Verifying TCP/IP Connectivity

Before you run the nvme connect command on the application server, enter a Linux ping command to check the TCP/IP connectivity between your application server and the Lightbits storage cluster.

Sample Command

$ ping -c 1 10.23.26.8

• rack02-server70: An application server
• 10.23.26.8: The Data NIC’s IP address on one of the Lightbits storage cluster nodes

Sample Output

PING 10.23.26.8 (10.23.26.8) 56(84) bytes of data.

64 bytes from 10.23.26.8: icmp_seq=1 ttl=255 time=0.032 ms

--- 10.23.26.8 ping statistics ---

1 packets transmitted, 1 received, 0% packet loss, time 0ms

rtt min/avg/max/mdev = 0.032/0.032/0.032/0.000 ms

The output indicates this application server has a good connection to the Data NIC IP address on the Lightbits storage server.

It is recommended to repeat this check with all the IP addresses obtained from the lbcli list nodes command.
