disk layout on Unix

[thedba]

On Nt, I know that when you go through:
START-PROGRAMS-WINDOWS NT EXPLORER, you can see the disk layout C,D,E,F,G,H,I,etc. How do you look for the disk layout on a UNIX platform

[pwoneill]

type "df", or "df -k" for a slightly more understandable output.

each of the paths listed there are a mounted partition of a disk. if you're on a sun, the disk names will be the things that look like c0t0d0s0.

The c is for controller number
t for target number
d for disk number
s for slice (partition) number

A disk with 2 partitions might have two entries like this

c0t0d0s0 /usr -- rest info
d0t0d0s1 /usr/local -- rest of info

What if the unix flavor is AIX, is it going to be the same layout like you just explained or slightly different?

beats me, type df and find out :) it will probablly be something similar if not exactly the same, but i really cant' say because i haven't used AIX.

on AIX.

lsvg : list of all volume groups
lsvg <vg> : info about a volume group
lsvg -l <vg>: list of all logical volumes in a volume group
lsvg -p <vg>: list of all physical volumes in a volume group

df : list of all mounted(!) filesystems
gives following info
Filesystem device name
512-blocks total number of 512-byte blocks
Free free blocks
%Used % off blocks used
Iused number of inodes used
%Iused % off inodes used
Mounted on mount point of filesystem
or use df -k to have info in Kbytes


Hope this helps
