Mount history report

The mount history report is saved to a file named <library-name>_mount_history_<date>.csv.

The report contains the following information:

Date and Time

The date and time that the cartridge was mounted into the drive, in the format yyyy mm dd hh:nn.ss.

VolSer

The volume serial number of the cartridge (also known as the VOLSER). The VOLSER is a unique identifier. Ignore the underscore that precedes the VOLSER.

Frame

The number of the library frame from which the cartridge was demounted. Beginning with the base frame, frames are numbered 1 - 4, from left to right.

Drive

The number of the drive from which the cartridge was demounted. Drives are numbered 1 - 16.

LogLib

The name of the logical library to which the cartridge was assigned.

EAddr

The SCSI element address of the drive from which the cartridge was demounted.

Mount Media Write

The total amount of data, in MB, that is written by the drive on that mount.

Mount Media Read

The total amount of data, in MB, that is read by the drive on that mount.

Mount Host Write

The total amount of data, in MB, that is written through the host on that mount.

Mount Host Read

The total amount of data, in MB, that is read through the host on that mount.

Mount Drive Residency

The number of minutes the tape cartridge remained in the tape drive during the mount.

Mount Tape Alert Media

The TapeAlerts (if any) set during that mount.

A maximum of four TapeAlerts are reported in one string with no spaces. Single-digit TapeAlerts include a leading zero. For example, TapeAlerts 5, 12, 29, and 60 would be reported as 05122960.

Life Mounts Media

The number of times the cartridge has been mounted to a drive since it was manufactured.

Life WRetries Media

During the life of the cartridge, the number of errors that occurred when drives retried write operations.

Life WPerms Media

During the life of the cartridge, the number of permanent, unrecoverable errors that occurred when drives performed write operations.

Life RRetries Media

During the life of the cartridge, the number of errors that occurred when drives retried read operations.

Life RPerms Media

During the life of the cartridge, the number of permanent, unrecoverable errors that occurred when drives performed read operations.

Mount Rating Drive

The overall measure of the condition of the drive. X'00' is unknown. The value ranges from X'01' (best) to X'FF' (worst). This is a rating of the efficiency of the drive.

Mount Rating Media

The overall measure of the condition of the cartridge that is mounted. X'00' is unknown. The value ranges from X'01' (best) to X'FF' (worst). This is a rating of the efficiency of the cartridge.

Mount Rating Ports

The overall measure of the condition of the interface to the host server. X'00' is unknown. The value ranges from X'01' (best) to X'FF' (worst). This is a rating of the efficiency of the interface.

Mount Rating Port0

The overall measure of the condition of the Port 0 interface to the host server. X'00' is unknown. The value ranges from X'01' (best) to X'FF' (worst). This is a rating of the efficiency of the Port 0 interface.

Mount Rating Port1

The overall measure of the condition of the Port 1 interface to the host server. X'00' is unknown. The value ranges from X'01' (best) to X'FF' (worst). This is a rating of the efficiency of the Port 1interface.

Mount Rating Rsvd

Reserved for the library interface.

Mount Write Perf

The ratio of performance write commands with respect to all write-type commands. This is a measure of the efficiency of write performance. The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Write ERPs

The measure of how the data rate performance impacts the error-recovery procedures (ERPs) on write operations. The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Write Burst

For write operations, the measure of the comparison between the window tape buffer rate to the average rate. The window rate is the amount of data moved divided by the time when ready in the mode (when data could be moved, but is not). The average rate is the amount of data moved divided by the overall time in the mode (including setup, overhead, and so forth). The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Write Buffer

The average tape-buffer efficiency on write operations. This is streaming write efficiency. The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Read Perf

The ratio of performance read commands with respect to all read-type commands. The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Read ERPs

The measure of how the data rate performance impacts the error-recovery procedures (ERPs) on read operations. The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Read Burst

For read operations, the measure of the comparison between the window tape buffer rate to the average rate. The window rate is the amount of data moved divided by the time when ready in the mode (when data could be moved, but is not). The average rate is the amount of data moved divided by the overall time in the mode (including setup, overhead, and so forth). The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Read Buffer

The average tape-buffer efficiency on read operations. This is streaming read efficiency. The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Capacity Total

The measure of the efficiency of static capacity. This can be viewed as the percentage of recorded media that fits into the currently recorded area with respect to how much data can ideally fit in that area. The lower the percentage, the less capacity is available (due to recording error recovery, media defects, and so forth).

Mount Capacity Writes

The measure of the efficiency of active capacity on write commands. This can be viewed as the sum of efficiency for write operations on this mount. The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Capacity Control

The measure of the efficiency of active capacity on all other operations. The value is given as a percentage. A high percentage is best; a low percentage is worst.

Mount Crypto Status

Whether a cartridge is encrypted. Values are 1 (the media contains encrypted data), 0 (the media does not contain encrypted data), or a blank space if the drive was unable to determine whether the media contains encrypted data.

Crypto Rekey

Whether a cartridge has been rekeyed. Values are 1 (the cartridge was rekeyed during the last mount) or 0 (the cartridge was not rekeyed during the last mount).
