It all depends on how your server(s) see the USB device. If it accepts it as a disk, format it and create & mount a filesystem then write your ufsdump to a file in that filesystem. The tricky bit is on the restore.

In the past I tried to script our OS restores from tape using a diskette to store the scripts so it would slice the disk and call the restores in the right order for each fileystem we needed to get a boot with including the one that contained ou data backup software. The diskette is not a recognised device when booted single-user from the install media so i had to give up. This was years ago, but it might be the same with a USB device.

You could, however, try something like this:-

Boot CD and plain install to a temporary partition
Boot your temporary partition
Mount the USB
Use ufsrestore to recover your OS from the file on the USB device
Change the eeprom settings to boot from your restored partition
Boot

No guarantees, but it might work. It's all in the testing.

Do you do the DR to hardware you own and can test on? If not and you go to a company that provides a recovery centre, talk to them. They usually will have people who have done this sort of thing before. Discuss your options with them and they might even give you a procedure.

A possible solution is that the recovery site provide a basic working server and lead you through the ufsrestore and eeprom updates, adding device drivers that you might needs etc. but as they are in this speciality as a business, they have probably considered most options already or will get an answer for you.

I hope that this helps,
Robin

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
