4c Cannot find a boot disk. BMC and MP are
running.
Nothing may be logged for this condition.
1. Reinsert the boot disk into the drive bay
(refer to “Supported Configurations” on
page 84 for more details).
2. Search for the boot disk’s ACPI path using
the EFI shell (map –r) command (refer to “I/O
Subsystem (SCSI, LAN, FibreChannel, HDD,
and Core I/O)” on page 90 for more details).
3. Examine the MP logs for entries related to
processors, processor power modules (PPM)s,
and shared memory, and core I/O devices
(refer to “Errors and Error Logs” on page 81
for more details).
4. As a last resort, replace the server blade.
Preceding problem is fixed when all boot
paths are found.
5 Cannot see OS prompt on system console.

and shared memory, and core I/O devices
(refer to “Errors and Error Logs” on page 81
for more details).

6 Cannot read System Event
Log from the system
console...
System event logging has stopped and a BMC malfunction is
assumed (health is steady green and power is steady green).
1. Examine console messages for any EFI errors or warnings
about BMC operation or communications.
2. Test the operation of the BMC by toggling the UID locator
LED on the front panel -- the blue LED is turned On/Off by
the BMC through the system console.
Preceding problem is fixed when the System Event Log
resumes logging.
