Sorry for not responding earlier. Been rather busy.
Just to clear a few things up. This machine does not
have the TSM server code on it. It just has the 4.1.2
client code. The machine has 4 CPU's. Before starting
an incremental backup the CPUs are more that 50% idle.
When a TSM incremental starts up the CPUs are 0-5% idle.
Some of the hdisks are 100% busy and I/O wait is > 80%.
I'm not the actual admin of the machine, just a TSM resource
who is getting posed the question and am not sure what things
to look at for high CPU utilization issues.
