The following command lists attributes of all HBA controllers on the system:
# vxdmpadm listctlr all
CTLR-NAME ENCLR-TYPE STATE ENCLR-NAME =============================================================== scsi1 OTHER ENABLED other0 scsi2 X1 ENABLED jbod0 scsi3 ACME ENABLED enc0 scsi4 ACME ENABLED enc0
This output shows that the controller scsi1 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
CTLR-NAME ENCLR-TYPE STATE ENCLR-NAME =============================================================== scsi2 ACME ENABLED enc0 scsi3 ACME ENABLED enc0
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.
