My main production environment is in a Dell M1000e blade chassis with M6220 switches in Fabrics B and C. Fabric B is dedicated to vMotion traffic, and Fabric C is dedicated to iSCSi traffic and connected directly to our SAN. None of the switches in either Fabric are connected to the rest of the network, so I am unable to monitor them, and I can only manage the configs through the Dell Chassis Management Controller.
When our consultants set this up two years ago, they configured stacking as follows:
C1=C2
B1=B2
I'd like to change the stacking configuration so it is looped in the following way:
B1=C1=C2=B2
If I make this change and merge the two stacks, will it change the configs on the switches?

This can be done, see the page 15 of the Dell white paper on the subject here: http://www.dell.com/downloads/global/products/pwcnt/en/pwcnt_stacking_switches.pdf
Specifically it says:
Also, in your above proposed cabling you are not completing a loop with your stacking cables. You should always aim to do this, even though it is not a requirement. See page 7 of the Dell m6220 stacking use case: http://i.dell.com/sites/content/business/solutions/whitepapers/zh/Documents/powerconnect-m6220-switch_cn.pdf
