Memory parity error log fields
The following memory error log fields are pertinent
when a memory parity error occurs:
The
ERROR SYNDROME field identifies the
memory parity error.
The
MEM REG fields give the following memory
failure information:
HARD CNT shows how many errors recurred
on both read and write operations.
SOFT CNT shows how many errors recurred
on read but cleared on write.
TRAN CNT shows how many errors did not
recur on read.
DATA BIT IN ERROR or PARITY BIT
IN ERROR
indicates whether a data bit or a
parity bit failed.
HIGH BYTE IN ERROR or LOW BYTE IN
ERROR
identifies the byte where the error
occurred.
MEMORY PARITY ERROR lists the error
type (hard, soft, transient).
D0-15 or D16-31 tells whether the low
(left) or high (right) SIMM failed.
BANK tells which bank of memory failed.
The
PHYSICAL ADDRESS field identifies the
block being read at failure.
