iSCSI host port settings

Use the options in the iSCSI Host Ports panel (Settings > iSCSI > Host Ports) to reset host links and to change the iSCSI IP address, netmask, and gateway for each port on each controller.

The panel includes the following options:

• Reset Host Links. Making a configuration or cabling change on a host might cause the storage system to stop accepting I/O requests from that host. For example, this problem can occur after moving host cables from one HBA to another on the host. To remedy this, you might need to reset controller host links (channels).
• IP Address. IPv4 or IPv6, the port IP address. For corresponding ports in each controller, assign one port to one subnet and the other port to a second subnet. Ensure that each iSCSI host port in the storage system is assigned a different IP address. For example, in a system using IPv4:
  • Controller A port 1: 10.10.10.100
  • Controller A port 2: 10.11.10.120
  • Controller B port 1: 10.10.10.110
  • Controller B port 2: 10.11.10.130
  CAUTION Changing IP address settings can cause data hosts to lose access to the storage system.
• Netmask. For IPv4, enter the subnet mask for the assigned port IP address. The default is 255.255.255.0.
• Gateway. For IPv4, enter the gateway IP address for the assigned port IP address. The default is 0.0.0.0.
• Default Router. For IPv6, enter the default router for the assigned port IP address. If the gateway was set for IPv4 and then ports were switched to IPv6, the default is : : IPv4-address. Otherwise, the default is : : (the short form of all zeroes).
