We currently have two MDS 9513's using code level 3.2(2c) and have several IBM BladeCenter's trunked in with the 9124 Cisco modules. The 9124's are currently at the same code level. How can I determine if we upgrade the 9513's to version 4.1(1c) if the 9124's will still work at the lower code level? I understand that it would be ideal to upgrade all to the same level at the same time but we have to go through another channel to get the BladeCenter 9124's upgraded.
That wont work on MDS director class chassis. The minimum supported version is 3.3(1c) with 4.1.1(c). Please check the release notes below :
