Taken following action
Selected service profile> on right pane selected server tab
Then selected recover server in action menu
executed reset CIMC and chekced not worked
then executed reset KVM server
still not worked
This is with only one server rest working fine.

Greetings.

Please setup a continuous ping to the CIMC IP, and then do another CIMC reset.  The CIMC should stop responding for a minute or so.  Looking to make sure we don't have a duplicate IP (which is a pretty common issue with see with KVM issues, after Java version)

Also, maybe try setting the IP manually to another IP from the equipment tab, server, inventory, CIMC

Thanks,

Kirk...

Thanks Kriik. It worked.

I have another issue I installed windows 2012 R2 in UCS B200M4 and the Os is up & is able to ping its IP address i.e self ping.

I am unable to ping from outside . not servers gateway from server. I have checked following

1) Cross checked IP address subnet mask & gateway are correct. Vlan too cross checked

2) disabled firewall services in windows server

3) Profile has two nics cards which s are linked to template and checked selecting default natve.

and checked with vlan number in template. both ways it is not working. From networking end the switch ports are in trunked mode and one blade with esx is working and pinging from outside as well

Greetings.

Please try the following:

• Compare the MAC address for the VNICs in the service profile with the NIC properties in Windows (or run ipconfig /all). Want to confirm the NIC ordering/naming you have in windows matches the VNIC you think it matches in the service profile.
• SSH to your UCSM IP. 
• connect nxos (A|B) a/b depends on which side your vnic/nic is pinned to.
• #show mac address-table | in xxxx         (where xxxx is last 4 of the mac address you are troubleshooting.  Do this on both sides/FIs
• Do you have a disjoint Layer 2 configuration (i.e. your network uplinks go to different switches, or same switch with different vlan configurations)?
• If you don't have disjoint layer 2, and we are learning the mac addresses on the right vlans, then there may be an issue on network devices above the FIs.
