Operating ETERNUS CS requires special ROBAR rule files which differ from the usual ROBAR rule files in the following points:
No rewind time. ETERNUS CS allows a virtual volume to be unmounted directly after the operator has issued an UNLOAD. This also applies to “manual” unload procedures (
ULU
statement) performed by the operator when an accessing problem occurs (i.e.KE
generally immediately afterULU
).Reduced waiting time while checking the MTC header (tape label) during mounting.
Device cleaning for real tape drives is controlled by ETERNUS CS, so device cleaning no longer features in the ROBAR rule file.
Volume import or export of MTCs are not possible.
Foreign volumes are unknown.
“Fast mount” support (see section "Fast mount support" in chapter "Mounting cartridges") via
CVA
statement.
ROBAR only acknowledges MOUNT statements for initializations. In this case a “fast mount” request is issued to ETERNUS CS and the waiting time for the acknowledgment to be received is adjusted to the short reaction times of ETERNUS CS.
