Note:
This field links to the Exchanges Overview screen, list view, which lists this drive's exchanges. See "Exchanges Overview Screen".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 – An error has occurred with the cartridge memory; this results in reduced performance.
CLEAN_REQ – The drive is due for cleaning.
DRIVE_ERROR – The drive has experienced a hardware or microcode error.
ENCRYPT_ERROR – An error has occurred with the encryption key management system. This is neither a drive nor media problem, so there is no effect on the suspicion of the drive or media.
Possible causes for this status include the following: compromised network connectivity to the encryption key server; the encryption key server is down; the drive key enrollment has expired and the drive must be re-enrolled; either the drive or the media is not encryption-capable. It may be possible for the drive to read unencrypted media until the encryption issue is resolved.
EXPIRED_CLEAN_TAPE – The cleaning media has expired.
FAILED_MOUNT
FATAL_ERROR – The media cannot be mounted or is stuck. Possible reasons include a problem with the drive hardware or the media cartridge.
FW_DOWN_LEVEL – The drive firmware is downlevel.
GOOD – The exchange completed with no issues.
INCOMPLETE_UNLOAD – The application requested that the media be unloaded. The drive has detected data still in its buffer and has asked for confirmation from the application.
INVALID_OPERATION – The host has requested an invalid operation, such as any of the following: mounting media in an incompatible drive; reading from media that is blank; writing on media that is write-protected; attempting to locate a position beyond the beginning or end of the tape.
LOAD_ERROR – An issue with the media prevented it from being loaded. Possible causes include: a problem with the drive hardware or microcode; a problem with the cartridge leader.
LTO_NON_ADI_MODE –ADI mode has not been enabled on either the library, the drive, or both.
MEDIA_ERROR – The media cannot be read or written. Possible causes include a problem with the tape medium or the MIR.
NON_DRV_ERROR – This is neither a drive nor media problem, so there is no effect on the suspicion of the drive or media. For additional information, check the following: for Enterprise drives, check the exchange fault symptom code (FSC); for LTO drives, check recent tape alerts.
Possible causes for this status are as follows:
* A Media Write Protect Tape Alert must be set. The host application is attempting to write to media that has been write protected.
* FSC has been set to 3627, 3629, 362A, or 362B. These FSC codes are set during a "normal operation," which checks that a piece of media is truly blank before labeling it. The host application will perform the following sequence: 1) mount new tape; 2) attempt to check for no label; 3) label the new tape.
OTHER_DRV_ERROR
OTHER_ERROR
PERM_ERROR – A permanent error occurred on the exchange. This may be the result of a media format error, possibly from a previous exchange.
READ_ERROR – The media could not be read. Possible causes include: a problem with the drive hardware or microcode; a problem with the media MIR; the media may have been corrupted during a previous mount; the drive and media may be incompatible
UNKNOWN – 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.
UNLOAD_ERROR – An error occurred during the unload operation. Possible causes include: a problem writing to the media RFID or MIR; the drive and media may be incompatible.
WRITE_ERROR – An error occurred during the write operation. Possible causes include: a problem with the drive hardware or microcode; the media may have been corrupted during a previous exchange; the drive and media may be incompatible.
Drive firmware and host interface level. See the STA Requirements Guide for details on whether this firmware version supports rich data for STA.
Drive health as computed by STA analytics. This is a point-in-time value based on data gathered from the drive during current and past exchanges. It reflects a variety of factors, such as the drive'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 the drive.
Possible values, in order of degrading health:
USE – The drive has had no failures or degradation in the last ten exchanges
MONITOR – The drive has had multiple errors; there is a less than 80 percent chance that it needs service.
EVALUATE – The drive has had multiple errors; there is a greater than 80 percent chance that it needs service.
ACTION – The drive has had an error that requires attention. The drive may require service. You should investigate and determine a proper course of action.
UNKNOWN – STA has not received enough data to compute health for the drive. This may be due to a variety of factors, including an unsupported drive model, downlevel drive firmware, or ADI mode not enabled for an LTO drive.
