Can the CPUID be used to limit TSO logons to a specific LPAR?
Use the SYSID keyword to identify the system to which the authorization applies. The SYSID is actually the SMFID for the LPAR.
TSS ADD(acid) FAC(TSO) SYSID(SYSA)
The above command will allow the user to signon to TSO only on the system with a SYSID of SYSA. If the users tries to signon to TSO on SYSB, the user will not be granted access.
Please see the CA Top Secret Command Functions Guide for more details about the SYSID keyword.
