Stager commands/statuses

These stager commands are useful for production managers and/or batch job submissions (i.e. pre-staged files)

stager* - manage/query file metadata

stager_qry - get current state

stager_get - bulk transfer (several files together => efficient on tapes)

 

The queries on stager return the status of a file in the system, in particular if the file is on DISK or on TAPE

STAGEIN - the file is being recalled from tape or being internally disk-to-disk copied from another diskpool

STAGED - the file has been successfully staged from tape and it is available on disk, or the file is only available on disk if its associated nbTapeCopies = 0

STAGEOUT - the file is opened by the client, who is writing. Have to wait for the client to finish.

CANBEMIGR - the file is on disk and any transfer from client has been completed. The migrator will take it for tape migration.

INVALID  - the file has no valid diskcopy/tapecopy, or a failure happened concerning the file.
