the device shown in Table 4-3 Adding or Deleting a SCSI Device on page
4-59 to manually delete the SCSI device.
5. Restart the host on which the HDLM is installed.
If you performed step 4, the host does not have to be restarted. Go to
step 6.
6. Execute the HDLM-configuration definition utility (dlmcfgmgr -v) or the
view operation of the dlnkmgr command (dlnkmgr view -drv)
(optional).
Check if the SCSI device name of the HDLM device whose path was
deleted in the above step 2 is represented with a hyphen (-).
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
Perform this operation if necessary. If it is not necessary to check this, go
to step 7.
If the SCSI device name is not represented with a hyphen (-), to change
the SCSI device name to a hyphen, wait until the path health checking
has been executed or execute the following dlnkmgr command with the
AutoPATH_ID of the HDLM device.
Example:
# /opt/DynamicLinkManager/bin/dlnkmgr online -pathid AutoPATH_ID
7. Execute the dlmcfgmgr utility (dlmcfgmgr -
ulogical_device_file_name_of_HDLM_device ) on the relevant HDLM
device whose path was deleted in the above step 2 to unregister the
HDLM device.
Path information on the relevant HDLM device is deleted.
The following is an example of executing the dlmcfgmgr utility:
# /sbin/dlmcfgmgr -u name-of-logical-device-file-for-HDLM-device
If you execute the dlmcfgmgr utility (dlmcfgmgr -u) when a path to the
HDLM device exists (for example, when you change a multi-path
configuration to a single-path configuration), the KAPL10340-E message
is output. In this case, take action according to this message and refer to
the /var/opt/DynamicLinkManager/log/dlmcfgmgrn.log file (where n is
1 or 2). If the KAPL10362-W message was output to the /var/opt/
DynamicLinkManager/log/dlmcfgmgrn.log file, HDLM operations are not
affected. Go to step 8.
