How to increase Virtual Disk size

UNIX AIX
1

Hello,

I am working AIX VIO server and extended Virtual Disk of one of the Partition with 10GB. After starting partition, i am not able to see increased size of disk.
Can you please help me what I need to do to increase the size of virtual disk from partition?

Thanks

Yes you will have to unmap the disk and remap it back to the Lpar

if the Lpar is up you may have to export the vg (not rootvg )
Unmap the disk in the vioserver ( rmdev -dev device_name )
remap the disk to the vhost (mkvdev -dev bla bla )
on the host ( cfgmgr )
re inmport the vg

check the disk size ( bootinfo -s hdiskxx )

I have AIX 6.1 installed on this rootvg. will rmdev -dev device_name will remove data or affect to my existing AIX6.1 installation?

without above steps bootinfo -s hdisk0 is showing extended space, which i wanted to see. But through lspv hdisk0 it is still showing less 10 GB.

# bootinfo -s hdisk0
33792

# lspv hdisk0
PHYSICAL VOLUME: hdisk0 VOLUME GROUP: rootvg
PV IDENTIFIER: 0006a8815e7dbc31 VG IDENTIFIER 0006a8810000d600000001215e7dbcf2
PV STATE: active
STALE PARTITIONS: 0 ALLOCATABLE: yes
PP SIZE: 128 megabyte(s) LOGICAL VOLUMES: 13
TOTAL PPs: 183 (23424 megabytes) VG DESCRIPTORS: 2
FREE PPs: 0 (0 megabytes) HOT SPARE: no
USED PPs: 183 (23424 megabytes) MAX REQUEST: 256 kilobytes
FREE DISTRIBUTION: 00..00..00..00..00
USED DISTRIBUTION: 37..37..36..36..37

Now then you use

chvg -G vgname

This will pick up the changes

for normal vgs, you don't have to remap a disk to the lpar, just use chvg -g vgname
that works since vio 1.4 I think, before it was necessary to remap the lun

since it's rootvg, you have a problem, because chvg -g rootvg is not supported

the easiest way is to map a new bigger disk, and use migratepv hdisk0 hdiskx

or mirrorvg and unmirrorvg

edit:

as I wrote, this is

  1. not supported
    and
  2. wrong, because -G changes the vg format to scalable

try varyongvg rootvg without any flag.

I got below msg.

# chvg -g rootvg
0516-1380 chvg: Re-sizing of the disks is not supported for the rootvg.
0516-732 chvg: Unable to change volume group rootvg.

I guess now I have only one option and that to add new disk with big size and migrate the vg.

I didn't get that, which command you want me to execute?

Did you tried to reboot the Partition?if no its wise to reboot....

After reboot if the size doesnt came then you can try below command.

"varyongvg rootvg"
