information) before the HBAs were replaced remains, this information will be
deleted when step 8 is performed.
8. Execute the
dlmcfgmgr
utility (
dlmcfgmgr -u
) to delete the information about
the old paths and SCSI devices.
In the
-u
parameter, specify an
HDevName
device for which old SCSI device
information is displayed in step 9. Note that you need to execute the utility for
each
HDevName
device that contains old SCSI device information.
The following shows an example of the command you execute if the
HDevName
value is
/dev/sddlmaa
:
# dlmcfgmgr -u /dev/sddlmaa
9. Execute the
view
operation of the
dlnkmgr
command (
dlnkmgr view -path
-hbaportwwn
) to confirm that all the old information for the paths that were
placed in
Offline(C)
status has been deleted.
# /opt/DynamicLinkManager/bin/dlnkmgr view -path -hbaportwwn
10. Execute the
dlmcfgmgr
utility (
dlmcfgmgr -v
) to confirm that all the old SCSI
device information has been deleted.
# dlmcfgmgr -v
HBA replacement has been completed.
If you have restarted the host after HBA replacement, update the path information
as described in (3) Updating the path information after the host is restarted.
(3) Updating the path information after the host is restarted
When the host is restarted after HBA replacement, the host port numbers in the HCTL
information are set again. As a result, the information about the paths that existed when
HBAs were replaced is now old, causing the old paths to remain in
Offline(E)
status. To correct this, use the following procedure to delete the old path information:
1.
Execute the
view
operation of the
dlnkmgr
command (
dlnkmgr view -path
-hbaportwwn
) to check the path status.
