Cleaning Activity

Volume serial number (VSN or volser) assigned to the media by its external label. If the library does not supply the volser, STA provides one composed of Library Serial Number:Physical Address.

Note – This field links to the Media – Overview screen, detail view, which displays all available detail for this media. See “Media Overview and Analysis Screens”.

Media Health Indicator

Media health. This is a point-in-time value computed by STA analytics. It reflects a variety of factors, such as the media’s error history, read margin, and write efficiency.

This value includes all data up to and including the last completed exchange. It is updated immediately after each completed exchange involving this media.

Possible values, in order of degrading health:

•	USE – The media has had no failures or degradation in the last ten exchanges.

•	MONITOR – The media has had multiple errors; there is a less than 80 percent chance that it needs service.

•	EVALUATE – The media has had multiple errors; there is a greater than 80 percent chance that it needs service.

•	ACTION – The media has had an error that requires service.

•	UNKNOWN – STA has not received enough data to compute health for the media. This may be due to a variety of factors, including exchanges on unsupported drive models, drives with downlevel firmware, or LTO drives with ADI mode not enabled.

Note – STA only receives information about errors detected by a drive while performing read/write activity to the media. STA does not receive information about errors that may occur in the data path or host applications.

MB Between 2 Most Recent Cleans

Total megabytes read and written by the drive between the two most recent cleanings.

Current Cleaning Uses

Total number of times the cleaning media has been mounted in a drive since STA began monitoring the media.

Maximum Cleaning Uses

Manufacturer's recommended usage limit for the cleaning media.

Note – Not available for all media and drive types. This value may show as “0” or blank, which should be interpreted as not available or unknown.

Cleaning Media Expired

The drive firmware has determined that the cleaning media has already been used the maximum number of times and cannot be used for this cleaning exchange.

Exchange Start

Date and time when the drive was reserved for the exchange or cleaning operation.

Note – This field links to the Libraries – Exchanges screen, detail view, which displays all available detail for this exchange. See “Exchanges Screen”.

Exchange End

Date and time when the exchange completed

Exchange Elapsed Time

Total time the drive was reserved for the exchange. Starts at the beginning of the mount move and ends at the completion of the dismount move. Includes total mount time plus total transit time immediately before and after the mount. Displayed in hh:mm:ss format.

Exchange Mount Time

Total time the media was mounted in the drive. Includes the total time between the start of the mount and the start of the dismount. Does not include transit time before and after the mount. Displayed in hh:mm:ss format. If this attribute is blank, then it is likely that STA did not receive all the exchange data from the library.

Drive Exchange Status

Status of the drive upon completion of the exchange, as derived from a variety of factors, including drive errors, write efficiency, and read margin. Possible values:

•	CART_MEM_FAILURE

•	CLEAN_REQ – The drive is due for cleaning.

•	DRIVE_ERROR

•	EXPIRED_CLEAN_TAPE

•	FAILED_MOUNT

•	FW_DOWN_LEVEL

•

GOOD

•	INCOMPLETE_UNLOAD – The application requested that the media be unloaded. The tape drive has detected data still in its buffer and has asked for confirmation from the application.

•	INSUFFICIENT_DATA(NULL) – STA has not received enough exchange data from the library to calculate drive health. It may be that the drive is not supported (LTO 2, for example) or the library firmware is downlevel.

•	LOAD_ERROR

•	LTO_NON_ADI_MODE – ADI mode has not been enabled on either the library, the drive, or both.

•	MEDIA_ERROR

•	NON_DRV_ERROR – This is neither a drive nor a media problem, so there is no effect on the suspicion of drive or media.

•	OTHER_ERROR

•	PERM_ERROR

•	READ_ERROR

•	WRITE_ERROR

•

UNKNOWN

•	UNLOAD_ERROR

Exchange FSC

Four-byte hexadecimal fault symptom code (FSC). For example, FD55, S053, etc. Reported only if an error occurred during the exchange.
