Displaying extended attributes after upgrading to DMP 6.0
You may see the following changes in functionality when you upgrade to DMP 6.0 from the Storage Foundation 5.1 release:
The device names that are listed in the vxdisk list output do not display the Array Volume IDs (AVIDs).
The vxdisk -e list output does not display extended attributes.
An Active/Passive (A/P) or ALUA array is claimed as Active/Active (A/A).
This behavior may be because the LUNs are controlled by the native multi-pathing driver, MPxIO.
To check whether LUNs are controlled by the native multi-pathing driver
Check the output of the following command. The LUN is controlled by MPxIO if the controller of the affected LUN has the physical name (PNAME) as /scsi_vhci:
# vxdmpadm getctlr all
You can migrate the LUNs from the control of the native multi-pathing driver to DMP control.
To migrate to DMP with Veritas Volume Manager, refer to the section on disabling MPxIO in the Veritas Storage Foundation Administrator's Guide.
To migrate to DMP with OS native volume support, refer to the section on migrating to DMP from MPxIO in the Veritas Dynamic Multi-Pathing Adminstrator's Guide.
