I use SEQNBR(1) CLEAR(*ALL) on the first save in the backup (SAVSECDTA) -
AFTER I have checked that the correct tape volume is inserted.
A brief code snippet on how to check the volume id of the mounted tape:
DCL VAR(&CHKTAP) TYPE(*LGL) VALUE('1') /* 1 = +
CHKTAP not run; 0 = CHKTAP already run */
DCL VAR(&MSGID) TYPE(*CHAR) LEN(7)
DCL VAR(&MSGDTA) TYPE(*CHAR) LEN(100)
DCL VAR(&MSGKEY) TYPE(*CHAR) LEN(4)
DCL VAR(&TAPEDEV) TYPE(*CHAR) LEN(10) +
VALUE(TAP01) /* Device name defaulted to +
TAP01. */
DCL VAR(&TAPEDEVB) TYPE(*CHAR) LEN(50)
DCL VAR(&TAPVOLID) TYPE(*CHAR) LEN(6)
/* CHECK THAT TAPE DRIVE IS READY WITH CORRECT TAPE. */
/* (Volume ids for Nightly Backup tapes begin with: */
/* DCMONn, DCTUEn, DCWEDn, DCTHUn, DCFRIn, DCSATn, DCSUNx (n=seq #).*/

Question For Backup Automation
Trying to automate nightly backups but running into a problem when save
command first executes. OS is reporting "an active volume is found" and
wants a reply (c, i, r). I am rotating 5 tapes each week so there is stuff
on each tape when the backup is initiated. I know if an INZTAP command
precedes the save operation, the problem is solved but...
is there any way to avoid this message under these circumstances without
having to do the INZTAP?
Thanx.
