Modifying a host

You can modify a host from the Modifying Host panel.

1. Click Work with Hosts > Hosts in the portfolio. The Viewing Hosts panel is displayed.
2. Select the host that you want to modify and select Modify a Host from the task list. Click Go. The Modifying Host panel is displayed.
   You can modify the following attributes for a host:

   • Name
   • Type
   • I/O group
3. Select either Fibre Channel or iSCSI for the connection type.

   If you select Fibre Channel as the connection type, complete the following steps:

   1. In the Fibre Channel Port Mask field, enter a valid 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.

   If you select iSCSI as the connection type, complete the following steps:

   1. In the CHAP Authentication Secret, enter the shared passphrase which is used to authenticate the cluster to the host.
4. Click OK after you have selected the new attributes. If you are modifying a host-to-I/O group mapping that results in the loss of a VDisk-to-host mapping, the Forcing the Deletion of a Host to I/O Group Mappings panel is displayed. Perform one of the following steps:
   • Click Force Remove to remove the host-to-I/O group mapping.
   • Click Cancel to preserve the host-to-I/O group mapping.
