Parameters
Parameter Description
controller
The controller on which you want to run the diagnostic
tests. Valid controller identifiers are
a
or
b
, where
a
is the
controller in slot A, and
b
is the controller in slot B. Enclose
the controller identifier in square brackets ([ ]). If you do not
specify a controller, the storage management software
returns a syntax error.
diagnostic
The level of diagnostic testing that you want to run on the
host interface card. You can run one of these levels of
testing:
basic
– This option validates the ability of the base
controller to address and access data.
extended
– This option enables you to run more
comprehensive diagnostic tests on the base controller card.
extendedTestID
This parameter selects the extended test option that you
want to run.
If you choose the
extended
parameter, you must also used
the
extended TestID
parameter and one of the extended test
options.
Extended Test Option Description
SRAM This option tests for address, data, and data retention. The
address test attempts to write to specific address offsets. The
data test attempts to write several data patterns to the
address offsets. The data retention test attempts to write a
data pattern and then read the data pattern back after a
delay. The purpose of the SRAM option is to find memory
parity or error correcting code (ECC) errors.
FIFO This option tests the active processor chip (APC) first in,
first out (FIFO) data transmission of the Zip chip. The APC
FIFO channels are tested concurrently by writing and
verifying different patterns to each channel.
dataCopy This option tests the ability of the Zip chip to support data
copy operations that can copy data from one area of the Zip
SDRAM to another area of the Zip SDRAM. This test is
performed on any available section of the Zip chip that is
not busy.
RAID5Parity This option tests the ability of the Zip APC to generate and
verify RAID 5 parity data. Data buffers are setup in
processor memory and parity is generated in process or
memory. Some data buffers are set up in 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.
