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 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, then expand iSCSI and click the fault domain.
4 In the right pane, click Edit Settings.
The Edit Fault Domain Settings dialog box opens.
5 In the Ports table, click Remove Ports from Fault Domain.
The Remove Ports from Fault Domain dialog box opens.
6 In the Select the ports to remove table, select the iSCSI ports to remove from the fault domain.
7 Click OK to close the Remove Ports from Fault Domain dialog box.
8 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 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.
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.
