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
Add SCSI Devices on page
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
About Creating a New HDLM Device
While restarting the host, HDLM may detect a new path. The HDLM device to
be allocated depends on whether the SCSI device for the detected path is
already registered or a new SCSI device is registered. This section describes
a situation where the HDLM device that is to be allocated to the newly
HDLM Operation
