Hydra

A hydra

A Sun Fire T2000, 6-core 1.0GHz UltraSPARC T1, 8GB RAM. It's on evaluation; not ours yet. IP 10.0.0.201. Runs Solaris 10.

ALOM: connect to port 'hydra' on the SCS. Type #. to enter the ALOM console, 'console' from there to enter the system console. From Solaris type ESC-B to enter the openboot prompt. Type 'go' to get back to Solaris.

Useful ALOM commands at the sc> prompt:

poweron
poweroff
powercycle

It has two drives with all FSs mirrored. If the primary drive fails then 'boot backup_root' from the prom (it should do this automatically).

Don't use GCC to compile things here (it's slow on SPARC). Use cc (or CC for C++) in /opt/SUNWspro/bin.
