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 4-4
Add SCSI Devices on page 4-47 : 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
Changing an HDLM device name
This subsection describes how to change HDLM device names.
An HDLM device name is assigned depending on the HDLM specifications
when dlmcfgmgr is executed the first time after the OS recognizes a new LU.
You can execute the HDLM device name replacement utility (dlmchname) to
