Thanks for the reply guys.....
Below is how my system is partitioned.
# df -v
Mount Dir Filesystem blocks used avail %used
/ /dev/root 6291456 2804708 3486748 45%
/stand /dev/stand 122880 10688 112192 9%
/proc /proc 0 0 0 0%
/dev/fd /dev/fd 0 0 0 0%
/dev/_tcp /dev/_tcp 0 0 0 0%
/home /dev/dsk/c0b0t0d0s4 3440640 498720 2941920 15%

The database is on /raid mount.
The server has got about 130 users connecting to it.
The performance is fine, no problems with that.
We are having problems with backups and not getting the throughput that we should. IBM Had come and tested and replaced hardware but still no fix.
We are using a Ultruim LTO 3 drive and we are getting 6.4MB/s data transfer rate.

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. SEE ALSO
