chvg -g VGName

hirschaj:

Thanks for your help, i found in another place this information:

...then increased the capacity through Storage Manager on the FAStT device by adding another disk. I got the message as above, but went ahead
and added the disk. Once it completed, on the AIX host, I ran;

cfgmgr - it indicated an hdisk had increased in size...

chvg -g testvg - examine all disks in the vg to see if they have
grown and attempt to add additional PPs to PV.
lspv hdiskn - showed the proper increase in size of the PV.


do you think is correct?


In another hand I searched on rootvg the command list and make a little brief about the chvg command, and make the note that maybe I will have to run the varyon and varyoff commands. in your experience, how offen occurs this?

Thanks again!!!

I have never had to run the chvg -g command. The list above looks fine to me. I would suspect that you will have to varyoff and varyon, but the system should let you know. I would not try to do this during normal production hours, and I would make sure to have good backups.

OK is fne for me.


Thanks for your help.

Good Luck!!

Hi, Did the steps above work out ok for you. I have to do exactly the same thing one one of my systems, but running AIX 5.2 ML6.

When I ran this procedure, it was no so easy as in the top descibres. I added the space on the DS4300, then I had to run the chvg -g command and nothing happens. So... try after the chvg command, with the varyoff and varyon commands, it should be OK.
