Extended Test Option Description
RAID6Parity This option tests the ability of the Zip APC to generate and
verify RAID 6 parity data. Data buffers are setup in
processor memory and parity is generated in processor
memory. Some data buffers are set up in redundant parallel
architecture (RPA) memory and parity is generated for the
data within the RPA memory. The parity that is generated
within processor memory is then compared with the parity
in the Zip APC.
Notes
You can run the diagnostic test on only one controller in the storage subsystem at any one time.
Start Controller Trace
Syntax
This command starts an operation that saves debug trace information to a compressed file. The debug
trace information can be used by an IBM Technical Support representative to help analyze how well a
storage subsystem is running.
start controller [(a | b | both)] trace
dataType=(current | flushed | currentFlushed | all)
[forceFlush=(TRUE | FALSE)]
Parameters
Parameter Description
controller
The controller for which you want to collect the trace debug
information. Valid controller identifiers are
a
or
b
, where
a
is
the controller in slot A, and
b
is the controller in slot B. You
can also simultaneously collect debug for both controllers by
entering both. Enclose the controller identifier in square
brackets ([ ]). If you do not specify a controller, the storage
management software returns a syntax error.
dataType The type of data that you want to collect:
v current – Retrieves the current DQ traces
v flushed – Retrieves all flushed DQ traces
v currentFlushed – Retrieves both the current DQ trace and
the flushed DQ trace
v all
– Retrieves the current DQ trace, flushed DQ trace,
and all platform DQ traces
Note: If
dataType=flushed
and
forceFlush=True
, an error
message is returned indicating that only active traces can be
flushed to the buffer on retrieval.
forceFlush The setting to move the DQ information in the current
buffer to the flushed buffer when the DQ trace information
defined by the
dataType parameter is retrieved. To enable
force flush, set this parameter to TRUE . To disable
force
flush , set this parameter to FALSE .
Note: If
dataType=flushed
and
forceFlush=True
, an error
message is returned indicating that only active traces can be
flushed to the buffer on retrieval.
