The CPU ID of a NIM client is stored in the NIM database so that the master can perform verification that NIM client commands are coming from the machines that were originally registered as clients. There are two situations when a NIM administrator would not want this CPU ID validation to be performed:
To enable or disable NIM client CPU ID validation from the NIM application:
Manage the client CPU ID validation from the SMIT interface by typing the SMIT fast path:
Client CPU ID validation can be managed on the NIM master by using the validate_cpuid attribute.
To disable client CPU ID validation, set the attribute validate_cpuid=no on the NIM master:
nim -o change -a validate_cpuid=no master
To perform client CPU ID validation, remove the validate_cpuid attribute from the master by setting it to "yes":
nim -o change -a validate_cpuid=yes master
Attention: The value of the validate_cpuid attribute should not be changed while operations are being performed on NIM clients because it could potentially disrupt client communications for active machines.
