Hello All,
is it posible to save my data and start up from at least one good disk on a Solaris server in this case?:
[root@host1:/]$ vxdisk list DEVICE TYPE DISK GROUP STATUS c1t0d0s2 auto:sliced rootdg01 rootdg online failing c1t1d0s2 auto:sliced rootdg03 rootdg online - - rootdg02 rootdg removed was:c1t1d0s2 [root@host1:/]$
I somehow started up the server from ramdisk. I'm in readonly mode, but I can manually mount FS if needed.
The problem is that c1t0d0s2 failed:
WARNING: /pci@1c,600000/scsi@2 (glm0): Resetting scsi bus, got incorrect phase from (0,0) WARNING: /pci@1c,600000/scsi@2 (glm0): got SCSI bus reset WARNING: /pci@1c,600000/scsi@2 (glm0): Resetting scsi bus, got incorrect phase from (0,0) WARNING: /pci@1c,600000/scsi@2 (glm0): got SCSI bus reset WARNING: /pci@1c,600000/scsi@2/sd@0,0 (sd0): auto request sense failed (reason=reset)
and the second disk c1t1d0s2 is in a strange state which I don't understand - it's part of rootdg02 which is ok and also part of rootdg03 which is removed. I can't mount this disk c1t1d0s0,1,3,4,...
[root@host1:/]$ mount /dev/dsk/c1t1d0s1 /mnt mount: I/O error mount: Cannot mount /dev/dsk/c1t1d0s1 [root@host1:/]$
Thank you for your comments.

I tried to de-encapsulate disks and boot from second disk.
Procedure:

or
http://unix.ittoolbox.com/groups/technical-functional/solaris-l/recover-failed-encapsulated-veritas-root-disk-3793693
But system couldn't boot from this disk despite I was able to mount it, edit vfstab, ... and install boot:
installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t1d0s0
Can't boot:
