Adding VNX hardware (iscsi board)

Hi guys,

I am adding to a vnx5300 2 iscsi board

I'm following this doc:

http://corpusweb130.corp.emc.com/upd_prod_VNX/UPDFinalPDF/en/Add_blade_1578484.pdf

chapter: configuring new blade..

as soon as I reboot the blade what will happen?

will I loose connectivity to the datastores ?

can I do it in a production environment?

should I do even if the vnx already see the new iscsi ?

this is the check command I've used (as per the document):
