After customer add two new disks  in primary node,  customer didn't run scandisks  in secondary node.So the disk information is  not in VXVM.

Solution

After add two new disks  in primary node, after find device from os layer, need run "vxdctl enable " or  "vxdisk scandisks"  on  both nodes. Switch resource again, no error will occur.
