to online processing. If there is a path that cannot be
recovered, the following message is output:
A path which failed to go online was detected during
online operation of the KAPL01039-W DLM command. Do
you want to continue the PathID = %d online
operation? [y/n]? Enter "y" to continue the
operation, or "n" to abort it.
When –s is specified, the operation is continued on the assumption that “y”
is specified.
You can execute the dlnkmgr view –path command to show the status of
the LUN paths.
# dlnkmgr view –path
