HBA problems

3. Possible Cause: The link between the adapter port and target is not active yet.
Action: Check that the speeds for the adapter port and the connected switch port match. The
best approach is to set both speeds to “auto” or “autonegotiate.”
Unable to boot from the stored boot device settings in the adapter
The host is unable to boot from the boot device settings stored in the adapter. A “No boot LUNs
configured” message will display next to the adapter value when booting.
1. Possible Cause: In the Brocade BIOS Configuration Utility, the Boot LUN field In the Adapter
Settings screen is set to Auto Discover or First LUN.
Action: Change the Boot LUN setting on the Adapters Settings screen to Flash Values. Refer to
“Configuring boot over SAN” on page 74 for details.
2. 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 “Configuring boot over SAN” on page 74 for details.
Remote LUNs are not visible to the host
Remote LUNs configured for boot over SAN feature are not available from the host.
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 HBA website (www.brocade.com/hba).
Possible Cause: Missing or improper storage array LUN mask setting.
Action: Check LUN mapping and masking using the storage array configuration applications.
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.
Action: Perform the following steps:
1. Boot the server and press F10 when prompted to run BIOS Setup.
2. Select the Advanced menu.
3. Scroll down to IPMI and press ENTER.
4. Scroll down to the System Event Log selection and press ENTER.
5. At the Clear System Event Log selection, press ENTER to toggle between Enable and Disable.
6. Select Enable.
