Verifying connectivity between storage data server (SDS) and storage data client (SDC)

Use this procedure to ping the storage data server (SDS) from storage data client (SDC).

1. Open an SSH session with a VMware ESXi host using PuTTy or a similar SSH client.
2. Log in to the host using root.
3. Type vmkping <ping command> to ping each SDC using the following commands:

   Ping command	Description
   -s	Specifies the packet size, and the number of data bytes sent. (The packet size is 8972 because the IP header is 20 bytes and the ICMP header is 8 bytes.)
   -d	Prohibits fragmentation.
   -I	Specifies the outgoing VMkernel interface.

4. Repeat from each VMware ESXi host using the following commands:

   Ping command	Description
   -s	Specifies the packet size, and the number of data bytes sent. (The packet size is 8972 because the IP header is 20 bytes and the ICMP header is 8 bytes.)
   -d	Prohibits fragmentation.
   -I	Specifies the outgoing VMkernel interface.

   For example:

   NOTE:The following command requires to use vmk number to reference the port group. For a standard build, flex-data3-<vlanid> (if required) is vmk2 and flex-data4-<vlanid> (if required) is vmk3.

   [root@node7:~] vmkping -d -s 8972 -I vmk3 192.168.176.6
   8980 bytes from 192.168.176.6: icmp_seq=0 ttl=64 time=0.191 ms
