• If the host uses IPv4 addressing only, type the IPv4 address in the IPv4 Address eld.
6. 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 eld 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.
7. Click OK. A message displays the results of the test.
NOTE: If the physical port is located on a Chelsio iSCSI card, the rst ping test to a specic 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.
8. 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. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Storage tab.
3. In the Storage tab navigation pane, expand Fault Domains → iSCSI, then select the fault domain.
4. In the right pane, click Remove Ports from Fault Domain. The Remove Ports from Fault Domain dialog box appears.
5. Select the check box for each iSCSI port that you want to remove from the fault domain, then click OK.
Delete an iSCSI Fault Domain
Delete an iSCSI fault domain if all ports have been removed and it is no longer needed.
Prerequisites
• The Storage Center iSCSI front-end IO ports must be congured for legacy mode. In virtual port mode, fault domains cannot be
deleted.
• The fault domain must contain no iSCSI ports.
Steps
1. Select a Storage Center from the Storage view. (Data Collector connected Storage Manager Client only)
2. Click the Storage tab.
3. In the Storage tab navigation pane, expand Fault Domains→ iSCSI, then select the fault domain.
4. In the right pane, click Delete. The Delete Fault Domain dialog box appears.
5. Click OK.
Conguring NAT Port Forwarding for iSCSI Fault Domains
Port forwarding allows iSCSI initiators (servers or remote Storage Centers) located on a public network or dierent 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 congured 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 congured in parallel on the Storage Center fault domains to make sure that iSCSI target control port
redirection functions correctly. Fault domains can only be modied by administrators.
NOTE: If Storage Center iSCSI ports are congured for legacy mode, the port forwarding rules do not need to be dened
on the Storage Center because there is no control port redirection.
