UNIX for Dummies Questions & Answers

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

As I understand this, I'm thinking that this is a raid 5 setup. Can anyone confirm this for me?
