Mounting Tapes Initializing Tapes (TSIDINIT)

Chapter 12. Managing Tape Volumes 12-11

PARM='CONSOLE' can be specified on the VSE EXEC statement to allow the operator to

control initialization. This has exactly the same effect as entering EXEC TSIDINIT after a

VSE ‘// PAUSE’ statement.

PARM=’ACL=aclname[,COUNT=nnnnn]’

The parameters are positional – ACL= must preceed COUNT=

aclname designates the ACL to use for initialization. It must be same as the ACLNAME

parameter used in defining the ACL’s cuu’s in the EPIC Resource Dataset (ERD).

count designates the number of volumes to initialize. It is only used in sequential

initializations and is ignored if present for random initializations. A maximum of 99,999

volumes can be initialized in a TSIDINIT execution. In deciding on the number of

volumes to initialize in one execution, consider the time involved in robotic

mount/demount activity.

Normally, the operator is asked to specify the tape drives to be used. If specific tape drives

are to be used, operator intervention can be eliminated by using a CUU statement. Up to ten

drives can be specified.

If an ACL is being used, there will not be any operator intervention. After a volume is

initialized, it is unloaded via a RUN command. Once the RUN completes and the robot

begins moving to do the “return to slot” action, a mount cannot take place until this return

action has completed. For this reason, it is recommended that two or three, but no more,

CUU’s be used during a TSIDINIT execution.

User must insure that the ACL cuu’s specified in the CUU statements are not in use when

TSIDINIT is submitted for execution.

If in a VM environment, the cuu’s must not be attached to a guest machine other than the one

in which TSIDINIT will execute. If unattached, TSIDINIT will attach the cuu’s when it

begins execution and detach them when finished executing.

The format of the CUU statement is as follows:

CUU=

cuu,cuu,cuu,...

The CUU statement requires the use of UPSI xx1x in your JCL.

VOLSER statements identify which volume serial numbers are written in the VOL1 label.

If random initialization is requested, one VOLSER statement is required for each volume

serial number. If sequential initialization is requested, use only one statement to specify the

starting volume serial number.
