RISC/6000 - AIX 4.3 system administration - Fundamental doubts

[agn76aix]

Hi all,

I am a new RISC/6000 - AIX 4.3 system administrator. I am new into AIX System Administration. Inorder to learn more about my systems, I would like to get valuable help from you.

a) How can I know how many physical hard disks are there.
b) What are the previous boot date and time of my machine.( To know how stable the system was in previous days and to know how often I may need a physical rebooting)
c) is there any Mirroring/Cloning/Clustering done on the system, if so, which is the backup copy.

Expecting your reply

AGN

a) execute "lspv" command
b) execute "last reboot|head"
c) Mirroring:
LVM provides mirroring capabilities, but is a topic very
very long to discuss in a single post
Cloning:
mksysb command (executed in the correct way) provides a
perfect system copy useful for cloning, obviuosly HW
should be the same or very similar between the master
and the clone
Clustering:
HACMP provides a various range of cluster configuration,
but it's another very very long topic to discuss in a
single post

Hi agn76aix,
Following hints:
a) lspv
b) who -b
c) lsvg gives the volume groups known by AIX
lsvg -o volume groups which are online
lsvg -l <vg name> lists all logical volumes belonging
to that vg and also shows their attributes.
if PPs = LPs * 2 (or 3) LV normally is mirrored
lslv <LV name> will give you detailed information on a
logical volume, e.g. number of copies

And, if you are new to AIX, go to

http://www.redbooks.ibm.com,

search on 'AIX AND certification' and download the certification study guide for system admin. it tells you just about everything you will need to know on a day to day basis.

And there is an FAQ (faq52-2441) that has a script that gives you a report on what disks you have, what's on them, and how much room is taken and remaining.
