Hi all,

I'm having a problem getting a new 18GB external ultra-scsi disk recognized 
on a new Ultra 5. The drive is scsi ID 3 and it's connected to a PCI ultra-scsi 
adapter card.

After attaching the drive and doing "stop a" to interrupt the boot process,  
typing "probe-scsi-all" at the OK prompt, I get

/pci@1f,0/pci@1/scsi@1,1

Script interrupt, no message after disconnect
Warning: attempt to map-out on dma-alloc range: e000 c0ef2000


From reading the docs I should be getting a target number after the host
adapter card device line.

Going further with the "boot -r" command it doesn't seem to 
properly recognize the target scsi device. There are additional warning 
messages:

Warning /pci@1f....
Control command timeout for target 3.0
.
.
.
Warning target 3 reducing sync transfer rate

and then finally something to the effect of target 3 reverting to asynchronous 
mode.

AFter the system is up and issuing the "format" command, only the internal IDE 
drive is recognized.

Any ideas?

Thanks.

Carl
