C.1.1 Message Types
A syslog daemon exists in the hardware RAID controller that records system
messages and provides for remote monitoring. There are four possible levels of
messages, listed in
TABLE C-1
in order of severity.
C.1.2 FRU Identifiers
The syntax of the error message uses a FRU identifier to refer to a particular FRU in
a disk tray. This identifier contains a unit constant (u), the unit number (n), the FRU
constant (ctr for controller card, pcu for power and cooling unit, 1 for interconnect
card, d for disk drive), and the FRU number (n).
TABLE C-1
Message Types
Message Type Definition
Error Indicates a critical system event requiring immediate user
intervention or attention. For example, an over temperature
condition or a detected FRU being removed.
Warning Indicates a possible event requiring eventual user intervention. For
example, a FRU being disabled and recovery procedure executed.
Notice Indicates a system event that might be a side effect of other events
or may be a normal condition. For example, the power switch is
turned off.
Information Indicates a system event that has no consequence on the running
health of the system. For example, a good state of a FRU.
