Solaris10 vx one disk failed and second is removed

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)

        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:

https://docs.oracle.com/cd/E19396-01/817-6546/cfhefabj/index.html

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:

Rebooting with command: boot -s
