Execute the utility for clearing HDLM persistent reservation (dlmpr) to
clear the reservation of LUs comprising the applicable volume group:
# /usr/DynamicLinkManager/bin/dlmpr -c hdisk-name hdisk-
name ...
h
.

group:
# varyonvg volume-group-name

After you replace an HBA, any paths that go through that HBA might be
removed (due to AIX specifications) from the paths to a specified boot
disk hdisk (logical device file), which will no longer be recognized as the
boot disk. If this happens, it is necessary to restart the host, and then re-
specify the path that goes through the replaced HBA as a path to the boot
disk, as shown in the procedure below.
To re-specify a device called hdisk10 on the storage system as a boot
disk:
a
.
Execute the following command to restart the host:
# shutdown -Fr
b
.
Make sure that the boot disk is in a multi-path configuration:
# lspath -l hdisk10 -s available
Available hdisk10 fscsi0
Available hdisk10 fscsi1
...
c
.
Check the current boot disk list:
# bootlist -m normal -o
hdisk10 blv=hd5
hdisk0 blv=hd5
hdisk1 blv=hd5
...
d
.
Specify boot disks that are suitable for your host environment:
# bootlist -m normal hdisk10 hdisk0 hdisk1
e
.
Make sure that the number of configured boot disks is the same as
the number of paths that you checked in step 2:
# bootlist -m normal -o
hdisk10 blv=hd5
hdisk10 blv=hd5
hdisk0 blv=hd5
hdisk1 blv=hd5
