Dell PowerFlex Appliance with PowerFlex 3.x Administration Guide

Verifying connectivity between storage data server (SDS) and PowerFlex gateway

Use this procedure to ping the SDS and PowerFlex gateway from SDS.

1. Open an SSH session with an SDS host using PuTTy or a similar SSH client.
2. Log in to the host using root.
3. Ping each SDS and the PowerFlex using a 9000 byte packet (MTU) without fragmentation on the SDS to SDS data networks.
4. Repeat for each SDS host.
5. Repeat for the PowerFlex gateway.
   In the ping command example below:

   Ping command	Description
   -s	Specifies the packet size and the number of data bytes to be sent. (The packet size is 8972 because the IP header is 20 bytes and the ICMP header is 8 bytes.)
   -M do	Prohibits fragmentation

   For example:

   [root@node4 ~]# ping -s 8972 -M do 192.168.152.102
   8980 bytes from 192.168.152.102: icmp_seq=1 ttl=64 time=0.299 ms
