Using the YKSETENV command
When the Remote DKC Control function is being used, if you want to make multiple hosts (OSs) on the same site use Business Continuity Manager and share one command device in a storage system, specify the host IDs. If there is only one host (OS) on the site, or you do not make multiple hosts share one command device, you do not need to specify the host ID.
For the host ID, specify a hexadecimal two-digit number from 00 to 1F that is unique for each OS. In an LPAR environment, specify a different number for each LPAR.
The examples below show how to specify a host ID. If neither (a) nor (b) is specified, 00 is assumed.
The following example sets the host ID to 0F:
START YKSETENV,PARM='YKCMDIF=0F'
Defining a system symbol in the IEASYMxx parmlib member
The following example sets the host ID to 0F:
SYMDEF(&YKCMDIF='0F')
