Thanks to all who replied - too many to list.
Special thanks to Kenn Owen who took the time to swap a drive on his system,
and to Venkat D who was kind enough to call me up.
----Creator series Ultra 1 running Solaris 2.5.1.
Original problem: How to move a disk ( call it disk A ) with a working OS from the bottom slot to the top slot.
Reason: Wanted to add a second drive ( call it B ). Ended up with a 1.5 in form factor drive, which would only fit in the bottom slot.
Details; After changing c0t0* to c0t1* in vfstab, and moving the drive, booting disk1 always bombed with a message about not being able to mount /dev/dsk/c0t1d0s0 or /usr.
same with boot disk1 -r same when booting after touching /reconfigure
conclusion: I was missing the driver device files under /devices. It appears that without them, you can not do a reconfiguration boot. Makes no sense to me, perhaps someone could enlighten me.
fix: 1: install a rudimentary system on the new drive - diskB, in the bottom slot. 2: do a reconfiguration boot from disk B. In this case: boot disk2 -r
3: reconfigure the /dev & /device files on disk A a: mount the root partition of disk A under /mnt on disk B's fs b: run /usr/sbin/drvconfig -r /mnt/device ( see note 1 below ) /usr/sbin/devlink -r /mnt /usr/sbin/disks -r /mnt /usr/sbin/ucblinks -r /mnt This script is based on one found in one of the FAQ's - comp.sys.sun.faq I think. The idea is to rebuild the device files, and put them on disk A, not on disk B where they would go by default.
4: do a reconfiguration reboot from disk A
5: set the default boot device to disk1
Notes:
1: drvconfig insists on writing to /etc/path_to_inst. I could find no way to alter this behavior, so trying pull this scheme off while booted from the CD would not work. Drvconfig couldn't write to /etc so it failed to write the /device files as well. That's why we ended up installing the mimimum system on drive B - so drvconfig would have a /etc/path_to_inst that it could write to.
2: I did an installboot to drive A somewhere in the process, but I don't think that effected anything. ( It was already bootable )
3: The docs say that the bottom slot is always target 0, the top slot is always target 1. It seems to work that way for the top slot - that drive is seen as target 1 even when jumpered to be target 0. However, right now, the drive in the bottom is jumpered to be target 2, and that is how probe-scsi and the OS sees it.
Finally:
I'm really confused by all this. I can't imagine that it's this hard to just move a disk drive. I'm still open to anyone's thoughts on this, and will post a better answer to the list if I get one.
