That IBM issue is specific to 4.1 U1. (that specific release requires a specific SATP) other versions (4.1, 4.1U2,5.0) are certified with the default vmware SATP:VMW_SATP_LSI (vmware HCL for DS3500) so I dont think it is appropriate to my case.
I will look in to the logs and try to elaborate the issue...
Thanks for your reply rajvm256...
