Initializing Tapes (TSIDINIT) Mounting Tapes
12-12 User Reference
In this example, TSIDINIT performs sequential initialization of uncontrolled tapes that have
labels or tape marks. It initializes the first tape with the volume serial number EP0001, the
second tape with EP0002, the third tape with EP0003, and so on until the operator stops the
process. It does label checking to ensure that the tape does not contain an active dataset. It
also checks the DSN Catalog to ensure that there is no duplication of volume serial number
before it initializes each tape.

In this example, TSIDINIT performs random initialization of uncontrolled tapes that do not
have labels or tape marks. It initializes the first tape with the volume serial number PR0001,
the second tape with PR0024, the third tape with PR0047. It does not prevent duplication of
volume serial number and does not do label checking to ensure that the tapes mounted are
valid scratch tapes.

In this example, TSIDINIT uses an ACL to do sequential initialization of tapes not in the
EPIC Catalog that have labels or tape marks. It initializes the first tape with volume serial
number SR0010, the second with SR0011, and so on until 10 volumes have been initialized.
(SR0010 through SR0019)

In this example, TSIDINIT uses an ACL to do random initialization of tapes not in the EPIC
Catalog that have labels or tape marks. It initializes the first tape with volume serial number
JCSR09, the second with WXY981, and so on until all volume serial number specifications
have been read.
