AIX 6.1 Native SAN from VIO to LPAR- How to Remove
This example is removing the mapping from VIO to LPAR that is being decommissioned.
Access LPAR to determine the mapping information:
[root@ret4a139v:~] # lsvg
rootvg
From this output we see there is only one volume group called rootvg. Below we will list the logical volumes inside the rootvg volume group and see how they are mounted.
[root@ret4a139v:~] # lsvg -l rootvg
rootvg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
hd5 boot 1 1 1 closed/syncd N/A

Now we can remove the mount points and logical volumes using rmfs command:
#for i in /opt/openv /opt/Tivoli /opt/esm /mksysb_dir /usr/local /root /var/adm/ras/livedump /opt /admin /tmp /var /usr /home; do rmfs -r $i; done
At this point we need to find out the vscsi slot number to identify the vhost on the VIO server. We will list the adapters then show the config for the vscsi on the LPAR. Then take the slot number and find the vhost on the VIO server on the same slot.
From the LPAR:
[root@ret4a139v:~] # lsdev -c adapter

[root@ret4a139v:~] # lscfg -l vscsi1
vscsi1 U9117.MMB.1010F9P-V9-C54-T1 Virtual SCSI Client Adapter
As padmin on the VIO server:
padmin@retvio187a1:/home/padmin $ lsmap -all | grep -i c53
vhost16 U9117.MMB.1010F9P-V1-C53 0x00000009
Alternatively, we can also use the below command:
padmin@retvio187a1:/home/padmin $ lsdev -slots | grep -i c53
U9117.MMB.1010F9P-V1-C53 Virtual I/O Slot vhost16
padmin@retvio187a1:/home/padmin $ lsmap -vadapter vhost16

Now we can remove all virtual target devices associated with the given backing devices.
#for i in hdiskpower151 hdiskpower152 hdiskpower153;do rmvdev -f -vdev $i;done
