Restoring the path in disconnected status

This subsection describes how to restore the path to an HDLM device that was in disconnected status (the cable was pulled out or broken).

1. Execute the HDLM-configuration definition utility (dlmcfgmgr -v) to check while the path to the relevant HDLM device was in disconnected status.

   The following are examples of executing the command:

   # /sbin/dlmcfgmgr -v

   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.

2. Connect the cable.

   If the cable is broken, replace it.

   When the restart of the host is possible, go to step 3. When the restart of the host is not possible, go to step 4.

3. Restart the host.

   The SCSI device is recreated, and the status changes to online. Go to step 6.

4. Create the SCSI device for the path to be restored.

   You must execute the command for adding a device, shown in Table 1: Add SCSI Devices, to manually create the SCSI device.

5. Wait until the automatic failback function starts, or execute the dlnkmgr command (dlnkmgr online -pathid AutoPATH_ID).

   The following is an example of executing the HDLM command:

   # /opt/DynamicLinkManager/bin/dlnkmgr online -pathid AutoPATH_ID

   The relevant path is placed online.

6. 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
