Bug 15809064
Conditions:
System Platform: Oracle SPARC systems
Environment: HBA connected directly to supported storage
Boot Method: SAN boot via the HBA
Issue:
When the HBA is in an Oracle SPARC Enterprise T4-1 or T4-2 system, and a direct connection is made with a fiber-optic cable from the HBA to a storage device, the system might not detect any bootable volume on that storage device. When you attempt to boot using the storage device, an error message is displayed.
ERROR: boot-read fail
Workaround:
Do not boot from a bootable volume on a storage device if that storage device is directly connected to the HBA. Instead, if you want to boot using the storage attached to the HBA, use a SAN topology that includes one or more FC switches connected in the path between the HBA and the target storage device.
You can use a direct connection to storage as long as the system is booting the Oracle Solaris operating system from a boot device that is not connected directly to the HBA.
