The STACK function takes a number of specified tapes, either labeled or unlabelled, and copies data from all tapes onto a single stacked tape.
STACK also supports heterogeneous media translation. This occurs when a tape is stacked to a tape media that is different from the media of the original tape volume.
Examples
The following are examples of commands using the STACK function:
-
U TSU STACK UNITNO=91 (FIRST), “J1”, SERIALNO=1 (THIRD) TO UNITNO=94
-
U TSU STACK “J1”, UNITNO=92 (COMMENT), J2 TO “MYSN”
-
U TSU OUTFILE=PRINTER STACK UNITNO=91 TO UNITNO=93
-
U TSU OUTFILE=”(TRANSFER)STACK/OUTPUT ON MISC.” STACK J1 TO “MYSN”
-
U TSU STACK 001-004 TO “MYSN”
-
U TSU STACK UNITNO=91, UNITNO=92 TO UNITNO=93
-
U TSU STACK UNITNO=91* TO UNITNO=93
Sample Run
The following is an example of the output of a STACK run. The tape MYSTK was assigned a serial number and scratched before this utility ran. No user intervention was required during this example.
U TSU STACK UNITNO=96 (FEW SMALL FILES HERE IN), UNITNO=93,UNITNO=94 (UL TAPE) TO #RUNNING 62017 CREATING STACKED TAPE [MYSTK ] ON MT95 SUCCESSFULLY STACKED [JL1 ] FROM MT96 (FEW SMALL FILES HERE) SUCCESSFULLY STACKED [JL2 ] FROM MT93 SUCCESSFULLY STACKED (UNLABELED) FROM MT94 (UL TAPE) STACK COMPLETED TO STACKED TAPE [MYSTK ] ON MT95 #ET=25.7 PT=0.4 IO=14.7
The following is the P MT listing following the previous STACK example. The stacked tape is labeled MYSTK and has the file name TSU/STACKEDTAPE.
P MT ---------------------------------- MT STATUS ------------------- 93 H [JL2 ] 38000 #1 1:0 <10/29/2003> JL2/FILE000 94*H 38000 UNLABELED 95H [MYSTK ] 38000 #1 1:0 <11/21/2003> TSU/STACKEDTAPE 96 H [JL1 ] 38000 #1 1:0 <10/27/2003> JL1/FILE000
