We just lost a Fujitsu 2333 disk drive on our Sun 3/260 with
xylogics 450/451 controller. I want to replace it with a newer,
larger capacity drive. I can get a good price on the CDC Sabre
series drive (nominally 800 megabytes). It's a standard SMD
drive, and it looks like it should fit in the pedestal in place
of the Fujitsu drive. I think I can stretch the cables to the
connectors on the CDC drive. I'll probably have to rig a
substitute power cable.
Has anybody had experience with this drive on a Sun, and can you
give me some hints on formatting it and getting it running?

It's a standard SMD # # @(#)format.dat 1.4 87/11/20 SMI # disk_type = "CDC 9720-850" \ : ctlr = XY450 : fmt_time = 4 \ : ncyl = 1378 : acyl = 3 : pcyl = 1381 : nhead = 15 : nsect = 67 \ : rpm = 3600 : bps = 603 \ : bpt = 40401 : drive_type = 1 you must have the drives you can turn off the runt sector for this.

So swapping them, a priori, should not be a problem, as long as you have the mounting hardware - a special bracket - that holds the disk to the internal skeleton of the pedestal. The 'diag' program should have a label already for a CDC, but if not, you'll have to go the 'other' route and generate a lable by hand. Don't worry about it until you have to. Reading disk drive manuals is a great way to catch up on your sleep. The one trick I ran into here was power cable, as you noted. Sun's got a little PC board with a few resistors in it and such that does the job. If you're on good terms with your FE, you might be able to get one from her unofficially. Otherwise, you have to figure out the differences between power leads for the two disks yourself and make your own adapter. If you've got one to look at, it'd help you a lot, you might want to look for other CDCs in your Sun farm. > Mike Berger > Department of Statistics, University of Illinois -- richard -- * Tyger, tyger, burning bright, ..{amdahl,decwrl,hoptoad,hplabs, * * In the forest of the night ; octopus,pyramid,ucbvax,vixie} * * What immortal hand or eye, !avsd.UUCP!childers@tycho * * Could frame thy fearful symmetry ?
