Good Day All,

I am in the process of migrating our SQL clusters from VMAX to XtremIO.  I've created the XIO devices, added them to the SQL host and completed the steps required to start the sync.  I have successfully gotten a few of the devices to the "SourceSelected" state, however as I wait for the remaining devices to sync, the some of the ones that were already in the "SourceSelected" state end up faulting and I get this message -  c7  harddisk10  harddisk18  HostCopy(cl)  sourceSelected  targetLUfault PPME error(22): Target faulted, must abort migration.  I then have to abort and then start the sync all over again.  How do I deal with this issue?  Is it okay once one of the devices is in a "SourceSelected" state to go ahead and commit that device?  If I do that then some of the cluster devices will be on XIO while some will still be on VMAX until the sync has completed and I am able to commit.  Any advice would be appreciated.  I have not contacted support on this as of yet, figured I'd reach out to the community here for advice first.  Thanks in advance.

In the first query below you can see that "c7" is in SourceSelected state.  The second query was run several hours later just to check on the status of the syncing devices.  As you can see "c7" is now faulted.  I aborted and restarted the sync, then set the throttle to 4 (which is 13%).
