Displaying information about array ports
Use the Dynamic Multi-Pathing (DMP) commands in this section to display information about array ports. The information displayed for an array port includes the name of its enclosure, its ID, and its worldwide name (WWN) identifier.
Note:
DMP does not report information about array ports for LUNs that are controlled by the native multi-pathing driver. DMP reports pWWN information only if the dmp_monitor_fabric tunable is on, and the event source daemon (esd) is running.
To display the attributes of an array port that is accessible through a path, DMP node or HBA controller, use one of the following commands:
# vxdmpadm getportids path=path_name # vxdmpadm getportids dmpnodename=dmpnode_name # vxdmpadm getportids ctlr=ctlr_name
The following form of the command displays information about all of the array ports within the specified enclosure:
# vxdmpadm getportids enclosure=enclr_name
The following example shows information about the array port that is accessible through DMP node c2t66d0s2:
# vxdmpadm getportids dmpnodename=c2t66d0s2 NAME ENCLR-NAME ARRAY-PORT-ID pWWN ============================================================== c2t66d0s2 HDS9500V0 1A 20:00:00:E0:8B:06:5F:19
