5 Parameters for YKBTSCAN
This chapter describes the parameters for YKBTSCAN.
Functionality
YKBTSCAN executes local scans by batch.
YKBTSCAN locally scans the volume of the device number or volume serial number that you entered
from SYSIN, and then creates a disk configuration definition file for the detected volume. If the
disk configuration definition file already exists, YKBTSCAN updates the file by adding the newly
obtained volume information to the existing disk configuration definition file.
The following describes how the scanned volume information is added to the existing disk
configuration definition file:
• When both the scanned volume information and the existing disk configuration definition file
contain a volume with the same storage address (SN, CU, and CCA), the scanned volume
information is added, and the existing volume information is deleted.
• When the scanned volume information and the existing disk configuration definition file contain
a volume with the same host address (DEVN) but different storage addresses, the scanned
volume information is added, and the existing volume information is deleted.
• When the scanned volume information and the existing disk configuration definition file contain
a volume with the same volume serial number (VOLSER) but different storage addresses, the
scanned volume information is added, and only the volume serial number in the existing
volume information is deleted.
Format
Specify YKBTSCAN to PGM in an EXEC statement.
// EXEC PGM=YKBTSCAN,PARM='[SPACE(quantity,increment)]’
There are two types of parameters of YKBTSCAN: parameters specified to the PARM operand in
an EXEC statement, and parameters entered from SYSIN.
Parameters to specify to the PARM operand in an EXEC statement
SPACE(quantity,increment)~<numeric character>((1-16777215))
Specify the amount for the primary and secondary allocations in blocks when allocating the disk
configuration definition file. One block is 4,096 bytes.
If you do not specify this parameter, the capacity of the disk configuration definition file is
automatically calculated and allocated as the primary
Parameters entered from SYSIN
Format
PREFIX(prefix)
DAD(device-address-domain-ID)
DEVN(nnnn[:nnnn][,nnnn[:nnnn]]...)
VOLSER('volser'[:'volser'][,'volser'[:'volser']]...)
Parameters
PREFIX(prefix)~ <PREFIX string of 25 or fewer characters>
Specify the prefix in the disk configuration definition file.
