Modifying port settings: Panel help

Use the Modify Port Settings panel in the SAN Volume Controller Console to change existing cluster Ethernet port settings. If you are changing IP setting that you are currently using to connect to the cluster, you may need to re-establish the connection to the cluster.

Attributes

The following attributes are displayed for IPv4 port settings:

Cluster Ethernet Port: Displays the port number for the Ethernet connection to the cluster. SAN Volume Controller supports two Ethernet ports to provide redundancy.
IP Address: Displays the IP address of the cluster.
Service IP Address: Displays either the static IP address that was defined for the service IP or DHCP, which indicates that the service IP address is dynamically generated by a DHCP server.
Note: If you do not select a service IP address, the SAN Volume Controller selects DHCP to automatically assign a service IP address.
The service IP address is used if the node needs to be started after it has been removed from the cluster.
Subnet Mask: Displays the subnet mask of the cluster. Subnet masks are only valid for IPv4 addresses.
Gateway: Displays the IP address for the default gateway for the cluster.

The following attributes are displayed for IPv6 port settings:

Cluster Ethernet Port

Displays the port number for the Ethernet connection to the cluster. SAN Volume Controller supports two Ethernet ports to provide redundancy.

IP address

Displays the IP address of the cluster. The SAN Volume Controller Console supports the following IPv6 formats:

Eight colon-separated groups of four hexadecimal digits; for example, 1234:1234:abcd:0123:0000:0000:7689:6576
Eight colon-separated groups of hexadecimal digits with leading zeros omitted; for example, 1234:1234:abcd:123:0:0:7689:6576
Zero suppression format; for example, 1234:1234:abcd:123::7689:6576
Note: You can only suppress one set of zeros in an address.

Service IP Address

Displays either the static IP address that was defined for the service IP or DHCP, which indicates that the service IP address is dynamically generated by a DHCP server. The service IP address is used if the node needs to be started after it has been removed from the cluster.

Note: If you do not select a service IP address, the SAN Volume Controller selects DHCP to automatically assign a service IP address.

Zero suppression format; for example, 1234:1234:abcd:123::7689:6576
Note: You can only suppress one set of zeros in an address.

IPv6 Network Prefix

Displays the network prefix that is associated with the IPv6 cluster and service IP addresses. Valid values are 0 - 127.

Gateway

Displays the IP address for the default gateway for the cluster.

Fields

The following fields can be updated for IPv4 port settings:

IP address

Enter a valid IPv4 address for the selected cluster Ethernet port.

Service IP Address

Select the service IP address which connects to a node if the node has been removed from the cluster and is being serviced. You can select one of the following options:

Assign automatically (DHCP): Select this if you want the service IP address to be assigned automatically through a DHCP server.
Static IP:: Enter an IP address for the service IP address.

Subnet Mask

Enter the subnet mask for the cluster.

Gateway

Enter the gateway IP address used for the cluster.

The following fields can be updated for IPv6 port settings:

IP address

Enter a valid IPv6 address for the selected cluster Ethernet port.
