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 occurance of events. The WWN shown as ‘Controller ID’ maps

to the WWN of the HBA port associated with the host controller.

To display the attributes of a specified enclosure, including its enclosure type,

enclosure serial number, status, array type, and number of LUNs, use the following
