Hi everyone ,
I have build a new ESXI host , ( it is Cisco UCS blade b200-m5 ) , the ESXI image is 6.5u2 build 8294253
the host was totally ok during the installation , I was rebooting it and it was just mint to come back online again
once I configured the port groups and iSCSI vmk and add an iscsi storage device and simple storage scan and then i was able to see the iscsi luns , until now all ok ,
but what i have noticed , after the above was completed , now any reboot for this host will take really too much time to boot
and from KVM I'm seeing vflash loaded successfully and it just hang here . after few hours then it complete and become normal again
does anyone faced the same issue before ?
the above esxi build is the same ISO i used to deploy our old ESXI's .
the old ones do have the same configuration but they are working fine for years now .
any thoughts please ?
Our issue has been fixed,
mtu mismatch
How to fix it ? can you share for me?
