Starting with C/D/H in 1999, I’m coming up on my 10 year anniversary. I’ve had a great time learning many different technologies. I’ve been focused recently on Server 2008, Hyper-V, Citrix XenApp, System Center Configuration Manager and have dabbled some in Novell SecureLogin.

When I’m not working, I enjoy playing softball, running, spending time with my kids, working with our three horses and just puttering around the house.

I was recently pulled in on a project to assist with troubleshooting performance issues on a large number of Citrix servers that had recently gone through the P2V process (physical to virtual).  After the process the servers were running quite slowly. 

We went through various steps to try and troubleshoot the issue, and in reviewing the logs, noticed that there were a lot of Event ID 51 errors that stated, “An error was detected on device \Device\Harddisk0\DR0 during a paging operation”. 

This was only occurring on Windows 2000 servers that had been migrated.

We tried to correct the issue a number of ways including changing the SCSI driver from the default Bus Logic driver to the LSL driver, but the errors continued to appear.  Finally, we removed the page file from the server, and then recreated the page file and the errors went away. 

It was determined that because the OS was Windows 2000, the P2V software did a straight, block-level copy which included the page file, and the page file got corrupted in the copy.
