records is still marked as UNRELOC because the cleanup phase is never
executed.
If the system goes down after the new subdisks are made on the
destination, but before they are moved back, the vxunreloc program can
be executed again after thesystem comesback. As described above, when
a new subdisk is created, the vxunreloc program sets the comment field
of the subdisk as UNRELOC. When the vxunreloc utility is re-executed, it
checks the offset, the len, and the comment fields of the existing
subdisks on the destination disk to determine if it was left on the disk at
a previous execution of the vxunreloc program, which then uses it as it
sees fit.
Do not manually modify the string UNRELOC in the comment field.
If one out of a series of subdisk moves fails, the vxunreloc program
exits. Under this circumstance, you should check the error that caused
the subdisk move to fail and determine if the unrelocation can proceed.
When you re-execute the vxunreloc utility to resume the subdiskmoves,
it uses the subdisks created at a previous run.
The cleanup phase isdone with one transaction.The vxunreloc program
resets the comment field to a NULL string for all the subdisks marked as
UNRELOC that reside on the destination disk. This includes clean up for
those subdisks that were unrelocated in any previous invocation of the
vxunreloc program, that was not successfully completed.
