I presume you mean "file system" (your subject line says "system file")?

1. Yes. You need to know which volume groups these logical volumes belong to (looking at the names, I would guess qa2vg).

Code:

lslv sapdata5qa
lslv ... etc for each

Run lsvg <volume group name>. Perhaps the space you need is already available.

Code:

lsvg $(lsvg) | grep -E "VOLUME|FREE"

2. Use chfs to add space to a filesystem

Code:

chfs -a size=+X ...
chfs -a size=X

where +X is to increase by an amount (like +1G, +100M, etc. and =X is to increase it to X (like =1G, 100M, etc.). Read the man page for chfs.

3. Have the disks been added? Did you run cfgmgr, then have a look with lspv. You should change the healthcheck interval to 60 using chdev. Extend the volume group(s) with the new disk(s). Read man extendvg. You may need to run chlv -x to increase the maximum LV's for the logical volumes. If chfs fails because of that, it will tell you what the value should be. Are the logical volumes striped (lslv will show this.)?

4. df -g should be sufficient.

fdformat

FDFORMAT(8)						     Linux Programmer's Manual						       FDFORMAT(8)

NAME

       fdformat - Low-level formats a floppy disk

SYNOPSIS

       fdformat [-n] device

DESCRIPTION

       fdformat  does  a  low  level  format on a floppy disk.	device is usually one of the following (for floppy devices, the major = 2, and the
       minor is shown for informational purposes only):

	      /dev/fd0d360  (minor = 4)
	      /dev/fd0h1200 (minor = 8)
	      /dev/fd0D360  (minor = 12)
	      /dev/fd0H360  (minor = 12)
	      /dev/fd0D720  (minor = 16)
	      /dev/fd0H720  (minor = 16)
	      /dev/fd0h360  (minor = 20)
	      /dev/fd0h720  (minor = 24)
	      /dev/fd0H1440 (minor = 28)

	      /dev/fd1d360  (minor = 5)
	      /dev/fd1h1200 (minor = 9)
	      /dev/fd1D360  (minor = 13)
	      /dev/fd1H360  (minor = 13)
	      /dev/fd1D720  (minor = 17)
	      /dev/fd1H720  (minor = 17)
	      /dev/fd1h360  (minor = 21)
	      /dev/fd1h720  (minor = 25)
	      /dev/fd1H1440 (minor = 29)

       The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for-
       mat has not been autodetected earlier.  In this case, use setfdprm(8) to load the disk parameters.

OPTIONS

       -n     No verify.  This option will disable the verification that is performed after the format.
