Third-party SCSI Controller Model

Unknown—The driver software or storage agents might need to be upgraded, or you have a SCSI

controller in the system that the Storage Agents do not recognize.

Status—Displays the current status of the controller. The following values are valid:

OK—The controller is operating normally.

Failed—The controller has failed and is no longer operating.

Unknown—You might need to upgrade your driver software or Storage Agents or the Storage Agents

cannot determine the status of the controller.

Serial Number—Displays the serial number of the SCSI controller. This number can be used for identification

purposes.

Firmware Version—Displays the SCSI controller’s BIOS firmware version number. This information is not

available for all SCSI controllers.

Bus Width—Displays the physical width of the data transfer bus of the SCSI controller. The following values are

valid:

Narrow (8 bits)—The controller supports a narrow 8-bit data transfer bus.

Wide (16 bits)—The controller supports a wide 16-bit data transfer bus.

Unknown—The agent is unable to determine the physical width of the data transfer bus. You might need to

upgrade your software.

Hard Resets—Displays the number of times the SCSI Hardware Interface Driver detected that the SCSI bus has

been reset since the driver was loaded.
Hard resets occasionally occur due to device errors. If this value rises dramatically, there might be a problem.

Review the SCSI bus information for unusually high error counts. A device with a large number of bus errors

might be failing and require replacement.

Soft Resets

—Displays the number of times the SCSI Hardware Interface Driver has issued a reset command to all

devices on a SCSI bus since the driver was loaded. Soft resets occur when the device driver is initializing the

SCSI bus for operation or when device errors have left the bus in an ambiguous, nonoperational state.
If this value rises dramatically, there might be a problem. Review the SCSI Bus Information for unusually high

error counts. If there is a device with a large number of bus errors, it might be failing and require replacement.

Timeouts—Displays the number of times the SCSI Hardware Interface Driver issued a SCSI command but did not

receive a reply within a specific amount of time. This 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. However, if this

value rises dramatically, there might be a problem. Verify that non-disk SCSI devices (such as tape drives) reside

on the SCSI bus with the drives. Non-disk devices can require the SCSI bus for long periods, resulting in

timeouts.

SCSI device information

The information displayed for each SCSI device entry in the submenu includes condition graphic, location (SCSI ID),

and device type. Select any of the physical devices from the submenu to display more information about the device.
The following information is a list of device types and the information displayed for all SCSI devices:

Device Type—Identifies the type of SCSI device. The following values are valid:

Disk—A direct-access device, such as a disk drive.

Removable Disk—A removable media device, such as a floppy disk drive.

Tape—A sequential-access device, such as a tape drive.

Printer—A printer device.

Processor—An operating device, such as a central processing unit or ProLiant Storage System.

WORM drive—A write-once, read-many times device.

DVD/CD-ROM—A DVD-ROM or CD-ROM device. It can be a read-only device or read-write device.
