I know I have posted this question before, but I still just don't understand how to determine disk space. This server is an IBM RS6000 running on AIX version 4.2.1.

I in essence need to know the following if anyone can assist me.

1) I need to know how many drives are configured in the server.
2) I need to know how to read the output from the command
df and then df -k The results are different.

df command produces the following:
Filesystem 512-blocks Free %Used Iused %Iused Mounted On
/dev/hd4 65536 30168 54% 1422 9% /
/dev/hd2 1785856 421888 77% 28840 13% /usr
/dev/hd9var 573440 114960 80% 2692 4% /var
/dev/hd3 2097152 2026656 4% 84 1% /tmp
/dev/hd1 196608 37072 82% 3821 16% /home
/dev/lv00 901120 199488 78% 4546 5% /apps
/dev/lv02 12222464 669136 95% 14938 1% /appsdata

When using the df -k command, the results are basically the same, except the sizes are half of the above output.

/dev/hd4 32768 15084 54% 1422 9% /
/dev/hd2 892928 210944 77% 28840 13% /usr
/dev/hd9var 286720 57480 80% 2692 4% /var
/dev/hd3 1048576 1013332 4% 84 1% /tmp
/dev/hd1 98304 18536 82% 3821 16% /home
/dev/lv00 450560 99724 78% 4546 5% /apps
/dev/lv02 6111232 334568 95% 14938 1% /appsdata


I am needing to add additional disc drives to this server. I also need to find out how the drives are currently mirrored... I know I need to get an AIX O/S handbook, Just trying to figure this out right now. Thanks for your help.
