Hi folks I'm bringing up an old Multiprise 3000 - 7060-30. For fun and education rather than production needless to say!
All is mostly well so far but I'm having a problem configuring the internal DASD. There are 11 18GB disks in there and 7 SSA jumpers. The loop and plugging rules appear to be correct and that side of things seems fine; I've read the manuals there carefully! I've found I have one dud disk - if I run ISSACFG from the boot floppies it formats test and certifies just fine - but for some reason the internal disk subsytem configurator tool on the SE red-boxes it. I have one spare disk - which turns out to be completely dead. So I don't have enough working disks & jumpers to populate both groups of internal DASD with the required 16 valid devices. And if there's just one invalid or faulty device present the internal disk subsytem configurator tool refuses to create a logical storage subsystem. No problem I think; I don't have enough working bits for both groups so I'll only use the disks in group 0 - the leftmost two columns of DASD. I remove all the disks and jumpers from group 1 and the SSA adaptor from group 1 - and replug the SSA cables appropriately. I check it out with diskette boot ISSACFG; all is well; I have a functioning string of 8 good disks. Then I bring up the SE; I perform a POR; I start the internal disk subsytem configurator tool. It shows all 8 drives in group 0 working (blue squares) and all group 1 blank (white squares) - just as I expected. Unexpectedly it *still* won't create an LSS; the message about a faulty disk being present is gone but instead I get "The HDDs are not plugged in the order as required for this frame. The LSS configuration data could not be built or upgraded. Message ID: 0x8104" Any suggestions? I don't see how the plugging order *could* be any different; all slots in group 0 are plugged with working valid drives. No jumpers are used. Specific questions: 1. Is what I'm trying to do valid? i.e. run the machine with only 8 internal disks installed in group 0 - and have all the group 1 disks and SSA adapter removed and their spaces covered with blanking plates? The manual implies this should be possible. Or does *every* slot have to populated with a working disk or jumper and both SSA adapters installed - even if the SSA *loop* is only configured to use the group 0 adapter and disks? Refer to http://www-01.ibm.com/support/docview.wss?uid=isg202df2e6254dd7e3c852568b000761b0f&aid=1 - pages 7-2 to 7-7. I'm trying to implement figure 7-1 since I don't have enough working devices for figure 7-2 which was the original configuration. 2. Or am I doing it wrong? Should the order of actions be: Bring up the SE *then* use ISSACFG to create a RAID 5 array with hot spare using the 8 drives BEFORE performing a POR (turning control of the devices over to the PCI-STI bridge) THEN use the internal disk subsytem configurator tool to create an LSS from an already-created array? 3. Does anyone have any spare 7060 18GB SSA drives or jumpers lying in some dark closet?! I'm going to need some sooner or later anyway! 4. Does anyone have a spare 7060 DAT tape drive lying around? Both of mine appear to be flaky... and I'm going to need that sooner or later too! 5. If I abandon internal DASD completely for now and decide to use only emulated DASD on the SE array (which works perfectly) can I replace the 9GB SE array disks with 18GB units? I know I would have to reformat them to 512 byte blocks first and reinstall the SE from CDROM - but would it work? I could create a much bigger G: partition for a useful amount of emulated DASD that way. 6. I've heard tell of people who decided to throw away the SE array completely and instead boot the SE from an IDE disk connected to the IDE port on the SE SBC. Obviously that would require tweaking of the drivers etc. on the SE installation. Any comments or links to documentation on what exactly people did to make that work if the story is true?
