Diagnose Controller

This command runs diagnostic tests on the controller. The diagnostic tests consist of loopback tests in
which data is written to the disk drives and read from the disk drives.
Syntax
diagnose controller [(a | b)]
loopbackDriveChannel=(allchannels | (1 | 2 | 3 | 4 | 5 | 6 | 7 | 8))
testID=(1 | 2 | 3 | discreteLines)
[patternFile="filename"]
Parameters
Parameter

Description
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.
The disk drive channels on which you want to run
the diagnostic tests. You can either choose to run
the diagnostics on all channels or select a specific
channel on which to run diagnostics. If you select a
specific channel, valid values for the disk drive
channels are 1, 2, 3, or 4.
The identifier for the diagnostic test you want to
run. The identifier and corresponding tests are as
follows:
v 1 – Read test
v 2 – Write test
v 3 – Data loop-back test
v discreteLines – Discrete lines diagnostic test
The name of a file that contains a data pattern that
you want to use as test data. Enclose the file name
of the data pattern in double quotation marks (" ").
Header
The alphanumeric identifier (including - and _) of the
Performance Read Cache that you want to delete.

enclose the identifier in double quotation marks (" ")
inside square brackets.
