No. What is usually done is you leave ID 7 unused. I know of AIX boxes=20
that did this like a decade ago. As long as they don't boot at the same=20
time, you're fine. And since you can control powerup, you're ok.

Note that FC and iSCSI don't need tweaked IDs. SPI (Parallel SCSI) needs=20
them. I'm not sure about Firewire.

Take care,

Bill
