I haver recently been called on to try to resuscitate an IRIS 2400Turbo that has (once again) munched its disks. I used to be primary care provider for this machine when it was a lowly IRIS 2400. While I was caring for it I made several (3) bootable tapes, and used them several times to rebuild the machine from scratch. The sequence went something like: tb mdfex ( to boot the md formatter/exerciser) Z ( enter a security password) xxxxx ( stupid password :)) t ( tape to disk copy) 2 ( second file on tape) 0 ( md 0) g ( partition g, the boot area) go ( do it) t ( tape to disk copy) 3 ( third file on tape) 0 ( md 0) a ( partition a, the root partition) go ( do it) When I tried to go through this sequence on the now upgraded machine, I found that it seems to have a new monitor. The command that loads mdfex from the bootable tape seems to be: b ct.0:mdfex The password stuff still works. When I went to use the "t20ggo" sequence it reported copying 0 blocks to md0g. This worried me, but I continued on. The "t20ago" sequence reported copying some larger number of blocks, and actually printed a sequence of "5 10 15 ... 40" as it worked. Now when I tried to boot the machine, using the good old "b<cr>" it informed me that it couldn't find "defaultboot". It seems that the "t20ggo" not only didn't copy anything, but actually zapped what used to be there. The OS that we have been running is apparently GL2/W3.5. There are roms on the cpu board labelled IP2/3.0.7, and most of the labelled chips have some label on them which reads IP2something. So, I have two questions. 1. Are my old (3.5 from an IRIS 2400) bootable tapes any good? If so, can someone tell me what has changed about the rebuilding procedure. 2. If I need a new bootable tape, can someone out there help me? (oh yeah, did I mention that the machine *isn't* under maintenance...). It seems that there shouldn't be a licensing problem, since we own the machine and the system, our problem is just that the dealer who we bought it from didn't bother to give us the tools that we need to solve such problems, and the people who were maintaining the machine weren't informed of the need for a set of bootable tapes. If you reply to this via e-mail, please also send a copy to marvil@boulder.colorado.edu, since she is the most heavily impacted user, and would like to keep up with what is happening. I will be out of town until Thurs, 10-12-89, but someone will be watching this newsgroup for me. THANKS. g.
