RAID

Some quick notes on the RAIDS. This needs expanding.

The documentation for the controller should be available in /usr/local/doc/3dm2. There should be a deamon running, start it with "/etc/init.d/3dm2 start" With the deamon running, the device can be checked and manipulated using a web browser on the local machine pointing to http://localhost:888/. Log in as administrator with the root password.

More recently (2006) we no longer run this deamon, instead the RAIDS can be querried and controlled with tw_cli, in /usr/local/bin. Type tw_cli help for help. You must be root to run this program.

Examples (must be root):

tw_cli help info
tw_cli info c0     # info for card 0
tw_cli info c0 u0    # info for unit 0, Tells you it is RAID-5, Status OK, size, Stripe size
tw_cli info c0 p0  # info on disk0 on card0, size, serial number.
tw_cli info c0 p0 model # model number of disk (Maxtor 6B200S0)

Be totally wicked careful with any of the other commands PLEASE
