Hi Marcelo,

restore_symboltable is a temp file created by NetApp during the recovery and 
it should be deleted after the recover has completed.

I guess the problem is on the netapp box. It is possible that OnTap failed for 
some reason. Maybe some incompatibility issue between the source and target 
versions of Ontap? NW 7.2 is rather old.

What is the size of the restore_symboltable file?
Have you found any erros on the NetApp logs?
