Mounting drives

[Aaron1940]

Hello all,

I am a novice user to the unix world.
Can someone assist me with mounting drives.
I just had two harddrives installed on the RS/6000, but now I need to make them useable

hdisk0 000dc0ade656387d rootvg
hdisk1 000dc0adfeed08dd fegsdata
hdisk2 none None
hdisk3 none None

Please assist.

Are they going to be a part of fegsdata volume group?
If so, then:
extendvg fegsdata hdisk2
extendvg fegsdata hdisk3

Then, create your logical volumes, filesystems, etc.

Otherwise, you will need to create a volume group and add hdisk2&3 to the new volume group:
mkvg -f -y'testvg' hdisk2

Welcome to the wonderful world of the Logical Volume Manager. =)

Just so you are not confused like I was when I started, physical disk are grouped into volume groups, or vg. Your various vg are then divided into logical volumes of various sizes. These are analogous to a physical disk on other systems, the convenience being that they can be any size. Inside lv you make filesystems, and the fs are analogous to a DOS partition. Normally you would just make your fs take up the entire lv.

LVM is a great tool, just has a bit of a learning curve if you are not used to the ideas. IBM Certified -- AIX 4.3 Obfuscation
