Manually Performing hdisk Reconfiguration

The procedure below explains how to manually reconfigure an hdisk.
Note:
In the procedure below, if you execute the dlmchpdattr utility without
performing either step 2 or 6, any changed values will not be applied, even
though the lsattr command execution results will show that the changed
values were applied. To apply the changed values, perform step 2, and then
perform step 10 for a local boot disk environment, or perform step 12 for a
boot disk environment.
To manually reconfigure an hdisk:
1 Log in to AIX as a user with root permissions.
.
Reconfigure the HDLM device. Proceed to step 2 to automatically perform
the processing needed to unmount for reconfiguration, and processing to
change the active status of the volume group. Proceed to step 3 to
perform these actions manually.
2 Execute the utility for deleting HDLM drivers (dlmrmdev) with the -e
.
parameter and -A parameter specified.
# /usr/DynamicLinkManager/bin/dlmrmdev -e -A
