[SunRescue] Extra HD

[ed_mitchell at adc.comed_mitchell]

The Sun disk naming conventions can be helpful when dealing with large
numbers of disks.  Read properly, they will pretty much lead you to the one
dead disk in the 26 drive array. ;) (especially when the frickin Veritas
tools don't work right).

Got this working! I needed the device name but found it in /dev/dsk. It was
c0t1d0s0. Sheesh /dev/hdb1 seems so much simplier. The drvconfig also made
the VGA frame buffer I got work with X. Thanx everyone for the help.

Next question....The ISDN interface on the ss10. Where would one set SPIDs
and such? Does the system treat this like a serial port? Has anyone ever
used this with pppd to get an Internet connection?
