Is there any specific instruction for daisy chain environment... Anyone has implemented daisy chain c7000, please share your thoughts on do,s and dont,s....

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 Mon, 29 Jun 2009 08:49:00 GMT https://community.hpe.com/t5/bladesystem-general/c7000-daisy-chain/m-p/652#M33637 Jeroen_Kleen 2009-06-29T08:49:00Z https://community.hpe.com/t5/bladesystem-general/c7000-daisy-chain/m-p/653#M33638 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.
