How do I add a partition to AIX 4.3?

[JohnLynn]

I just recieved a Model R50. It has 2 18gig drives mirrored (I think). I would like to add a partition called "/u".

1. Recommenadation on how to procede.

2. Recommendations for a AIX Server Hardware Management book?

3. Is there a REAL paper manual to read? ( We recieved hundreds of CDs in the developer package. No joke. Just would like a place to start to I may RTFM. )

Thanks for the look.

I would not add a partition called "/u" this is a link to /home on AIX.

Also, you can check to see if rootvg is mirrored my using `lsvg -l rootvg` and check the LP and PP columns to see if it is doubled, if it is then it is mirrored.

they are all right.also, you can download the administration book for AIX if you want to read more about it. This is very informative to begin with.

Hi,

in version 3 of aix, home filesystem was mounted under /u.

For back compatibility, or whit other unix, some applications stores data under /u/....
As AIXSPadmin has alreadey indicated, in AIX 4, there is a link between /u and /home.
If the data that the application stores are few, don't do
anything, leave that a directory (as MyAppl) is created,
under home.
If data are a lot, is better if you create a filesystem nemed /home/MyAppl (just an example), and yor application
will create files in a not standard JFS.

(When you will remove these data, you can remove this jfs,
instead to have to reduce /home, that is not immediate)

Ciao.

While you are downloading the redbooks, here are some LVM commands to do a man on:

lsvg
lspv
lslv

You will have to use all three commands with various switches (mostly -l and -p) and stare at the screen for quite some time but you will figure it out eventually.

If you are going to add some data filesystems I suggest creating a new volume group on disks other than the two (I assume) in rootvg.

To see if rootvg is mirrored:
#lsvg -l rootvg
Look to see if 2*LP=PP, if so you are mirrored. IBM Certified -- AIX 4.3 Obfuscation
