Hi Ivan
Thanks for your answer!
You have right, the vcenter server version is 5.5.0 update 2 I read wrong the name on my download folder! sorry!
I confirm, the SRA has been installed on the correct path, I check in the compatibility web and they say "Firmware Version 2.4.0.20932" and in my both storage I have the firmware 2.4.3.21886, should be compatible!
I will open a SR on EMC to check this!
thanks again!
