Understanding Service Action Codes
and Modifiers
SACs are used to help define the cause of the problem. If a
failure occurs that requires operator intervention and/or a
service call, a SAC is generated and displayed on the operator
panel. A SAC is the result of the Scalar 10K firmware
analyzing all pertinent system information available at the
time of a failure, such as sense data, the operation in progress,
error and threshold data, and any data returned from
diagnostic routines invoked by the firmware to isolate the
failure.
When a SAC is displayed on the operator panel, make sure to
write down all of the SAC information displayed, including
the 10-character code (for example, 0x02110000) that follows
the SAC. This information can be used to help diagnose the
problem.
Each SAC consists of three bytes (
nn xx yy)
or four bytes
(
nn xx yy z)
as described below:
•
nn
: SAC.
•
xx yy z
: SAC modifier. For most SACs, the modifier has a
value of
00 00
but for some SACs, this value is used to
further identify the physical location of the failing FRU or
component as described for
xx
yy
. The additional
z
byte is
the single digit character error code displayed by tape
drives. The
z
byte provides tape drive information that
may or may not be useful in determining the problem.
•
xx
is the rack where the failing FRU or component is
located.
xx
has value ranging from
01
to
16
:
•
00
: do not care condition
•
01-16
: rack number from
1
to
16
•
yy
has a number of values depending on the SAC:
•
00
: do not care condition
