Error description
When migratelp is run on 2nd or 3rd mirror pools copies of a LV, it returns the following error: # migratelp palv1/1/2 hdisk3 0516-404 allocp: This system cannot fulfill the allocation request. There are not enough free partitions or not enough physical volumes to keep strictness and satisfy allocation requests. The command should be retried with different allocation characteristics. 0516-990 migratelp: Unable to create new allocation for logical volume palv1.
Local fix
Problem summary
For LVs using mirror pools, migratelp will fail with above message if trying to migrate the 2nd or 3rd copy PPs to another disk without explicitly specifying which PPnum to migrate to on the new disk. When PPnum isn't specified, LVM's allocator is used to find a free PP on the specified disk. The allocator has some logic for mirror pool LVs that isn't really valid for migratelp, and causes it to incorrectly fail to find a free PP to migrate to.
Problem conclusion
Avoid this logic in the allocator for migratelp.
Temporary fix
