Administrator Guide

Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
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.
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.
iSCSI NAT Port Forwarding Requirements for Virtual Port Mode
The following requirements must be met to configure NAT port forwarding for an iSCSI fault domain in virtual port mode.
• For each Storage Center iSCSI control port and virtual port, a unique public IP address and TCP port pair must be reserved on the
router that performs NAT.
• The router that performs NAT between the Storage Center and the public network must be configured to forward connections
destined for each public IP address and port pair to the appropriate Storage Center private target iSCSI IP address and private port
(by default, TCP port 3260).
iSCSI NAT Port Forwarding Example Configuration
In this example, a router separates the Storage Center on a private network (192.168.1.0/24) from a server (iSCSI initiator) on the public
network (1.1.1.60). To communicate with Storage Center iSCSI target ports on the private network, the server connects to a public IP
address owned by the router (1.1.1.1) on ports 9000 and 9001. The router forwards these connections to the appropriate private IP
addresses (192.168.1.50 and 192.168.1.51) on TCP port 3260.

Configure NAT Port Forwarding for an iSCSI Fault Domain
Configure NAT port forwarding for a fault domain to make sure that control port redirection works correctly.
Prerequisites
When the router that performs NAT and port forwarding receives inbound iSCSI connections destined for the specified public IP and
public port, it forwards the connections to the private Storage Center iSCSI IP address and private port (by default, TCP port 3260).
