SUMMARY: Changing scsi host ID Sun Storedge PCI Dual Ultra3

Thanks to Drew Skinner with the quick and correct response, rather then 
paraphrase I've included his message for the archives:

** Begin Instructions **

Hi Tyler;

Here's the quick and dirty.

On one of the two hosts do the following:

1) Get to an OK prompt. Then run a reset-all followed by a 
probe-scsi-all to get your device id's
2) Edit your nvramrc (those docs are on docs.sun.com - just search for 
nvramrc
3) Run an nvstore. setenv use-nvramrc? to true.
4) Reconfigure reboot

Sample from one of my systems and it's nvram settings:

nvramrc=devalias altboot /pci@8,600000/SUNW,qlc@2/fp@0,0/disk@3,0
devalias bootdisk /pci@8,600000/SUNW,qlc@2/fp@0,0/disk@0,0
probe-all install-console banner
cd /pci@9,700000/scsi@4
6 " scsi-initiator-id" integer-property
device-end
cd /pci@8,700000/scsi@5
6 " scsi-initiator-id" integer-property
device-end
banner

The first two lines are the boot disks. The real stuff for this begins 
with the probe-all
and ends with the banner statement. Control C will get you out of 
nvedit.

All the best,


Drew.
