Run the lshosts command to see which host has the DEFAULT host model or type.
HOST_NAME type model cpuf ncpus maxmem maxswp server RESOURCES
hostA DEFAULT DEFAULT 1 2 256M 710M Yes ()
If Model or Type are displayed as DEFAULT when you use the lshosts command and automatic host model and type detection is enabled, you can leave it as is or change it.
If the host model is DEFAULT, LSF works correctly but the host has a CPU factor of 1, which might not make efficient use of the host model.
If the host type is DEFAULT, there might be binary incompatibility. For example, if one host is Linux and another is AIX, but both hosts are set to type DEFAULT, jobs that are running on the Linux host might be migrated to the AIX host and vice versa, which might cause the job to file.
