VIOS: Extend virtual disk assigned to running lpar?
Hello,
VIOS 2.2.1.4 using IVM.
I'm trying to extend a virtual disk assigned to a running lpar so that I can expand the lpar's datavg and grow some filesystems for the user.
Storage admin expanded the lun and new size was reflected in VIO right away. I then needed the storage pool to reflect the new size which I accomplished using:
With storage pool showing new free space, I was looking for a command to extend the virtual disk assigned to the storage pool, which I had no luck. Instead I tried using IVM to extend the virtual disk, however I got a warning about the virtual disk assigned to a running partition.
You will either need to restart the partition after extending the size, or reconfigure the device using the partition's operating system. If you would like to proceed anyway, select the checkbox below, and select OK again. Force extend on running partition.
I'd like to attempt this without shutting down the lpar, however I can't risk a production outage either. Does anyone know the implications of using the "Force extend" option?
I'm referring to the VIOS side. I need to get the VIO virtual disk expanded first, then from the lpar run
and verify the PV size changes with
Once those are accomplished, I can then expand the VG.

I was able to figure this out. Here are the steps for future reference.
This is for VIOS with logical volumes (virtual disks) based on storage pools.
1. Storage admin added 40gb to existing LUN.
2. Checked VIO for pv size increase
3. Checked VIO for vg size increase
4. Increase size of logical volume (virtual disk)
5. Next, checked lpar for pv increase
6. Checked lpar vg for size
7. Extend lpar vg
8. Recheck lpar vg for new size
This was all done using command line; no need to restart the lpar. I checked within IVM just for reference.
Hello,
In my environment, I have 2 VIOS. There is 1 lpar uses the first VIOS. Now we would like to move it to second VIOS.
My question is, can we migrate the virtual FC on the lpar to second VIOS?
If not, we have to create new virtual FC on second VIOS and map it to the lpar. This also... (3 Replies)
Hi everybody,
I have Power5 server with 4 internal hdisks each of 70Gb.
VIOS server was installed via Virtual I/O Server Image Repository on the HMC.
HMC release - 7.7.0

Hi All,
Besides the licenses on VIO and LPAR. What's the main difference with the two? I have installed VIO, my manager told me so, because it's like a free hypervisor but I never installed LPAR before. How do you install it? And if you can give more info on the two, that would be great.

Hello,
I have created mapping of 2 virtual adapters for Lpars using following command:
mkvdev -vdev ipanalyzerlv1 -vadapter vhost11
mkvdev -vdev ipanalyzerlv -vadapter vhost13
The above two commands were succesfull
but when I want to map the third virtual device to the same Lpar than... (3 Replies)
I have a DUAL VIO ( IBM Virtual I/O ) setup on p 570.
Two Vio server ( VIOS ) and many LPAR clients.
VIO ( latest version + service pack + applied the fix ) and AIX 6.1 ML2
When both VIOs are running, and if I turn on a Client LPAR, the LPAR hangs at LED 25b3 for more than 1 hour then it... (2 Replies)
Hello guys,
It would be so nice of you if someone can provide me with these informations.
1) My SAN group assigned 51G of LUN space to the VIO server.I ran cfgdev to discover the newly added LUN. Unfortunately most of the disks that are in VIO server is 51G. How would I know which is the newly... (3 Replies)
Hi,
I define 2 new LV on the vio server and run a cfgmgr on the partition and see my 2 new hdisk (hdisk6 and hdisk7).
I extend my vg vg000 (on the partition) and add the 2 hdisks.
I had a filesystem on the vg000 and when I added the disk I would like to increase the filesystem. But I cannot do a... (0 Replies)
