[comp.unix.ultrix] 3rd party disks on uVAX2000 ?

rizzo@uicsl.csl.uiuc.edu (10/01/90)

Once again, I'm looking for help from the network that knows everithing.

Given the high number of answers on the use of 3rd party disks
on DEC machines, does anyone use 3rd party disks on a
microVAX 2000 ?  What I'd like to know is whether I'm limited to 150MB disks,
as the RD54 is, or there are other, larger disks that I can connect to
the back connector of my microVAX 2000 ? Do I need special device
drivers ?

	Thanks

If the 3rd party drive conforms to DSA (Digital Storage Architecture), then
The disk should be able to act as a data disk for your VS2000.  The drive
should come with a manual describing the track and sector information.  With
this, you will need to create an entry in /etc/disktab (assuming it's not there
already).  Once this is done, you should be able to newfs(8) a filesystem
on the new disk that will use the extra available space.  You should not
need any special device drivers.  The disk driver in ULTRIX reads the disk's
configuration information off the super block at boot time.
