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
