SUMMARY: Disksuite metadb replicas on 3310 JBOD

Earlier this week I posted the following problem that I was having with
DiskSuite, a SUN280R & a 3310 JBOD. Sorry not to have posted a SUMMARY
earlier but I was only able to get access to the problem machine this
morning.

> card (controller).

> This I have done but with no effect. The replicas still go bad on a reboot.

I had:

 * 8 "Out of Office AutoReply" messages immediately. Irritating that even
   today some people don't stop these going to list servers!
   
 * One from "AntiSpam UOL" with an HTML email asking me to confirm my
   email! Even more irritating. AntiSpam + HTML email? This is someone
   with problems.
   
 * Helpful answers from;

   Thanks to you all, especially Paul Heydenrych.
   
   The problem was not that I had put metadb replicas on the external discs,
   nor that I had filesystems also on the same slices as the replicas. Also
   I did not want to restrict the replicas to the internal discs only since
   I wanted to use more than one controller.
   
   Paul Heydenrych had the correct answer. He suggested adding ALL the
   following to /etc/system;
   
   	forceload: drv/glm
   	forceload: drv/sd
   	forceload: drv/pcisch
   	forceload: drv/qlc
   	forceload: drv/fp
   	forceload: drv/ssd
   	
   and then rebooting, hopefully successfully. Then remove one line at a
   time and reboot until the system fails to come back up.
   
   In my case I already had;
   
   	forceload: drv/pcisch
   	forceload: drv/qlc
   	forceload: drv/fp
   	forceload: drv/ssd
   	
   in /etc/system from other installation needs. After only a couple of
   test cycles I established that the;
   
   	forceload: drv/sd
   	
   was the crucial line. Once I had added this everything started to work
   perfectly.
