Cannot boot over SAN from installed CNAs or Fabric Adapters
You cannot boot over SAN from CNAs or Fabric Adapter ports configured in CNA mode. However,
you can boot from HBAs or Fabric Adapter ports configured in HBA mode installed on the same
system.
Possible Cause: A maximum of four boot LUNs are exported to the system. Boot LUNs connected
through HBAs and Fabric Adapter ports configured in HBA mode take precedence over boot LUNs
connected through CNAs or Fabric Adapter ports configured in CNA mode. If all four boot LUNs are
connected through HBAs or Fabric Adapter HBA ports, boot over SAN will not occur through
installed CNAs or Fabric Adapter CNA ports.
Action: If you want to boot over SAN through a CNA or Fabric Adapter port configured in CNA mode,
disable BIOS on all installed HBAs. To disable BIOS, use BCU commands, the BIOS configuration
utility, or HCM. Refer to the "Boot Code" chapter in the Brocade Adapters Installation and
Reference Manual for instructions.
Boot from SAN may stop on some Hewlett Packard hosts
The boot process may stop on some Hewlett Packard systems, such as the HP DL180, and the
following message displays.
