relevant HDLM device is restored.
The following is an example of executing the

dlmcfgmgr

utility:

# /sbin/dlmcfgmgr -v

(9) Restoring the Path of an HDLM Device Started in Disconnected Status (When

a Restart Is Not 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 not restarted. Note that this operation is applicable to the

HDLM device managed by HDLM only. Also note that the target path of restoration

can be a single, multiple, or all path to the HDLM device.
To restore the path of an HDLM device started in disconnected status (this procedure

does not restart the host):
1.

Execute the HDLM-configuration definition utility (

dlmcfgmgr -v

) or the

view

operation (

dlnkmgr view -drv

) of the HDLM 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.

Create the SCSI device for the path to be restored.
Since you restore the path without restarting, the path for the SCSI device which

was in disconnected status during bootup will not be created and you must

execute the command for adding a device, shown in Table 4-4: Add SCSI

Devices, to manually create the SCSI device.
