Ensure Multipathing is Configured

Get the enclosure name from the following output:


$ vxdmpadm listenclosure
ENCLR_NAME         ENCLR_TYPE     ENCLR_SNO        STATUS    ARRAY_TYPE LUN_COUNT FIRMWARE
==================================================<wbr/>=================================================
purestorage2       PureStorage    1B0C13A9BEB81429 CONNECTED A/A        150       343

Set the IO policy to round-robin for your enclosure:


$ vxdmpadm setattr enclosure purestorage2 iopolicy=round-robin

Verify the setting with the "getattr" command:


$ vxdmpadm getattr enclosure purestorage2
ENCLR_NAME      ATTR_NAME        DEFAULT        CURRENT
==================================================<wbr/>===========
purestorage2    iopolicy         MinimumQ       Round-Robin

You can verify your device information & the number of paths with the following command:


$ vxdmpadm list dmpnode
