Summary: Is this disk dead?

Short answer: No!  I just wasn't waiting long enough for format to through
SCSI errors.

I ran format again and it spit out the original error 20 times, then a wrong
magic number error:

scsi: [ID 107833 kern.warning] WARNING: /pci@1f,4000/scsi@3/sd@9,0 (sd8):
 Corrupt label; wrong magic number

and then happily proceeded to format the disk...

Verifying media...
        pass 0 - pattern = 0xc6dec6de
        pass 1 - pattern = 0x6db6db6d
Total of 0 defective blocks repaired.

Thanks to Bob Payne, Tobias Kronwitter and Darren Dunham for their replies.

Tobias suggested:
dd if=/dev/zero of=/dev/rdsk/c0t9d0s2
Which did work, once but I could not repeat it again.

My appreciation to the list and big shout out to everyone who is away from
their office!
