Displaying information about controllers
The following command lists attributes of all HBA controllers on the system:
# vxdmpadm listctlr all
# vxdmpadm listctlr all
CTLR-NAME ENCLR-TYPE STATE ENCLR-NAME
===============================================================
c1 OTHER ENABLED other0
c2 X1 ENABLED jbod0
c3 ACME ENABLED enc0
c4 ACME ENABLED enc0
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
or
# vxdmpadm listctlr type=ACME
CTLR-NAME ENCLR-TYPE STATE ENCLR-NAME
===============================================================
c2 ACME ENABLED enc0
c3 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.
