Agent information 60
• OK—Indicates the tape drive is operating normally.
• Failed—Indicates the tape drive has failed and might need to be replaced.
• Offline—Indicates the tape drive is offline and can no longer return data. No further status is available.
• Missing—Was OK—Indicates a tape drive that was located in the system and had a status of OK, which
has been removed.
• Missing—Was Failed—Indicates a tape drive that was located in the system and had a status of failed has
been removed.
• Missing—Was Offline—Indicates a tape drive that was located in the system and had a status of offline has
been removed.
• Unknown—The Storage Agents cannot determine the status of this tape drive. You might need to upgrade
your driver software or Storage Agents.
• Model—Displays a description of the SCSI tape device model as returned by the SCSI inquiry command. Use
this item for identification purposes.
• Firmware Version—Displays the firmware revision level of the tape device as returned by the SCSI inquiry
command.
• Serial Number—Displays the serial number assigned to the tape device. This value is based on the serial
number as returned by the SCSI inquiry command, but might have been shortened because of space limitations.
Use this item for identification purposes.
NOTE: Not all tape devices support serial numbers.
• Placement—Indicates whether 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.
• Library Drive—Indicates whether the tape drive is included in a tape library. The following values are valid:
• Yes—The tape drive is included in a tape library.
• No—The tape drive is not included in a tape library.
• Unknown—The Storage Agents are unable to determine if the tape drive is included in a tape library.
• Media Changer Information—Displays the autoloader media changer information. This only displays when the
tape device is an autoloader.
• Model—Displays a description of the SCSI tape autoloader media changer model as returned by the SCSI
inquiry command.
• Firmware Version—Displays the firmware revision level of the tape autoloader media changer as returned
by the SCSI inquiry command.
• Serial Number—Displays the serial number assigned to the tape autoloader media changer. This value is
based on thee serial number as returned by the SCSI inquiry command.
• Magazine Size—Displays the magazine size of the SCSI tape autoloader media changer.
• Tape Errors—Displays the number of read and write errors that have been encountered with the currently
loaded tape. Over time, a tape device might produce these errors. These errors are usually caused by bad
media sections on the drive. If this value rises dramatically, you might need to clean the device.
NOTE: The number of tape errors is equal to or greater than the combined total for re-reads, re-writes and
uncorrectable errors.
• Re-reads—Displays the number of read errors corrected through tape drive retries. Over time, all drives produce
these errors. If you notice a rapid increase in the value for Recovered Read Errors or Hard Read Errors, a
problem might exist with the drive. The value increases every time the physical drive detects and corrects
another error. If this value rises dramatically, you might need to clean the device.
• Re-writes—Displays the number of write errors corrected through tape drive retries or other drive recovery
mechanisms. Over time, all drives produce these errors.
