This output shows that the controller c1 is connected to disks that are not in any recognized DMP category as the enclosure type is OTHER.
The other controllers are connected to disks that are in recognized DMP categories.
All the controllers are in the ENABLED state, which indicates that they are available for I/O operations.
The state DISABLED is used to indicate that controllers are unavailable for I/O operations. The unavailability can be due to a hardware failure or due to I/O operations being disabled on that controller by using the vxdmpadm disable command.
The following forms of the command lists controllers belonging to a specified enclosure or enclosure type:
# vxdmpadm listctlr enclosure=enc0
# vxdmpadm listctlr type=ACME

The vxdmpadm getctlr command displays HBA vendor details and the Controller ID. For iSCSI devices, the Controller ID is the IQN or IEEE-format based name. For FC devices, the Controller ID is the WWN. Because the WWN is obtained from ESD, this field is blank if ESD is not running. ESD is a daemon process used to notify DDL about occurrence of events. The WWN shown as 'Controller ID' maps to the WWN of the HBA port associated with the host controller.
