extend vg00

Hi,

 

I am currently running hpux 11iv3 on a bl890 attach to a P6000, I need to increase the vg00 since it was configure by HP a little short.  So, I did increase the lun on the P6000, thinking that I would be able to use vgmodify, but it was configured with version 1.0, how can I do this?

 

When I run vgmodify I get this error:  vgmodify: Error:Cannot use -a with a version 1.0 root volume group

 

 

Thanks,

Re: extend vg00

Making a LUN bigger is a very new concept. It is far easier to simply create another LUN from your storage and just vgextend vg00 with the new LUN. The new LUN should be the same size or smaller than the first LUN. The steps are:

 

-- allocate a new LUN and present it from your storage

-- ioscan -fCdisk (to find the new LUN)

-- insf -eCdisk (to create the new device files)

-- ls -lrt /dev/disk (to see the new device file name at the bottom with today's date)

-- diskinfo /dev/rdisk/disk...  (to verify functionality and see the size of the new LUN)

-- pvcreate /dev/disk/disk... (to prep the disk for use in LVM)

-- vgextend vg00 /dev/disk/disk... (to add the LUN to vg00)

-- vgextend vg00 (to see the new unused extents)

 

And you're ready to use the additional space.

"Online vgmodify is supported starting with the HP-UX 11i v3 September 2008 Update release."

 

 

What is your OS core version?


Hope this helps!

Re: extend vg00

Hi,

 

I am running the most recent version of the o/s March 2012 release.  Like I mentioned the o/s was install by HP services, the vg00 have been installed with version 1.0 instead of 2.2.  Since this is a boot drive, I can not use vgversion to increase the version to 2.2.  Is there a way even offline to use DLE with vg00?

 

Worst case, I will present new lun, but would like to stick with only 1 lun for vg00.

 

Thanks,

Torsten.

How about LVM maintenance mode?

Hope this helps!

Re: extend vg00

Sorry, it is not supported for boot volumes.

Consider to do an ignite backup and restore to a version 2.2. VG.

Hope this helps!

Re: extend vg00

What vgmodify command did you run?

Something like

# vgmodify -v –r –a –E vg0

Hope this helps!
