Nimble Data subnet discrepancy between active and standby controller

[CRD]

Hi there

Looking for some advice on how to resolve this. Have picked up at a client that there is a discrepancy between the Data Subnets Network, Netmask and VLAN id between the active and standby controllers.

This is causing controller manual failover and Nimble firmware update to fail with alert saying contact Nimble support...which will be done just thought I should get some advise here as well.

This array is in production and the active controller A has the correct settings

Thanks

Definitely contact Nimble Support!

I wouldn't have thought that to be possible. The subnets are managed at the Group level, which encompasses the array, which encompasses the controllers.

Please reply with whatever Nimble Support finds and the resolution.

Is your physical cabling and config of switch ports verified to be correct for both controllers?

Hi 

Problem was resolved and it was related to switch vlan configuration not being correct. Once corrected swtich side problem was resolved.

Thank you
