Verifying network connections

Verifying connectivity

To verify storage system network connectivity, complete the following steps.

Step	Action
1	If you want to verify a...	Then...
	Hostname interface	Complete Steps 2 and 3.
	IP address of an interface	Complete Steps 4 and 5.
2	At a client attached to the network, enter the following command: ping hostname-interface hostname is the host name that you assigned to the storage system when you ran `setup`. interface is one of the interface names that the storage system assigned when you ran `setup`. Example This command tests the network connections for a storage system that has the host name "toaster" with an interface named e0 installed. `ping toaster-e0`
3	Repeat the test once for each interface that is installed in the storage system.
4	At a client attached to the network, enter the following command: ping hostname-IP_address hostname is the host name that you assigned to the storage system when you ran `setup`. IP_address is the IP address that the storage system assigned to that interface during `setup`. Example This command tests the network connections for a storage system that has the host name "toaster" with an interface named e0 installed at 172.25.50.10. `ping 172.25.50.10`
5	Repeat the test once for each interface that is installed in the storage system.

To identify a problem when an interfaces does not respond to a ping command, take the following actions.

Step	Action
1	Check to make sure that the interface is securely attached to the network.
2	Check to make sure that the media type is set up correctly if the interface is using a multiport Ethernet card with different port speeds.
3	Check to make sure that the routers function properly with correct routing information if the `ping` command is issued from a network not directly attached to the interface.
4	If you received a response from the IP address ping but not the hostname ping, there may be a problem with name resolution. See the section Verifying host name resolution.
