What is Data Pump?
Etere HSM - Data Pump manages the operations scheduled from the headquarters application for a specific tape drive. Etere HSM Data Pump uses a local cache to speed up the operation, and this local cache must be greater than the size of the tape. The local cache path must be configured in the Tape Drive Configuration before accessible.
Each drive managed by the robotics library must be controlled by a dedicated instance of Etere HSM - Data Pump, which should be installed on the server that connect through SCSI to the tape drive (that server can be different from the library server). Please note that is possible to run various Data Pump instances on the same computer (the maximum number of total data pump instances is determined by the number of licensed tape drives).
In a controlled environment, you might require administrator rights to use HSM Data Pump for Archive/Restore operations, simply right-click on the shortcut icon in desktop and enable the privilege level to "Run the program as an administrator".
NB: To reduce the transaction counts logging in the DataPump workflow log, the workflow logging would only log one transaction count on the last bundled assets to prevent huge file size.
How to use Data Pump?
In this chapter, the operator will find the information necessary to correctly use Etere HSM - Data Pump, including the following sections:
•Main user interface
•Load/Unload tape
•Maintenance mode
What does Data Pump do in case of errors on tapes?
Every time Etere Data Pump encounters a read or write error during a tape operation, one of the following actions will automatically performed:
•Write error: the tape will be automatically set as "with error", thus avoiding future unsuccessful writing attempts.
•Read error: the tape will be automatically set as "unusable", thus avoiding future unsuccessful reading (and writing) attempts.
NB: Flags (i.e. read-only, with errors, unusable) can be manually modified at any time for single tapes under the Tape Library > Tape information module.
