Hi,
is this a new setup or existing environment was upgraded to 6.0 ?
Did you look at dmp_native_support tunable ? is it set to on ?
refer below
https://sort.symantec.com/public/documents/sfha/6.0/aix/productguides/html/dmp_admin/ch02s01.htm
From above section
Devices that are multi-pathed with Third-party drivers (TPD) |
If a disk is already multi-pathed with a third-party driver (TPD), DMP does not manage the devices unless you remove TPD support. After removing TPD support, turn on the dmp_native_support tunable to migrate the devices. If LVM volume groups are constructed over TPD devices, then perform the steps to migrate the LVM volume groups onto DMP devices. |
To turn on the dmp_native_support tunable, use the following command:
# vxdmpadm settune dmp_native_support=on
The first time this operation is performed, the command reports if a volume group is in use, and does not migrate those devices. To migrate the volume group onto DMP, stop the volume group. Then execute the vxdmpadm settune command again to migrate the volume group onto DMP.
To verify the value of the dmp_native_support tunable, use the following command:
# vxdmpadm gettune dmp_native_support Tunable Current Value Default Value ---------------------------- ---------------- ----------------- dmp_native_support on off
Once tunable is set, scan disk again with vxdctl enable & see if you can see the disk
