What command syntax > would I use to mount the second disk? after booting from cdrom, # mkdir /tmp/foobar # mount /dev/dsk/c1t3d0s0 /tmp/foobar (obviously the c1t3d0s0 would be replaced by whatever is the controller/scid id and slice of your second disk. That sort of information is worth storing on a bit of paper, or another computer so you know what). I'm assuming your SPARC box is a SCSI based on. If its IDE (Blade 100 and similar), the device file will be a bit different. Just run 'df' before you get problems, so you know what each slice does. Dave |
