Example entries are shown below.
When adding a device by using a QLogic HBA driver in Red Hat Enterprise
Linux AS4/ES4:
# echo "scsi-qlascan" > /proc/scsi/qla2200/1
# cat /proc/scsi/qla2200/1
# echo "scsi add-single-device 1 0 1 1" > /proc/scsi/scsi
4.
Execute the HDLM-configuration definition utility (
dlmcfgmgr -r
).
Based on the SCSI device created in step 3, an HDLM device for the path
configured in step 1 is added.
The following is an example of executing the
dlmcfgmgr
utility:
# /sbin/dlmcfgmgr -r
5.
Restart the host on which the HDLM is installed.
If you performed step 3 and step 4, the host does not have to be restarted. Go to
step 6.
While restarting, the HDLM device mapped with the path configured in the above
step 1 is added automatically.
6.
Refer to
/var/opt/DynamicLinkManager/log/dlmcfgmgr1.log
or
execute the
dlmcfgmgr
utility (
dlmcfgmgr -v
) to check if an LU was created
with a new HDLM device name.
Deleting a device
(for FC-SAN
environments)
# dlmcfgmgr -o logical-device-file-name-of-the-relevant-HDLM-device
# echo "scsi remove-single-device
a

d
" > /proc/scsi/scsi
# dlmcfgmgr -i logical-device-file-name-of-the-relevant-HDLM-device
Deleting a device
(for IP-SAN
environments)
# echo "scsi remove-single-device
