2.9.2 DESCRIPTION

This FSE command manages a single FSE medium. It is used to perform these

FSE administrator’s tasks:

• conﬁgure a new or remove an existing FSE medium,

• list barcodes and status information for conﬁgured media in the FSE imple-

mentation,

• show status information for medium volumes on conﬁgured FSE media,

• format and/or initialize a conﬁgured FSE medium,

• change an FSE medium status to unreliable, unusable, or remove either of

these two statuses (change the status to "good"),

• mark an FSE medium volume as full and handle its Fast Recovery Informa-

tion appropriately,

• recreate missing Fast Recovery Information on disk from the migrated

meta– data,

• duplicate a medium to a medium of the same tape (copy all data and Fast

Recovery Information from the source to the target medium),

• reorganize a medium or speciﬁed medium volumes preserving only the data

that was determined as valid during the reorganizational scan job,

• recreate a redundant copy of the unreadable data located on damaged FSE

media.

Each FSE command communicates with the FSE processes through the Manage-

ment Interface (fse–mif). To execute an FSE command, the Management Interface

must be running. If the connection to the Management Interface fails, check its

status by running the fse ––status command. In case the Management Interface

is not running, start it with the fse – –start command.

After a successful command execution fsemedium notiﬁes the FSE administrator

with a suitable message, which is printed to the standard output stream (stdout).

If there was an error during the command execution, an appropriate error message

is printed to the standard error stream (stderr).
