Dynamic Multi-Pathing (DMP) can display the attributes of the enclosures, including the enclosure type, enclosure serial number, status, array type, number of LUNs, and the firmware version, if available.

To display the attributes of a specified enclosure, use the following DMP command:

# vxdmpadm listenclosure emc0 
ENCLR_NAME ENCLR_TYPE ENCLR_SNO            STATUS    ARRAY_TYPE LUN_COUNT FIRMWARE
==================================================================================
emc0       EMC        000292601383         CONNECTED A/A        30        5875

To display the attrtibutes for all enclosures in a system, use the following DMP command:

# vxdmpadm listenclosure all

ENCLR_NAME      ENCLR_TYPE     ENCLR_SNO     STATUS    ARRAY_TYPE LUN_COUNT FIRMWARE
====================================================================================
Disk            Disk           DISKS         CONNECTED Disk       6         -
emc0            EMC            000292601383  CONNECTED A/A        1         5875
hitachi_usp-vm0 Hitachi_USP-VM 25847         CONNECTED A/A        1         6008
emc_clariion0   EMC_CLARiiON   CK20007040035 CONNECTED CLR-A/PF   2         0324

If an A/P or ALUA array is under the control of MPIO, then DMP claims the devices in A/A mode. The output of the above commands shows the ARRAY_TYPE as A/A. For arrays under MPIO control, DMP does not store A/P-specific attributes or ALUA-specific attributes. These attributes include primary/secondary paths, port serial number, and the array controller ID.
