The following command displays the Dynamic Multi-Pathing (DMP) node that controls a particular physical path:
# vxdmpadm getdmpnode nodename=pathname
The physical path is specified by argument to the nodename attribute, which must be a valid path listed in the device directory.
The device directory is the /dev
directory.
The command displays output similar to the following example output.
# vxdmpadm getdmpnode nodename=sdbc
NAME STATE ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME ==================================================================== emc_clariion0_89 ENABLED EMC_CLARiiON 6 6 0 emc_clariion0
Use the -v
option to display the LUN serial number and the array volume ID.
# vxdmpadm -v getdmpnode nodename=sdbc
NAME STATE ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME SERIAL-NO ARRAY_VOL_ID ===================================================================================== emc_clariion0_89 ENABLED EMC_CLARiiON 6 6 0 emc_clariion0 600601601 893
Use the enclosure attribute with getdmpnode to obtain a list of all DMP nodes for the specified enclosure.
# vxdmpadm getdmpnode enclosure=enc0
NAME STATE ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME ========================================================== sdm ENABLED ACME 2 2 0 enc0 sdn ENABLED ACME 2 2 0 enc0 sdo ENABLED ACME 2 2 0 enc0 sdp ENABLED ACME 2 2 0 enc0
Use the dmpnodename attribute with getdmpnode to display the DMP information for a given DMP node.
# vxdmpadm getdmpnode dmpnodename=emc_clariion0_158
NAME STATE ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME ================================================================== emc_clariion0_158 ENABLED EMC_CLARiiON 1 1 0 emc_clariion0
