MDS 9124E
I am looking to isl two new MDS-9124E (HP C class blade san switch) into our existing fabrics. Each fabric consists of a core 9216I and two MDS9140 isl'ed back to the 9216. Only problem I see is that our existing fabric San-Os version is 2.1(2b) on all switches. The 9124E was released on March 19th and of course the San-os version is 3.1(2a) which is newer than our existing. I checked with HP and they do not recommend downgrading the san-os version to match our fabric.
Anyone run into an issue similar to this? any recommendations?
Thanks

- Personal recommendation
1. downgrade the new one to 3.1(2), which is EMC supported version.
2. allocate 2 ports in old switch in an unused VLAN.
3. Trunk the 2 ports in old switch to new switch, see if successful.
4. You might wish to try out port channel and/or trunking
5. If things ok, ISL normally.
My experience is 2.x can ISL to 3.1(2).

While the combination of SAN-OS 3.1(2a) and 2.1(2b) should work according to Cisco's tests, EMC has not tested or approved 3.1(2a) SAN-OS. My personal recommendation would be to upgrade the other switches to 3.x SAN-OS before you ISL them. You may also want to check EMC's Support Matrix for our tested supported configurations.
Thank you.
