Seems there's more going on than I realized. When I reboot reconfigure,
the host sees the other path to the devices, however, the host hangs when
trying to load the 'sys' module into the kernel. I have Sun and EMC
looking into the dump now. Thanks for your replies.

Re: reboot loses EMC disks(Document

I have a second path over another HBA (same card type, uses the same
driver) and those come up fine. That's what has me stumped. They have
sd.conf persistent bindings like so:
name="sd" class="scsi" target=4 lun=0 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=68 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=69 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=70 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=71 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=72 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=73 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=74 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=75 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=167 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=4 lun=168 hba="fcaw0" wwn="50060482cafdd4b3";
name="sd" class="scsi" target=5 lun=0 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=68 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=69 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=70 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=71 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=72 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=73 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=74 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=75 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=167 hba="fcaw1" wwn="50060482cafdd4bc";
name="sd" class="scsi" target=5 lun=168 hba="fcaw1" wwn="50060482cafdd4bc";
fcaw0's come online just fine. But not the fcaw1 luns. If I do
drvconfig,disks,devlinks /var/adm/messages finally says 'Target 5, Lun xx'
available. Then I run my vxdctl enable to get dmp happy.
I'm stumped as to why one would come up okay and the other needs further
encouragement.

Do you see other disks before or after the FA line? Any chance that the
fcaw driver is loading after the disks are seen?
Perhaps adding a forceload drv/fcaw to the /etc/system could help?
That's just a SWAG.
