[net.unix-wizards] problem with 2 disks on an SC21 controller

chris@grkermit.UUCP (Chris Hibbert) (06/20/83)

(I thought I had posted something on this subject a while back but I've
gotten absolutely no response, so I'm trying again.)


I currently have a VAX 11/780 running 4.1BSD with an emulex SC21
controller handling one 300M disk.  I have been trying for the last few
months to get the controller to handle a second disk.  

The usual symptoms are normal operation if only one of the disks is
connected.  If they are both connected, then I get hard error messages
whenever I try to access either disk.

Does anyone have any experience (either successful or unsuccessful)
with trying to get an SC21 to handle two 300M disks?

Please reply directly to me.
