SAP starts a few WPs and stops

Question

I moved my 4.6C to another iSeries box on a hosted site with same OS v6r1 by restoring full system backup. Host name, system name are not changed.
IP address is changed. The new server has the same memory size and a lot more dsik space. When I start SAP on the new server It starts
with only 8 or 10 work processes out of 42 wp on the system. The status of th wp that are started is SELW.
I saw error messages in the log file dev_w2 but could not figure out what is causing it. I very much appreciate any clue how to resolve this issue from your past experience or from iterpreting the log listed below.
Thanks All.

Hi Berhanu,
Regarding the number of work processes you might want to check if the entries rdisp/wp_no_* in the instance profile are stil in sync with what you maintained in transaction RZ10. System copy might have set initial values.
