General Comment

People in garching is expecting to receive at least one disk almost every week, we MUST bear in mind that they need the data over there so we CAN NOT wait and keep the disks here. As soon as one set of disks is full, the Main disk has to be shipped off in the next diplo-bag, even if this means that you have to send a single disk in a big Peli-case.

Instructions

Upon Arrival:

• Open up the Peli-case and check that the disks have arrived safely.
• Update and add comment (if necessary) on the NGAS Operators Log Book
• Update the status of the disks (e.g. in Garching, in La Silla, etc.) on the disk_status page.
• Store them on the 2.2 computer room at the RITZ, place them on the upper wooden shelf.
• If you ever run out of NGAS Disks (or you are close to) send an e-mail to Operations Technical Support - Science Archive Operations requesting more.

Check NGAS magnetic disks status. NGAS Status. Once a set of Disks is full:

• Do not change a NGAS disk before the night is over (12UTC).
• Do not change a NGAS disk before letting La Silla Archive (Anton or Blanca) know.
• Remove the set from w2p2nau, following the stablished NGAS Disks Exchange procedure.
• Put the Main disk into the Peli-case and get it ready for the next diplo-bag.
• Give the Replica removed from the w2p2nbu to Data Handling.
• Update and add comment (if necessary) on the NGAS Operators Log Book
• Update the status of the disks (e.g. in Garching, in La Silla, etc.) on the disk_status page.

NOTE

The ngast@eso.org e-mail should always be used if there are problems with the system. Such problems should be reported immediately and you should not hesitate to report even minor things if you have doubts about the correctness of the archiving process. This includes problems with deleting data and the whole DFS data flow.
