Boot problem with Sparc Ultra 5 - Solaris 9

[rainman]

I'm trying to boot up a Sparc Ultra 5 w/Solaris 9 and I'm receiving the following error during OpenBoot:

Boot device: disk FIle and args:
The file just loaded does not appear to be executable.
ok [prompt]

I have been into PC's and networking for many years, however I am very new with Sun/Solaris. To me it seems as if the device is ready to boot but it can't find a boot record to read from? (MBR corrupted?)

Can someone explain to me what is going on and maybe point me in the right direction? If anybody needs any information I can gladly post it.

You will need to boot to the CDROM. When you get to the OK? prompt type "boot cdrom".

Hope this helps...

Either you boot block is corrupted / missing or you are pointing to the wrong drive to boot from. The former is only likely if you have had a disk corruption or done a filesystem relayout. If this is the case you need to reinstall the bootblock - boot from cd and call

installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0 <-(substitute your root disk here)

mount /dev/rdsk/c0t0d0s0 /mnt and check the directory /mnt/platform exists - if not you will need to restore the OS from backup

For the latter case - wron boot device..

The boot process looks at the boot-device and boot-file Prom settings to see where to boot from.

printenv from the ok prompt will show these values.
devalias will show the real devices that the aliases disk disk1 etc are set to.
probe-scsi shows the actual connected scsi devices you have.

To boot from another disk use boot <device>
