The device address must be specified when an emulated device is configured for BS2000.
The names in X2000/M2000 for the channel path identifier and logical unit number (LUN)
are Host Connector and Unit ID, with Unit ID corresponding to the host LUN.
For information on device addresses in BS2000, please also refer to the “System
Installation” manual [
8 ].
When a device is generated for BS2000, the following details are required in addition to the
type-specific data:
●
Unit ID on SU x86 or LUN on SU /390
Possible values:
–
Unit ID: hexadecimal, two digits in the range 00 through FF
– LUN: 0000 through FFFF
All values are functionally equivalent.
●
Mnemonic
Possible values:
–
alphanumeric, two characters (character set: digits and letters)
– hexadecimal, four characters (character set: numbers from 1000 through FFFF)
The mnemonics can be selected in such a way that every customer-specific naming
schema is supported. On an MU no check is made to see whether the specification
matches the mnemonic configured in BS2000. To prevent misunderstandings, they
should be identical.
Every combination of the possible values is permitted.
