Displaying information about controllers

The following command lists attributes of all HBA controllers on the system:

# 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.

This form of the command lists controllers belonging to a specified enclosure and enclosure type:

# vxdmpadm listctlr enclosure=enc0 type=ACME

CTLR-NAME ENCLR-TYPE STATE ENCLR-NAME
