Test Network Connectivity for an iSCSI Port in a Fault Domain
Test connectivity for an iSCSI physical or virtual I/O port by pinging a port or host on the network.
1. Expand the Dell Storage Manager menu, and then click Storage.
2. In the SC Series tab, select a Storage Center to open the Storage Center view.
3. Click the Storage tab, and then click the Fault Domains subtab.
4. Select the fault domain, then click Edit. The Edit iSCSI Fault Domain dialog box opens.
5. In the Ports table, select the physical port for which you want to test connectivity.
6. Type the IP address of the host to which you want to test connectivity.
• If the host uses either IPv4 or IPv6 addressing, type the IP address of the host to which you want to test connectivity in
the IP Address field.
• If the host uses IPv4 addressing only, type the IPv4 address in the IPv4 Address field.
7. From the Ping Size drop-down menu, select a size in bytes for the ping packets, not including overhead. If you select Other,
type a value between 1 and 17000 bytes in the field below the menu.
NOTE: The Ping Size drop-down menu might not appear depending on the hardware I/O cards used by the Storage
Center.
8. Click OK. A message displays the results of the test.
NOTE: If the physical port is located on a Chelsio iSCSI card, the first ping test to a specific IP address fails and
displays the error SendPing: No ARP entry for nn.nn.nn.nn, sending ARP now. Try again later. Run
the ping test again to verify connectivity.
9. Click OK to close the message.

Remove Ports from an iSCSI Fault Domain
Before you repurpose one or more front-end iSCSI ports, remove them from the fault domains to which they belong.
1. Expand the Dell Storage Manager menu, and then click Storage.
2. In the SC Series tab, select a Storage Center to open the Storage Center view.
3. Click the Storage tab, and then click the Fault Domains subtab.
4. Select the fault domain, then click Edit. The Edit iSCSI Fault Domain dialog box opens.
5. In the Ports table, select the iSCSI port to remove from the fault domain.
6. Click Edit Settings. The Edit Port dialog box opens.
7. Clear the Include check box. Then click OK.
Configuring NAT Port Forwarding for iSCSI Fault Domains
Port forwarding allows iSCSI initiators (servers or remote Storage Centers) located on a public network or different private network
to communicate with Storage Center iSCSI ports on a private network behind a router that performs Network Address Translation
(NAT).
For each Storage Center iSCSI control port and physical port, the router performing NAT must be configured to forward
connections destined for a unique public IP address and TCP port pair to the private IP address and TCP port for the iSCSI port.
These port forwarding rules must also be configured in parallel on the Storage Center fault domains to make sure that iSCSI target
control port redirection functions correctly. Fault domains can only be modified by administrators.
NOTE: If Storage Center iSCSI ports are configured for legacy mode, the port forwarding rules do not need to be
defined on the Storage Center because there is no control port redirection.
