The self-test messages displayed by the operating system consist of:
1. Self-Test Waming and Error Messages.
2. Fatal Error Messages.
3. Software Failure Messages

t set. -
This message indicates that either the contents of the NVM are not
valid at powerup or the clock has not been set since this condition was detected. Possible causes: a
bad battery on the SCM board, or computer powered down for more than 2 weeks. The condition
does not stop the system operation.
Self test error 1: liD address AA, SS STATUS: XXXXXXXX
Where:
AA = Select code
SS
=
Subaddress
XXXXXXXX
=
Device or card dependent error information (in hexadecimal).
This error message is displayed as a result of the self-test failure of an I/O device. The select code
subaddress denote the device, and the device dependent error information indicates the nature of
the failure. System operation can continue provided that use of the failed device is not required.
Self test error 2: CHECKSUM for Se9fTiertt NN -
When the system is powered up, or a system
reset is executed, the checksum for every code segment of the operating system is computed and
compared to a checksum in the operating system code. When the checksums do not agree for a
segment, the segment number is stored. As a result, the segment reported is the last segment for
which a checksum error was detected. The operation of the system is not halted, however, further
operation is at your own risk.
Self test error 3:
XXXX
NN
Where:
XXXX
=
"CPU#", "IOP#", or "MC#_".
NN
=
The Nth of that type of component (counting from the bottom of the stack).
This error occurs when the system is able to get completely through the board self-test and the
loader self-test, but a failed stack component is detected by the operating system. The message
indicates the type of component which has failed and its relative position in the stack. Operation of
the system can continue,
if
the failed board is not required.
Self test error 4: MeMOry reduced to: NNNNNNNN Bytes. MCs:<llst>
Where:
NNNNNNNN
=
number of bytes (in decimal) that are available.
<list>
=
A list of Memory Controller numbers which had failures. Up to 10 MC
numbers are printed in 10 two character fields, with no intervening spaces. For
example: "MCs: 1 210" indicates that Memory Controllers 1, 2, and 10 have failed
the memory test. Memory boards (and memory controllers) are numbered from 1,
starting at the bottom of the RAM.
This number represents all usable RAM in the system including memory used to hold code seg-
ments.
