Howdy, Just read the drawer statement on : http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c01724621 You are consuming already to much VC-SAN & VC-ethernet modules within the environment. You have 3x6=18 while a maximum of 16 is allowed. What kind of 1/10 VC module do you have have in your 1st primary enclosure? If its a 1/10 with 2x CX4 then you have the wrong modules as primary; you need the 1/10F version (the one with 1xCX4 & 2xXFP 10GB) or the new flex10 module for the 1st primary enclosure that makes up the VCD that every other enclosure act as slave on. I assume your run VC FW 2.10; when possible go to OA FW 2.51 and see the other components that you need to upgrade then on www.hp.com/go/bladesystemupdates. I hope this helps to bring you a little step further? cheers, Jeroen Kleen

Hi Jeroen, Thank you very much for your reply. It greatly helps me to understand the VC technology better. The VC FW is 2.10 and after facing LDAP coonectivity issues in OA, FW were upgraded to 2.51. The challenge faced is the first time implementation of multi enclosure stacking and realizing the dependencies in regards to best practices. Chintan Shah (ASM Sydney)
