Can you please check if the below steps are correct and if changes are need to be made further?

-Full OS backup is to be taken prior to activity
-Make a backup copy of /etc/vfstab file, comment out ossdg entries
-Identify the rootmirror disk using format
-set system eeprom to auto-boot false,
#eeprom auto-boot?=false
then
init 0 to bring system to ok> prompt
pull out the SE3510 FC connection cables

- Pull out rootmirror 36G HDD and insert 72G HDD
-Boot up the system using the rootdisk
- format new drive and label disk with appropriate partition sizing
(need confirmation from Ericson)

-newfs on the filesystems on the new 72G HDD
Newfs /dev/rdsk/c2t0d0s0
- mount root slice from the new HDD to a temp mount point
Mkdir /s0
Mount /dev/rdsk/c2t0d0s0 /s0
- perform ufsdump / ufsrestore for root partition
Ufsdump 0f - / | (cd /s0; ufsrestore rf -)
-when root partition is done with restoration, perform installboot bootblk on new disk

Cd /usr/platform/`uname -i`/lib/fs/ufs
Installboot bootblk /dev/rdsk/c2t0d0s0
Backup /etc/system file and /etc/vfstab
Touch /s0/etc/vx/reconfig.d/state.d/install-db
Vi /s0/etc/system :-(remove all rootdev statements)
Cp /s0/etc/vfstab.prevm /s0/etc/vfstab
- umount and remove the temp dirs created at step6
Umount /s0

- bring the system down to ok> prompt -> poweroff
-swap in new HDD to primary controller
-plug in FC cables
- boot the system to single user, check vfstab entries and clear filesystem errors (if any), format and check the cxtxdx
-replace the backup vfstab file with ossdg entries

- boot the system to multi-user
#vxiod set 10
#vxconfigd -m disable -k
#/usr/lib/vxvm/bin/vxencap rootdisk=c0t0d0
#init 0
Ok> boot
Verify using vxdisk list, vxdg list if the status is ok.
- slot in 2nd new HDD to secondary controller, make sure OS detects the disk, label the disk.
Devfsadm -C
#vxdctl enable
-use vxdiskadm -> choose option 4 (ensure VM detects as rootmirror not found) choose option 5 (to sync the rootmirror disk)
-vxtask list (monitor disk synchronization to complete)

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

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

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.
