HP Insight Management Agents - Manual (Page 89)

◦ The StorageWorks Library Adapter
◦ 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.
