• Placement—Indicates if the physical drive is in an internal or external storage system. The

following values are valid:

— Internal—The physical drive is in an internal storage system.

— External—The physical drive is in an external storage system.

— Unknown—The physical drive is not in a storage system or the Storage Agents cannot

determine the drive placement.

—This symbol indicates that the drive is a hot-plug drive.

• Rotational Speed—Indicates the rotational speed of the drive in revolutions per minute.

• OS Assigned Name—Displays the operating system name associated with the disk drive.

Drive indicators

Select a SCSI physical drive from the SCSI controller submenu to display information on actions

to take when a SCSI physical drive is not operating properly.

Use the Predictive Indicators to predict that a drive is now operating normally, might need to

be replaced. The numerical data associated with these items displays after the item name. For

example, “Used Realloc: 122” indicates that there are 122 used reallocation sectors for this drive.

The Predictive Indicators are as follows:

• Used Reallocs—Displays the number of sectors of the reallocation area that have been used

by the physical drive.

Because of the nature of magnetic disks, certain sectors on a drive might have media defects.

The reallocation area is part of the drive that the drive manufacturer sets aside to compensate

for these defects. The controller writes information addressed from these unusable sectors

to available sectors in the reallocation area. If too many sectors have been reallocated, there

might be a problem with the drive. The number of reallocation sectors reserved for this

purpose is drive-specific, and you must contact the drive vendor for these values.

• Spinup Time—Monitors the time it takes for a physical drive to spin up to full speed.

Drives require time to gain momentum and reach operating speed. As cars are tested to go

from 0 mph to 60 mph in X number of seconds, drive manufacturers have preset expectations

for the time it takes the drive to spin to full speed. Drives that do not meet these expectations

might have problems. If this value increases over time, the drive might be having problems

spinning up. Replace the drive as a precaution.

The spinup value is shown in tenths of a second. If the drive takes 12 seconds to spin up,

the value would be 120. The value might be 0 if you are monitoring a physical drive and

you use a warm boot to reset the system. During a warm boot, the drives continue to spin.

• Timeouts—Displays the number of times that the SCSI Hardware Interface Driver issued a

SCSI command but did not receive a reply within a specific amount of time. The count is

kept from the time the driver was loaded. Timeouts might occur when a device fails to

process a request because the SCSI bus was busy.

If the count is greater than zero and the drive has failed, complete the following steps to

attempt to correct the problem without replacing the drive:

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.
