7.
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
...
8.
Execute the following command to activate the applicable volume 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:
1.
Execute the following command to restart the host:
# shutdown -Fr
2.
Make sure that the boot disk is in a multi-path configuration:
# lspath -l hdisk10 -s available
Available hdisk10 fscsi0
Available hdisk10 fscsi1
...
3.
Check the current boot disk list:
# bootlist -m normal -o
hdisk10 blv=hd5
hdisk0 blv=hd5
hdisk1 blv=hd5
...
4.
Specify boot disks that are suitable for your host environment:
# bootlist -m normal hdisk10 hdisk0 hdisk1
5.
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
