Nexus 9K Non-disruptive ISSU Not Supported

[dtran]

Hi all, hope everyone is doing well !!!

I just bought a pair of N9504 with dual SUP to replace my N7K. I am working on bringing the N9504s online as we speak and just to find out that non-disruptive ISSU is not supported on N9K modular chassis. I am so disappointed that Cisco took away this feature from the N9K modular chassis. I omit to do my research on this before making the purchase since I have used ISSU a few time on my N7Ks so I would assume it would be available in the N9K. What a bummer .. I love this feature. Anyone has any info on why Cisco choose to NOT support non-disruptive ISSU on N9K modular chassis ?

Thanks in advance !!!

as per below that may be true if i read correctly - is this your situation ?

The ISSU feature is not supported on any Nexus 9504, 9508, or 9516 chassis with N9K-C95xx-FM-Ex or N9K-C950x-FM-R fabric modules inserted in the chassis. Software upgrades with this hardware combination will be disruptive and will require the switch to reload.
