S.M.A.R.T. Support—Indicates if S.M.A.R.T. support is available for this SCSI drive. The
following values are valid:

Not Available—Predictive failure monitoring is not available for this drive.

Available—This drive supports predictive failure monitoring.

Unknown—The Storage Agents cannot determine if the drive supports predictive failure
monitoring. You might need to upgrade your driver or Storage Agents.

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:
