i have a strange scenario. one of our DBA's asled me to restore a Db from our prod data to another instanct of SQL. i will call that sql1
i chose the date requested 5/17/12 at 6pm.
i restored to sql1, changed the name of the db instance to prod_51712_600pm and saved the mdf and ldf to c:\temp\proddata
i get the following error: Execution of SQL command failed for SQL Server 2008 database prod(mirrored between - PRODSQL and DRSQL1) on SQL Server (MSSQLSERVER).ProdSqlCluster with reason : SQL Server detected a logical consistency-based I/O error: incorrect
checksum (expected: 0x3d3d3d3d; actual: 0x0729561d). It occurred during a read of page (1:1017) in database ID 52 at offset 0x000000007f2000 in file 'c:\temp\prddata\prod.mdf'. Additional messages in the SQL Server error log or system event log may provide
more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books
Online.
Processed 0 pages for database 'prod_51412_600pm', file 'prod'on file 1.
. (ID 30173 Details: Internal error code: 0x80990D18)
i changed some of the names so that noone can know our try data names.
the sql instance on our prodsql is mirrored to our drsql in our dr environment
the restore was sent to our sql1 server. prior to this, i restored 10 other prod data insances to sql1 from the same prodsql server. all mirrored instances
what i did to "fix" the data for the most recent date/time, (today; 5/21/12 9:45am;) i stoped protection of the specific instance. then reportected. i did not delete any data.
i would like to know if the data is corrupt or recoverable from the dpm replica/recovery
if you need any further clarification, please ask. thank you
