Disks got swapped - LDOM . -But how ?

Team,
I'm again end up in a trouble here.. here is what happened.
My boot device of LDOM was c0d0s0(36GB) and i had another disk (*c0d1s0 -10GB*) which has zfs and that is the boot disk of a zone .
After a power /network failure, i found that , the disks got changed..
Now c0d0s0 is 10GB and c0d1s0 is 36 GB..
Actually this resulted maintenace mode of LDOM and through failsafe i logged in and edited vfstab to reflect all the mount as c0d1s* and LDOM is okay.
But now the Zone is not booting up, and the reason is the Zpool is in unavailable state ( Since its disk(c0d1s0) is missing).
Now my questions are
1. How can i recover from this ?
Can i change the disks back to normal (from d0 to d1 and vice versa ) or how will edit the zpool to look for c0d0s0 instead of c0d1s0
2. How the disks got interchaged ? ( from d0 to d1 and vice versa )
Thanks in advance for the help..

Disk numbering may change when you remove and then re-add virtual disks, because, by default,
during the bind, vdisks are numbered starting from 0 in the order they have been added.
So I think it is possible that vdisks get switched when to do that:
- add one vdiskA -> c0d0
- add one vdiskB -> c0d1
- remove vdiskA (c0d0)
- re-add vdiskA (c0d0)
- unbind and re-bind the domain
- after the new bind, vdiskB will appear as c0d0 and vdiskA as c0d1
This is because vdiskB now appears before vdiskA (because vdiskA was removed and
re-added). So vdiskB is the first disk (c0d0) and vdiskA the second disk (c0d1).
With LDoms 1.2, you can prevent this by specifying the id of the vdisk, see the LDoms
admin guide:
http://docs.sun.com/app/docs/doc/820-7253/virtualdiskidanddevicename?l=en&a=view
Note that the id has some persistence issues tracked in bug 6847784 (vdisk/vnet/vsw id
property should be treat as a constraint) which should be fixed soon.
