Hi --

Thanks to:

        Chuck, Thomas M. Payerle, Darren Dunham and others who provided
        excellent information on this topic.

It turns out that installboot is the proper method to use to reinstall a
corrupted boot sector even when disksuite is used.

Several people also pointed out that disksuite does not encapsulate the
disk(s) like Vertias Volume Manager does.

Also, thanks to Chuck for sending out an extremly helpful summary from
that list that was posted back on 24Jul2005 which explained how to access
metadevices when booting from CDROM.

Hi --

All of a sudden our E450 which has its disks mirrored with disk suite hung
up.  We had to power cycle the system and when the system attempts to boot
the following message is displayed:

        Boot load failed.
        The file just loaded does not appear to be executable.

This usually indicates a corrupted or missing boot block, but the same
also happens when we attempt to boot from the mirrored disk.  Could it
possibly be that disksuite copied the bad boot block to the mirrored disk

Since these disks have disksuite enabled on them, what is the appropriate
method for restoring the boot block?

I can boot using a cdrom but the disksuite drivers are not loaded and
the system won't know about /dev/md/???

Will I destroy disksuite metadata if I say :

        installboot /dev/rdsk/c0t0d0s0 ?

What is the best method to recover from this problem?

Thanks for any input one can provide.
