The testID parameter takes the following options, which you can use to verify that a RAID controller module is functioning correctly:

1 — Reads the test

2 — Performs a data loop-back test

3 — Writes the test

The diagnostic tests consist of loop-back tests in which data is written to physical disks and read from the physical disks.

Parameters

Parameter

Description

 

 

controller

RAID controller module on which to run the

 

diagnostic tests. Valid RAID controller module

 

identifier values are 0 and 1. The identifier value is

 

0 for the RAID controller module on the top and 1

 

for the RAID controller module on the bottom

 

when viewed from the rear of the enclosure. You

 

must put brackets ([ ]) around the RAID controller

 

module identifier. If you do not specify a RAID

 

controller module, the storage management

 

software returns a syntax error.

loopbackPhysicalDiskChannel

Physical disk channel on which to run the

 

diagnostic tests. You can choose to run the

 

diagnostics on all channels or select a specific

 

channel on which to run diagnostics. Valid physical

 

disk channel values are 1 or 2.

 

NOTE: When you run a data loopback test,

 

you can optionally specify a file that contains

 

a data pattern. If you do not specify a file, the

 

firmware provides a default pattern.

testID

Identifier for the diagnostic test to run. The

 

identifier and corresponding tests are:

 

• 1 — Reads the test

 

• 2 — Write test

 

• 3 — Data loop-back test
