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
TOMATO:
Contains a RAID with 12 Maxtor Diamond Max 10 drives (300GB, model number: 6B300S0). Data Sheet
Size: 300 GB Spin: 7200 RPM Buffer: 16 MB Seek: <9 ms Latency: 4.17 ms] Current/Power - not specified. 1.2 Amp/ 15 Watt is a good guess
GOURD:
Contains a RAID with 8 Maxtor drives (251GB, Model number 7Y250M0)
