Disabling HA Mode for a LUN or Container

By default, LUNs are online via all available ports. LUNs are considered to be in HA mode when

they are online via both ports in the Array. If necessary, such as for debugging purposes, you can

explicitly take a LUN or a container out of HA mode, so that it is accessible via only one port.

For example, the following command removes the FINANCE LUN from HA mode by setting it

offline for Port B, and making it accessible only from Port A:

When the LUN has been taken out of HA mode, the

show luns command displays the status of

the LUN as

Single and indicates the port from which it is online. For example:

The following command sets a container offline from Port B, making it accessible only from Port A:

(config) # no lun set container Strad201 name FINANCE port B online

# show luns

Container: Strad201

LUN Size RW Bksz Status Ports
