Status displays the status of the tape storage system. The following values are valid:Serial Number displays the unit serial number for the tape library. Use this value for identification purposes.
OK - Indicates that the library is operating normally.
Degraded - Indicates the library has degraded in some manner.
Failed - Indicates the library has failed and can no longer return data. The library may need to be replaced.
Offline - Indicates the Storage Agents can no longer communicate with the library. This could be caused by a cabling problem or the library may be powered off.
Unknown - The state of the tape library cannot be determined. You may need to upgrade the Storage Agents.
Door Status displays the status of the door. The following values are valid:
Total Moves displays the number of tape moves for the library loader arm.
Not Supported - The door status is not supported by the device.
Closed - The door is closed.
Open - The door is open.
Unknown - The state of the tape library door cannot be determined. You may need to upgrade the Storage Agents.
Model displays the model name of the tape library. Use this value for identification purposes.
Firmware Revision displays the firmware revision level of the tape library. The level can be used for identification purposes.
Service Hours displays the number of hours of operation for the library.
Last Known Error displays the last error returned by the tape library.
Associated Tape Drives displays a list of tape drives associated with the tape storage system.
Select one of the tape drive entries from the Mass Storage submenu to display the following information about that drive.
Status displays the status of the tape drive. The following values are valid:Model displays the model name of the tape drive. Use this value for identification purposes.
OK - Indicates the tape drive is operating normally.
Degraded - Indicates the tape drive has degraded in some manner.
Failed - Indicates the tape drive has failed and can no longer return data. The tape drive may need to be replaced.
Offline - Indicates the Storage Agents can no longer communicate with the tape drive. This could be caused by a cabling problem or the tape drive may be powered off.
Missing - Was OK - Indicates that a tape drive that was located in a Compaq System and had a status of OK has been removed.
Missing - Was Offline - Indicates that a tape drive that was located in a Compaq system and had a status of offline has been removed.
Unknown - The state of the tape drive cannot be determined. You may need to upgrade the Storage Agents.
Firmware Revision displays the firmware revision level of the tape drive. Use this value for identification purposes.
Serial Number displays the unit serial number for the tape drive. Use this value for identification purposes.
Library Drive indicates whether the tape drive is included in a tape library. The following values are valid:
Hot Plug indicates whether the tape drive supports hot plug replacement. 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.
Yes - The tape drive supports hot plug replacement.
No - The tape drive does not support hot plug replacement.
Unknown - The Storage Agents are unable to determine if this drive supports hot plug replacement.
Tape Errors displays the total number of read and write errors encountered. This value is maintained from the moment the Tape Hardware Interface driver was loaded.Tape errors may occasionally occur. If this value rises dramatically, clean the device. If you continue to have errors, you may have a problem. Some common causes of tape errors include radio frequency interference (RFI) on the bus cables, bad or missing terminating resisters on the drives, or having more than one device with the same SCSI ID. Ensure the bus cable is free of obstructions and that the devices on the bus are properly configured.
Uncorrectable displays the total number of read and write errors that could not be corrected. This value is maintained from the moment the Tape Hardware Interface driver was loaded.
Uncorrectable errors may occasionally occur. If this value rises dramatically, clean the device. If you continue to have errors, you may have a problem. Some common causes of uncorrectable errors include radio frequency interference (RFI) on the bus cables, bad or missing terminating resisters on the drives, or having more than one device with the same SCSI ID. Ensure the bus cable is free of obstructions and that the devices on the bus are properly configured.
Rereads displays the number of times blocks that had to be reread from the device. This value is maintained from the moment the Tape Hardware Interface driver was loaded.
Reread errors may occasionally occur. If this value rises dramatically, clean the device. If you continue to have rereads, you may have a problem. Some common causes include radio frequency interference (RFI) on the bus cables, bad or missing terminating resisters on the drives, or having more than one device with the same SCSI ID. Ensure the bus cable is free of obstructions and that the devices on the bus are properly configured.
Rewrites displays the number of times blocks that had to be rewritten to the device. This value is maintained since the Tape Hardware Interface driver was loaded.
Re-write errors may occasionally occur. If this value rises dramatically, clean the device. If you continue to have rewrites, you may have a problem. Some common causes include radio frequency interference (RFI) on the bus cables, bad or missing terminating resisters on the drives, or having more than one device with the same SCSI ID. Ensure the bus cable is free of obstructions and that the devices on the bus are properly configured.
Tape Drive Heads Need Cleaning indicates whether the tape drive heads need to be cleaned. To clean the tape heads, insert a cleaning tape into the device and run through a cleaning cycle.The following values are valid:
Cleaning Tape Needs Replacement indicates whether the cleaning tape that is inserted in an autoloader needs to be replaced because its cleaning capability is exhausted (it is at the end of the tape).
Yes - The tape drive requires a cleaning tape session in order to clean the heads.
No - The tape drive does not require any cleaning tape session.
Not Supported - The tape drive does not support monitoring of the cleaning required status.
This variable can be in one of the following states:
Yes - The autoloader tape drive requires a new cleaning tape to be inserted.
No - The tape drive does not require a new cleaning tape.
Not Supported - The tape drive does not support monitoring of the cleaning tape replacement status.
NOTE: This variable is only applicable to autoloader tape drives.
