All Cracked it! First of all, many thanks (in no particular order) to Steven Haywood, Pascal Grostabussiat, Jeffrey Wimmer, Trent Petrasek, Rainer Heilke, Bertrand Hutin and Bryan Crawford. They all provided some great suggestions, but as it turned out, Rainier led me towards the answer when he said: Rainer: "The one "problem" with this rearrangement is that you have to make sure your OBP knows what partition to boot from." Now, I'd spent all morning (basically, ahem...) trying different versions on the "ls -l c1t0d0s3" output which I thought was quite logical. lrwxrwxrwx 1 root root 48 Mar 3 16:32 c1t0d0s3 -> ../../devices/pci@1f,0/pci@1/scsi@8/sd@0,0:d,raw So, boot /pci@1f,0/pci@1/scsi@8/sd@0,0:d,raw boot /pci@1f,0/pci@1/scsi@8/sd@0,0:d boot /pci@1f,0/pci@1/scsi@8/sd@0,3:d Etc.. The winner in the end was to do a 'show-disks' in OBP. This told me that - amongst others - the disk I was interested in was /pci@1f,0/pci@1/scsi@8/disk Of course, 'disk' shows up in devalias already. But naturally that's slice 0. Therefore: boot /pci@1f,0/pci@1/scsi@8/disk:d ":d" means "slice 3". This I did, and everything comes up roses. I set boot-device to be "disk:d mirror_root net" It's *so* obvious now I've done it, but I spent so long pursuing the /sd@etcetc route that I never thought of trying this syntax. Doubtless there's a similar @sd one, but I'm not inclined to look for it at the moment ! Many thanks again to all. Now I can get back on mirroring the disk. Lastly, the main points to remember if you find yourself in this situation - apart from the above - are: Check your vfstab! Check it again! Perhaps try to reinstall a boot block on the slice you are trying to boot Swap on slice 0 is not a bad idea, but make it start at cylinder 1 in case it erases the partition table Andrew _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Thu Mar 6 12:03:26 2003