Note:
STA only receives information about errors detected by a drive while performing read/write activity to a media. STA does not receive information about errors that may occur in the data path or the host application.Note:
Cleaning exchanges have a neutral impact on drive health.Note:

If this alert appears multiple times for the same volser, it is likely there is more than one physical media with the same media type and volser label in the tape environment. If it only appears once for the volser, it may be that the volser label from a retired media has been re-used on a new media.

Percentage of the media's expected useful life that has elapsed
Status of the media upon completion of the exchange, as derived from a variety of factors, including media errors, write efficiency, and read margin. Possible values:
CART_MEM_FAILURE – An error has occurred with the cartridge memory; this results in reduced performance.
CLEAN_REQ – The drive is due for cleaning.
DRIVE_ERROR – The drive has experienced a hardware or microcode error.
ENCRYPT_ERROR – An error has occurred with the encryption key management system. This is neither a drive nor media problem, so there is no effect on the suspicion of the drive or media.
Possible causes for this status include the following: compromised network connectivity to the encryption key server; the encryption key server is down; the drive key enrollment has expired and the drive must be re-enrolled; either the drive or the media is not encryption-capable. It may be possible for the drive to read unencrypted media until the encryption issue is resolved.
EXPIRED_CLEAN_TAPE – The cleaning media has expired.
FAILED_MOUNT
FATAL_ERROR – The media cannot be mounted or is stuck. Possible reasons include a problem with the drive hardware or the media cartridge.
FW_DOWN_LEVEL – The drive firmware is downlevel.
GOOD – The exchange completed with no issues.
INCOMPLETE_UNLOAD – The application requested that the media be unloaded. The drive has detected data still in its buffer and has asked for confirmation from the application.
INVALID_OPERATION – The host has requested an invalid operation, such as any of the following: mounting media in an incompatible drive; reading from media that is blank; writing on media that is write-protected; attempting to locate a position beyond the beginning or end of the tape.
LOAD_ERROR – An issue with the media prevented it from being loaded. Possible causes include: a problem with the drive hardware or microcode; a problem with the cartridge leader.
LTO_NON_ADI_MODE –ADI mode has not been enabled on either the library, the drive, or both.
MEDIA_ERROR – The media cannot be read or written. Possible causes include a problem with the tape medium or the MIR.
NON_DRV_ERROR – This is neither a drive nor media problem, so there is no effect on the suspicion of the drive or media. For additional information, check the following: for Enterprise drives, check the exchange fault symptom code (FSC); for LTO drives, check recent tape alerts.
Possible causes for this status are as follows:
* A Media Write Protect Tape Alert must be set. The host application is attempting to write to media that has been write protected.
* FSC has been set to 3627, 3629, 362A, or 362B. These FSC codes are set during a "normal operation," which checks that a piece of media is truly blank before labeling it. The host application will perform the following sequence: 1) mount new tape; 2) attempt to check for no label; 3) label the new tape.
OTHER_DRV_ERROR
OTHER_ERROR
PERM_ERROR – A permanent error occurred on the exchange. This may be the result of a media format error, possibly from a previous exchange.
READ_ERROR – The media could not be read. Possible causes include: a problem with the drive hardware or microcode; a problem with the media MIR; the media may have been corrupted during a previous mount; the drive and media may be incompatible
UNKNOWN – 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.
UNLOAD_ERROR – An error occurred during the unload operation. Possible causes include: a problem writing to the media RFID or MIR; the drive and media may be incompatible.
WRITE_ERROR – An error occurred during the write operation. Possible causes include: a problem with the drive hardware or microcode; the media may have been corrupted during a previous exchange; the drive and media may be incompatible.
Media health as computed by STA analytics. This value reflects a variety of factors, such as the media's error history, read margin, and write efficiency. It includes all data up to and including the last completed exchange and is updated immediately upon completion of the exchange.
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.Trend of media health between the last two exchanges, as computed by STA analytics. Options are: BETTER, UNCHANGED, WORSE.
