I/O Group Count

Type

Select the host type. The following values are possible:

I/O Groups

Select the I/O groups to map the host object to. The I/O groups that are highlighted in the list have a current mapping with the host object. Click the I/O group in the I/O group list. To select multiple I/O groups from the list, press Ctrl while you click on the name of the I/O groups. The list contains all of the I/O groups that can have mappings with the host object.

Connection Type

Select the type of connection that the host uses to attached to the cluster. The following options are available:

Fibre Channel

Select this option if the host attaches to the cluster through fibre channel connections. If you select this options, then specify the following attributes for the fibre channel connection:

Fibre Channel Port Mask: Specify the port login mask for the host. For each login between a host HBA port and node port, the node examines the port mask that is associated with the host object to determines if access is allowed or denied. If access is denied, the node responds to SCSI commands as if the HBA port is unknown. Valid mask values range from 0000 (no ports enabled) to 1111 (all ports enabled). For example, a mask of 0011 enables port 1 and port 2. The default value is 1111 (all ports enabled). You can use a port mask to control the node target ports that a host can access.

iSCSI

Select this option if the host attaches to the cluster through iSCSI connections. If you select this option, then specify the following attributes for the iSCSI connection:

CHAP Authentication Secret: Enter the shared secret that is used to authenticate the SAN Volume Controller cluster to the iSCSI-attached hosts. To remove the current CHAP authentication secret, select Remove CHAP Authentication Secret.
