LVM clueless on a 12H Raid controller

[BoB Yeska]

I've just added 3 new LUN's to the disk array. What I want to do is add 2 Lun's to vg02 and vg03. Each of these vg's have only one lv. I'd like to double the capacity of the vg/lv by assigning one of the new Luns to each vg. Under vg should I use the expand option in SAM or modify VG or should I skip the whole thing and go to the lvm like I would in Smit (AIX)?

You will need to do a vgextend for each volume group (vg02, vg03) to add the lun to the volume groups. Then you will need to do an lvextend to increase the size of the logical volumes.

You can probably do all of this through SAM if you want to.

You need to do vgextend first and then lvextend later but if you don't have OnlineJFS installed on the system, you have to do unmount file systems associated for extendfs to work.
You can do this with fsadm online if OnlineJFS has been installed.

Best regards,
