2. Possible Cause: In HCM, the boot option is set to Auto Discovered from Fabric or First Visible
LUN in the Boot over SAN dialog box.
Action: Change the boot options to User Configured LUNs in the Boot Over SAN dialog box.
Refer to the Boot Code chapter in the
Brocade Adapters Installation and Reference Manual for
details.
Remote LUNs are not visible to the host
If LUNs from which the host system will boot are not visible from the host system, refer to the
following descriptions of possible causes and recommended actions to help resolve the problem.
1. Possible Cause: The driver update disk (DUD) used to install the driver and necessary file
structure on remote LUNs for boot over SAN operation is not correct for the host operating
system being installed on the LUN.
Action: Download and install the correct the driver update disk for the OS that is being
installed. Download the DUD from the Brocade adapter website (
www.brocade.com/hba or
www.brocade.com/cna) .
2. Possible Cause: Missing or improper storage array LUN mask setting.
Action: Check LUN mapping and masking using the storage array configuration applications.
3. Possible Cause: Missing or improper storage array LUN mask setting.
Action: Check LUN mapping and masking using storage array configuration tools.
4. Possible Cause: Adapter driver not loaded.
Action: The adapter driver may not be loaded. Refer to “Adapter driver installation verification”
on page 39 for methods to verify driver installation.
Cannot boot over SAN from installed CNAs
You cannot boot over SAN from CNAs, but can boot from HBAs installed on the same system.
Possible Cause: A maximum of four boot LUNs are exported to the system. Boot LUNs connected
through HBAs take precedence over boot LUNs connected through CNAs. If all four boot LUNs are
connected through HBAs, boot over SAN will not occur through installed CNAs.
Action: If you want to boot over SAN through a CNA, 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.
02a2: BMC System Error Log (SEL) Full`
/Press F1 to Continue, Press F2 to Setup/
Possible Cause: The System Event Log may become full of erroneous IPMI (intelligent platform
management interface) events reported by the system BIOS.
