regarding raid
Hello, I am aware that our system has two hard drives with raid but i'm not sure as to the type of raid the system uses.
I tried this.
# df
Filesystem 512-blocks Free %Used Iused %Iused Mounted on
/dev/hd4 229376 76272 67% 6748 12% /
/dev/hd2 3080192 1136120 64% 19957 6% /usr
/dev/hd9var 983040 778064 21% 391 1% /var
/dev/hd3 360448 65160 82% 3989 9% /tmp
/dev/hd1 32768 31608 4% 40 1% /home
/dev/lv00 1048576 374784 65% 8600 7% /PRISM
/dev/lv01 8388608 3260584 62% 3244 1% /SDI00
/dev/lv02 262144 201128 24% 138 1% /SDF
/dev/lv03 262144 205752 22% 849 3% /iq
/dev/lv04 22806528 10892176 53% 55192 2% /SDI02
Does this mean there are 5 partitions? Am I on the right track, or a complete loss lol. Any help is welcome. Thanks

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.
