1. Ensure that all system and storage system cables are intact and seated properly. You

might need to replace the cables.

2. Be sure that the ProLiant Storage System is plugged in and powered on. Be sure the power

supply is functioning.

3. Check the physical proximity of the system to other electrical devices. Because electrical

noise might cause a timeout error, check the AC circuit for other electrical devices.

4. Timeouts can be caused when two or more drives are set to the same SCSI ID. Be sure

that the ProLiant and system SCSI IDs do not conflict.

5. On a ProLiant Storage System, check the SCSI ID cable on the drive tray. If the cable is

damaged or incorrectly installed, SCSI Timeouts can occur. For more information, see

the documentation accompanying the Hot-Plug Drive Tray Service Spare Kit.

6. Be sure that the system temperature is within specified limits. Be sure that fans are operating

and are not blocked.

In some instances, drive failure can cause timeouts. If you continue to receive many of these

errors, replace the drive.

• Problem Indicator—Use this utility to determine when a drive failure has occurred that might

be correctable without replacing the drive. If the drive has failed and the problem indicator

is non-zero, place your cursor over the field and press the F1 key. The context-sensitive Help

for the item includes information on correcting the problem.

• Failure Indicator—Use this utility to determine the cause of failure for a failed drive. If the drive

has failed and this counter is non-zero, replace the drive. If the drive condition is OK and the

failure indicator is not zero, the drive might have an intermittent problem and you might have

to replace it. There is no other corrective action for this error.

• Self-Test Errors—Displays the number of times that a physical drive failed its self-test. The

physical drive does a self-test each time the system is turned on. The number of self-test errors

is counted from the time shown in the Service Hours item on the SCSI Physical Drive window.

If the self-test error count is not zero and the drive has failed, replace the drive. If this count

is non-zero, but the drive has not failed, it could signal an intermittent problem with the drive.

If the number of errors increases over time, replace the drive.

Drive statistics

Select a SCSI physical drive from the SCSI controller submenu to display statistics about a specific

SCSI physical drive. You can use the run-time statistics to monitor the health of a specific drive.

The following information displays:

• Sectors Read—Displays the total number of sectors read from the physical disk drive since the

time listed in the Service Hours item in the SCSI Physical Drive section.

• Sectors Written—Displays the total number of sectors written to the physical disk drive since

the time listed in the Service Hours item in the SCSI Physical Drive section.

NOTE: If sectors read and written are always zero or N/A on Microsoft Windows 2000

you must install Service Pack 2 or higher. You also must enable the logical and physical disk

performance counters. Run DiskPerf.exe -Y in a command window and then reboot the

system.

• Hard Read Errors—Displays the number of read errors that could not be recovered by a

physical drive’s ECC algorithm, retries, or any other recovery mechanism. These errors are

counted over the time listed in the Service Hours item in the SCSI Physical Drive section.

Over time, a drive might produce hard read errors. These errors are usually caused by bad

media sections on the drive.
