Have you ever wanted to change packs -- like on an RM03 -- while your system was up, running off a different pack. Well, I did today, and was desperate to try anything.... This is what I came up with. Problem: If you've tried this (with V7 or 2.8, I haven't tried with 2.9) you've noticed it doesn't work. As soon as the pack is changed, the system refuses to recognize the drive. Solution: I have that Remote Diag console, so I halted the machine (while the machine was running, in single mode by the way) and issued a controller-clear to the controller, in my case, the RM03. I then continued the processor and returned to user-mode. From this point on, the drive worked fine. Question: Any idea why a controller-clear isn't done when things seem hopelessly screwed up? I plan on checking out the 2.9 driver asap to see if it does this or not. -- Dave Cohrs @ wisconsin ...!{allegra,heurikon,ihnp4,seismo,sfwin,ucbvax,uwm-evax}!uwvax!dave dave@wisc-rsch.arpa
