XP12000

Simba — Thu, 12 Jun 2008 13:04:57 GMT

I have a Business Copy instance with one pvol ldev and one svol ldev on an xp12000.
I want to be able to split this pair and under certain circumstances run pairresync with the -restore option to copy the contents of the svol ldev to the pvol ldev (rather than the normal resync where we copy the pvol to the svol.

I have managed to get this to work successfully and test that it correctly copied the svol to the pvol
However it does not work if we also set up CA replication of the pvol to a different XP12000.

If we suspend the CA replication instance the -restore then works correctly

I would like to know if this is in fact the expected behaviour or whether we should be able to do the -restore on a Business Copy instance while also having the pvol replicated to another xp.

If we are not able to do this please point me to the documentation that discusses this

For reference the HORCM log showing the error is reproduced below
