vxunreloc creates as many subdisks on the specified destination disk as there are subdisks to be unrelocated. The string UNRELOC is placed in the comment field of each subdisk record.
Creating the subdisk is an all-or-nothing operation. If vxunreloc cannot create all the subdisks successfully, none are created, and vxunreloc exits.
vxunreloc moves the data from each subdisk to the corresponding newly created subdisk on the destination disk.
When all subdisk data moves have been completed successfully, vxunreloc sets the comment field to the null string for each subdisk on the destination disk whose comment field is currently set to UNRELOC.
The comment fields of all the subdisks on the destination disk remain marked as UNRELOC until phase 3 completes. If its execution is interrupted, vxunreloc can subsequently re-use subdisks that it created on the destination disk during a previous execution, but it does not use any data that was moved to the destination disk.
If a subdisk data move fails, vxunreloc displays an error message and exits. Determine the problem that caused the move to fail, and fix it before re-executing vxunreloc.
If the system goes down after the new subdisks are created on the destination disk, but before all the data has been moved, re-execute vxunreloc when the system has been rebooted.
