Solaris 2.6 restore from tape
Hope someone can help me here...
I've got to restore an E450 with 300MHz cpus which was running Solaris 2.6 from tape. Regrettably the boot drive has failed.
I've access to the first release of Solaris 2.6 CD's and to a set of Solaris 9 CD's.
I remember that different E450 CPUs needed different releases of the 2.6 media set in order to boot correctly.
The tape was written using ufsdump.
So, to my questions?
Will this E450 boot from the Solaris 2.6 CD?
If not, will booting from the Solaris 9 CD be able to ufsrestore and then installboot correctly?
According to the notes I have of the restore process, while booted from the CD I'd issue this command to install the boot block:
installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0
but if I'm booted from a Solaris 9 CD would that result in a valid boot block for Solaris 2.6?
Many thanks for any and all assistance.

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
