In AIX platforms or any platforms that uses CPU pools and the CPU get dynamically allocated to the machines. When running splex_uname it shows at that time how many CPUs is actually being use for this NODE, although the physical CPU is higher.
For example lparstat shows 64 cpus and splex_uname shows 8.
$ lparstat -i

Quest Software Inc. splex_uname version 5.1.1.527
Local system info:
Host Name = aix0005
Host ID = IBM,02026CBBD
Operating System = AIX
OS Version = 5.3
Machine Model = IBM,9119-595
CPU Type = PowerPC_POWER5
CPU Speed =
Number of CPUs = 8
The MAX number of CPUs usage for the node that Shareplex is install should be determined. Then license should be cut for maximum number of CPU that can used for the product. License purchased should be the maximum number of CPU that can used for the Shareplex
For Example:
On one server splex_uname showed 8 cpus and the command that we ran confirm this. But the physical CPU was 64:
For example this machine if it always 8 cpu no more is being used then we need to key 8 cpu license should be cut but if in future the number of CPU of this machine increases then you need to get what number of CPU this particular server will be potentially using and get the license for cpu increase.
The other server there splex_uname showed 32 cpu being used although the lparstat -i reported 64 cpu. So you need to get 32 CPU license for this server. If this number of CPU increase to 64 in future then you need to get the 64 cpu license for it. License purchased should be the maximum number of cpu on the server that you need to install shareplex.
