I am planning on increasing the bandwidth on an existing PortChannel group this coming Weekend.
Although, I have done this on a couple of occasions earlier in prior versions of SANOS, but we are at a newer version of SANOS (3.3.2) now and hopefully it remains same procedure.
I will be using the following steps.
1. Verify the new ports identified for PC are shut (down)on both swicthes.
2. Update these new ports to the following on both the switches:
a. Mode Admin as "E"
b. Speed Admin as "4Gb" (these are MDS directors with SANOS)
c. Rate Mode as "Dedicated"
d. Port VSAN as "1"
3. Add these new ports to the existing PortChannel on both the switches.
4. And bring up (no shut) one port at a time.
Please let me know if I am missing anything to make this a non-disruptive upgrade?
Appreciate your feedbacks at the earliest.
