To restore the path of an HDLM device started in disconnected status (this procedure restarts the host):
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 restarted. Note that this operation is applicable to an HDLM device managed by HDLM only. Also note that the target path of restoration can be a single, multiple, or all paths to the relevant HDLM device.
Execute the HDLM-configuration definition utility (dlmcfgmgr -v) or the view operation (dlnkmgr view -drv) of the dlnkmgr 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.
Connect the cable.
If the cable is broken, replace it.
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
