I agree with what the guys just said.


Easy steps:

1. boot from CDROM in single user mode.

2. edit /etc/vfstab and put the root disk as a raw device again, put the disk you want to boot from.


3. remove the /etc/system entry of the SVM (or better commented ). It's one line usually towards the of the file, starts like this

* Begin MD
* End MD


(make sure you know which disk you are mounting and editing, as you have two copies of the files, one in each disk).


then from the OK prompt, just boot from the second disk.

Assuming that you have made the mirror bootable (bootblk)
if you mirrored using SVM, then you don't need to install bootblk manually. When you backup or dump the root filesystem, then you need to install bootblk. But with SVM root mirrors, this step is not required.

installboot

installboot(1M) 														   installboot(1M)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk	       The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
		       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

	      example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
		   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

	   directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

	   second level program to boot from a disk or CD

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
