I have VxRail cluster version 7.0.100-26719865 and recommended version is 7.0.202-27047874. However once I run update it got corrupted as node 1 never boot up after reboot.
From vCenter view the node 1 was in not responding state.
From the iDrac of the node 1 view all NICs were down.
Once I rolled back to 126.96.36.199 network connections went back online.
The model of SFP’s I am using is Finisar FTLF8536P4BCL
Once I changed SFP to Cisco one, server regain connectivity.
This is obvious incompatibility between Finisar SFP and Mellanox 14.28 NIC driver
Furthermore I have same issue with Dell R740 and R640 with Finisar SFP’s
Case is opened with Dell to investigate!
UPDATE ! New drivers 14.31 works with Finisar!
Stay tuned for update on this matter!
