Initializing Tapes for BIM-EPIC Control

User Reference

Use Pursuant to Company Instructions

12-13

 For non-virtual ACLs, a robot reads the cartridge barcodes. This

requires the volume serial numbers specified to TSIDINIT match

the appropriate barcodes.

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

allow the operator to control initialization from the console. This has the

same effect as entering EXEC TSIDINIT after a VSE // PAUSE’

statement.

PARM=’ACL=aclname[,COUNT=nnnnn]’

ACL= must precede COUNT=

Definitions The following provides definitions for the parameters you can use when

initializing tapes.

CUU Statement Under normal conditions, the operator is prompted to specify which tape

drives to use. Up to ten drives can be specified. However, if specific tape

drives should not be used, a cuu statement can eliminate operator

intervention.

If an ACL is used, operator intervention is not required. After a volume is

initialized, the volume is unloaded via a RUN command. After the RUN

completes, a robot “return to slot” action takes place. During this time,

another mount cannot take place until the return action is finished. It is

recommended that a minimum of two and no more than three drive

addresses (cuu) be used during a TSIDINIT execution.

The operator must verify that the ACL device addresses specified in the

cuu statements are not in use when TSIDINIT executes.

If the action takes place in a VM environment, the device addresses must

not be attached to a guest machine other than the machine in which

TSIDINIT executes. If unattached, TSIDINIT will attach the device

addresses when it begins execution and detach the devices when finished

executing.

Parameter Definition

aclname Designates the ACL to use for initialization. The

aclname must be same as the ACLNAME

parameter used in defining the cuu in the EPIC

Resource Dataset (ERD).

COUNT Designates the number of volumes to initialize. Use

COUNT only in sequential initializations. COUNT is

ignored if present for random initializations. A

maximum of 99,999 volumes can be initialized in a

TSIDINIT execution. When deciding the number of

volumes to initialize in one execution, consider the

time involved in robotic mount/demount activity.
