The good news is some of the new disk space has arrived. The bad news is that I'll need to take down Kim, Gawd, Ernie and Icy for unspecified intervals at various times over the next few days. This is going to be a painful and time consuming process and take a great deal of cabling and re-cabling to get the whole thing to work. So you'll get a better feel for what I'm up against, here's what has to be done: Format and verify the new disks (in process 6-8, hours/drive). Shutdown Gawd and hookup the new drives to it, reboot. Dismount (logically) Kim's userdisk from the cluster. Mount Kim's userdisk and the new disks on Gawd only. copy all the files from kim to the new disks (should take about 3-4 hours). Mount the new disks on the cluster as KIM$USERDISK. Shutdown Kim and disconnect the 2 drives that were KIM$USERDISK. Adjust all hardware and software parameters indicating that Kim has only 1 disk and reboot. Format and verify these disks so they can be plugged into a different controller (6 hours/drive or so). Shutdown Ernie and hookup one of the newly formatted disks in place of ERNIE$DUA1:, reboot Ernie standalone mode. Copy ERNIE$DUA0 to the new ERNIE$DUA1 (will take about 2 hours), disconnect ERNIE$DUA0, hookup the old ERNIE$DUA1 and reboot. Shutdown ICY. Pull all the boards out of Icy and Bib (Bib has been shutdown since yesterday) and trade cabinets. Hookup the drive removed from Ernie (needs no reformatting) and the other drive from Kim to Icy. Hookup the little drive that was on Icy to Bib. Adjust software letting Icy and Bib know that they now have disks and reboot them. As you might well imagine, this is going to take SOME time to complete and due to vacation conflicts, I'd like to get going on it immediately. I propose the following schedule, and if unless there are some serious objections, this it roughly what'll happen: Beginning tonight (6/10/88) 19:00 - shutdown Gawd and dismount Kim$userdisk. The copy from Kim to gawd will run overnight. Tomorrow (6/11/88) 10:00-12:00 Kim will be down to disconnect drives. Icy will be shutdown from about noon saturday until monday. When or if the Zippy DRC batch job currently running on Ernie completes on sunday, I'll begin the Ernie disk to disk copy. If not, then I'll do it next week. In summary: This eve, Kim and Gawd will be down until about noon tomorrow. Icy will be down tomorrow through monday. Bib will be down until monday. Ernie will probably be down all day sunday. ds
