Boot errors and handling
The following sections describe boot errors and actions you can take to resolve
these errors.
Boot list
The following table describes boot list errors.
Table 4. Boot list errors
Message: “It was not possible to boot from any device specified in the VPD”
Reason The firmware found a valid VPD but it could not find bootable code on any
of the devices listed in it.
Action Specify at least one device in the BladeCenter Management Module that
contains bootable code. You need to access the Management Module
through its web interface and direct your browser to Blade Tasks
→
Configuration
→
Boot Sequence .
Message: “Boot list successfully read from VPD but no useful information received”
Reason The firmware found a valid VPD, but there are no devices listed in it. The
VPD has never been initialized.
Action Specify at least one device in the BladeCenter Management Module that
contains bootable code. You need to access the Management Module via
its web interface and direct your browser to Blade Tasks → Configuration
→
Boot Sequence .
Message: “Boot list could not be read from VPD”
Reason The firmware can not access the VPD. It is possible that a service
processor communication failure occurred.
Action Remove the Blade server, reinsert and restart it. If the problem persists,
replace the system board assembly.
Disk boot (yaboot)
The following table describes disk boot (yaboot) errors.
Table 5. Disk boot (yaboot) errors
Message: “Unable to open file, Invalid device”
Reason The boot loader was invoked with the wrong parameters. It could not find a
file that contained bootable code at the location specified.
Action Check that the parameters that you pass to yaboot describe the correct
device name, partition number and file system path. For more information,
refer to the yaboot documentation distributed with the yaboot source
(HOWTO-Booting with yaboot on PowerPC).
Message: “Couldn’t determine boot device”
Reason The boot loader was invoked without specifying the location of boot code.
Action Ensure that correct parameters are passed to yaboot, by either using the
firmware environment variables or passing them in the yaboot config file
yaboot.conf .
