36 omdiag: Using the Diagnostic Service
omdiag storage raidctrl
Use the omdiag storage raidctrl command to validate normal operations of Adaptec and LSI RAID
controllers and connected hard drives. This command allows a user to test all RAID controllers and attached
drives. With more command options, a specific controller and its connected hard drives may be tested.
• Adaptec RAID Controller Hardware Test — Performs various tests to validate normal operations of
Adaptec RAID controllers. It allows a user to selectively test a specific controller. The test retrieves and
verifies the status information of the main components of the controller. It performs basic and
advanced operations to verify the working status of the controller. The Adaptec Controller Hardware
test performs the following tests:
– Pause-resume I/O Test — Verifies the Pause I/O and Resume I/O functions of the controller on all
of the buses.
– Device scan Test — Verifies the status of devices attached to the controller. This test takes a
snapshot of the status of current attached devices, rescans for all devices, and then compares the
status with the first snapshot, reporting any changes.
– NVRAM and battery test Test — Checks for the existence of a nonvolatile random access memory
(NVRAM) and a battery module. If an NVRAM and a battery are present, the test verifies the
normal operation of these modules.
– Global cache Test — Retrieves the global cache parameters and verifies the normal operation of
this function.
You must stop an application that reserves the RAID controller before you attempt to run the Adaptec
RAID controller diagnostic test or the hard disk diagnostic test. If you do not, the diagnostic reports a
failure with the following message:
An application or service that manipulates RAID such as FAST or
PERC Console has reserved the controller and must be stopped before
running this test. See the Server Administrator online
context-sensitive help or the "Server Administrator CLI User's Guide"
for more information.
NOTE: To stop FAST or the PERC Console, exit the application.
• LSI RAID Controller Hardware Test — Consists of two parts:
– Configuration Test — Tests and verifies the format and content of the configuration data and
compares it to the actual configuration for any discrepancies. Any format violations and
configuration mismatches are reported. Failing this test does not imply that the controller is
defective. Instead, failing this test means that the controller's configuration is not the same as the
data from NVRAM.
– Timer Test — Tests the timer sequence of the RAID controller. Any nonsupported timer sequence
verifications result in a timer test failure. Timer test failures cause the controller to be marked as failed.
• LSI RAID Controller Battery Test — Tests the voltage and temperature on the battery, if one is
present. If this test fails and a battery is installed on your RAID controller, replace the battery. The test
is nondestructive; it does not write data to the storage devices managed by the controller.
