32 omdiag: Using the Diagnostic Service
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 Array
Manager, 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 the Array Manager service on a system running Microsoft Windows, go to the Control Panel, select
Services, right-click the Disk Management Service, and select Stop. 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.
• Adaptec and LSI Array Disk Test — Tests the hard drives on your system. You can test hard drives
attached to a system through a qualified Adaptec or LSI RAID controller and determine if the drives
have failed. This test verifies a drive's ability to respond to commands, return diagnostic information,
and ensure data integrity across the entire hard-drive surface.
• Identify Connected Disks —Ensures that the SCSI subsystem between the controller and the
connected device is intact. The Identify Connected Disk test is only available if the Adaptec and/or
LSI controller have devices connected to them.
NOTE: The hard disk diagnostics are designed to run as a low-priority background task to limit the effect on I/O.
Because of their low priority, it is recommended that you limit hard disk activity while running the diagnostics. The
diagnostics may run slowly or even stop while hard disk I/O activity is running simultaneously.
