4. Refer to
/var/opt/DynamicLinkManager/log/dlmcfgmgr1.log
or
execute the
dlmcfgmgr
utility (
dlmcfgmgr -v
) or the view operation
(
dlnkmgr view -path
) of the HDLM command to make sure that the relevant
device is now managed by HDLM.
The following is an example of executing the
dlmcfgmgr
utility:
# /sbin/dlmcfgmgr -v
(8) Restoring the Path of an HDLM Device Started in Disconnected Status (When
a Restart Is 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 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.
To restore the path of an HDLM device started in disconnected status (this procedure
restarts the host):
1.
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.
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.
