Using Dell Online Diagnostics 25

•

pediags <DEVICECLASS> --run time= x

(where

is the

number of minutes you want the test to run.)

This command allows you to run a diagnostic test for a specified duration.

For example,

pediags scsidevdiag --run device-index=1

test-index=1 time=30

runs the diagnostic test whose index is 1 on

the SCSI device whose device-index is 1 for 30 minutes. Tests stop

executing after they complete 72 hours or 999 passes, whichever occurs first.

NOTE: Runtime of the passes parameter is limited to 3 days (72 hours).

The minimum number of iterations supported is 1 and the maximum is 999.

NOTE: Always specify the time parameter in minutes and enter the time

parameter after the --run parameter.

NOTE: Running the pediags command on the device class from two different

consoles simultaneously may display the message: System

resources may have already been used by another

diagnostics instance

Aborting Online Diagnostics in CLI Mode Using <Ctrl><C>

Using <Ctrl><C> to abort with the --show command does not cause the

action to abort. When running tests, you may use <Ctrl><C> at any point

of time during the execution sequence to stop the test. No output may be

available and the test may exit with a blank message. This may occur if the

execution of the pediags command has been interrupted even before the

diagnostic test has started. If you abort a test that has already started, the test

may abort with a Test was aborted by the user result event if the

Abort feature is supported by the particular test. For multiple passes, even if

the test supports Abort, the test may not abort with the Test was aborted

by the user result event. This might occur because the multiple pass test

may have been aborted during the transition from one pass to another.

Tests that do not support the Abort feature will always run to completion.

Scripting With the CLI

The Online Diagnostics CLI allows administrators to write batch programs or

scripts to be executed by the operating system. For an enterprise with many

systems, an administrator could write a script that runs diagnostic tests on

system components to determine their health.
