I have a client that was migrated to SBS 2011 several months ago and most things have been fine. I was asked to look into some performance issues and ran the BPA as usual. BPA reported: "Use psconfig.exe to upgrade one or mor SharePoint databases" Issue:One or more Sharepoint related websites may not be accessible. Bear in mind before this there were no problems with sharepoint reported. I dutifully ran the psconfig as instructed and it failed with the following message:
Failed to upgrade SharePoint Products.
An exception of type System.Data.SqlClient.SqlException was thrown. Additionalexception information: SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x1c80a537; actual: 0x1c832537). It occurred during a read

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.

vent log.
So I found the log file indicated and found the following segment therein (entire log available):
11/09/2012 18:46:49 8 ERR Task upgrade has failed with an unknown exception
11/09/2012 18:46:49 8 ERR Exception: System.Data.SqlClient.SqlException: SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x1c80a537; actual:

I have grown accustom to the requirement to run PSconfig and have had no problems doing so until now. I have no real idea how to proceed from here. Suggestions?
