Hello, gurus, First of all, many thanks to all those who replied. Particularly: Mike Salehi Dominic Clarke William Enestvedt It was a rather tense moment for me, so I appreciated even more the community's support. In fact, the problem was neither with the Ultra10, neither with any configuration quirks. All of my seven disks just happened to be physically dead (*Yes. It's true*). Which is the reason why I couldn't see them. We reconstructed everything from a remote backup, and now it's rolling along fine, except some cold sweat. What happened was rather incredible. The battery on which the A1000 was plugged on broke during the night, causing it to turn the A1000 on and off every 5 secs. Which treatment apparently ended up crashing all of my disks. All seven of them. What's fun about it is that on the same battery I had two SunFire V100's, and they suffered no damage. The two internal disks of the Ultra10 neither. Apparently, that could be because on the SunFire and the Ultra10 don't start the disks right away, since there is some latency in the boot process before starting the disks. The A1000, on the other hand, just does what he is told, that is: start the disks, shut them down, start them on again, etc... So, it's possible to totally screw up a disk bay made for maximum redundancy and data safety, under certain particular conditions, i.e. bad electrical supply in my case. I believe I'm the only one who's had this kind of experience. It's one of the very rare bad surprises I've had with Sun material. Any feedback is welcome. Rami Aubourg Original post below. *********************************************************** Hello, gurus, I had an Ultra10 connected to an A1000 with three mirrored disks. We had a serous power failure problem last night, and today I can't connect to the A100 anymore. A probe-scsi-all sees the seven channels attached to the three mirrored disks, plus the hot spare, and that's all. lad says there are no RAID devices. rm6 saw no disks. The internal disk leds light up, but not the ones on the A1000 corresponding to the disks We changed the scsi card , the SCSI cable, the controlles on the A1000, tried putting the disks on an entirely new A1000. Same effect. The last thing I can imagine is the terminator, or a deeper problem with the motherboard. The internal system disks on the Ultra10 are all right. My collleague's with the people who sold us the bay and the Ultra10 right now with the material, trying to fix the problem with them. I'm setting up another server with yesterday's backup if everything else fails. I'm also searching for some clues as to how we could access the disks on the A1000. Has anyone had this kind of problems with an A1000 before? Were there other tools that you used to acces the disks? And in case the disks are all right, is there a way to revert to a normal filesystem and plug them on another server, without using the A1000? Thanks in advance, Rami Aubourg ***************************************************** -- Lost Knowledge Sets Back Civilization _____________________________________________________________________ Envie de discuter en "live" avec vos amis ?
