Thanks.. I've proceeded further along but have finally hit a snag.



I was unable to install boot blocks using this:
Code:
# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/cwtxdys0 (uname = SUNW,Sun-Blade-2500)


I get syntax error: '(` unexpected


So, I skipped the step because my notes said I may have to install boot blocks, not definitely have to. I'm reusing an old drive and thought its probably already there.


But at this point, when I try to boot to the root volume in single user mode # boot -sw I get
Code:
Boot device: /pci@1d, 700000/scsi@4/disk@0,0  File and args: sw
The file just loaded dos not appear to be executable


Is this a boot block issue?

--- Post updated at 09:39 AM ---

I'm suspicious of uname and the device. (and the number for that matter)


Should it be something more like:
Code:
installboot /usr/platform/`SUNW,Sun-Blade-2500 -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s3

or:
Code:
installboot /usr/platform/`SUNW -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s3

0 is my root slice and 3 is my usr so I'm not sure which would be right

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 | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ od(1), uname(1), boot(1M), init(1M), kadb(1M), kernel(1M), monitor(1M), reboot(1M), rpc.bootparamd(1M), init.d(4), attributes(5) 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. 11 Apr 2005 installboot(1M)
