If the SCSI device name mapped with the path to the relevant HDLM
device is represented with a hyphen (-) in the execution result, this
means that the path was in disconnected status.
Perform this operation if necessary. If it is not necessary to check this, go
to step 2.

.
Connect the cable.
If the cable is broken, replace it.
3
.
Restart the host on which the HDLM is installed.
The SCSI device is recreated, the path to the HDLM device, which was
determined in step 1 to be in disconnected status when the host was
started, is restored automatically, and the status changes to online.

.
Refer to /var/opt/DynamicLinkManager/log/dlmcfgmgr1.log or
execute the dlmcfgmgr utility (dlmcfgmgr -v) to check if the path to the
relevant HDLM device is restored.
The following is an example of executing the dlmcfgmgr utility:
# /sbin/dlmcfgmgr -v
Restoring the Path of an HDLM Device Started in Disconnected Status (When a
Restart Is Not Required)
This subsection describes how to restore the path to an HDLM device that was
in disconnected status (the cable was pulled out or broken) when the host
first started. In this method, the host is not restarted. Note that this
operation is applicable to the HDLM device managed by HDLM only. Also note
that the target path of restoration can be a single, multiple, or all path to the
HDLM device.
To restore the path of an HDLM device started in disconnected status
(this procedure does not restart the host):
1
.
Execute the HDLM-configuration definition utility (dlmcfgmgr -v) or the
view operation (dlnkmgr view -drv) of the HDLM command to check if
the host was started while the path to the relevant HDLM device was in
disconnected status.
The following are examples of executing the command or utility:
When executing the dlmcfgmgr utility with the -v option:
# /sbin/dlmcfgmgr -v
When executing the view operation with the -drv option:
# /opt/DynamicLinkManager/bin/dlnkmgr view -drv
If the SCSI device name mapped with the path to the relevant HDLM
device is represented with a hyphen (-), in the execution result, this
means that the path was in disconnected status.
Perform this operation if necessary. If it is not necessary to check this, go
to step 2.
