Hi all,
I've been running SQL2008 R2 RTM Enterprise Edition on a test server for a few months (Windows Server 2008 Ent SP2 - 64bit Hyper V), with no problems.
Today I installed SQL2008 R2 SP1 (64 bit), which seemed to install ok.
However after the install the service won't start. In the event log I get the following:
"Script level upgrade for database 'master' failed because upgrade step 'upgrade_ucp_cmdw.sql' encountered error 515, state 2, severity 16. This is a serious error condition which might interfere with regular operation and the database will be taken offline. If the error happened during upgrade of the 'master' database, it will prevent the entire SQL Server instance from starting. Examine the previous errorlog entries for errors, take the appropriate corrective actions and re-start the database so that the script upgrade steps run to completion".
Followed by ..
"Cannot recover the master database. SQL Server is unable to run. Restore master from a full backup, repair it, or rebuild it. For more information about how to rebuild the master database, see SQL Server Books Online"
Of course I could do this but want to know what the problem is before I start installing it to any live servers!!
I've also found that there isn't an option to de-install the SP from Programs & Features which I thought you could with the later SQL versions???
Can anyone shed any light on the above please, I'd be very grateful for any input.
Thank-you

I'm sorry to hear that you had issues in upgrading to SP1. I can't give you a solid reason as to why it might have happened, but there's a reoccurring theme to the 515 error that has to do with renaming the sa account which causes a system procedure creation failure upon installation.
Within the add/remove programs window, you must check the "show updates" box at the top of the window. This will show "Service Pack 1 for SQL Server 2008 R2 (KB2528583)" right under "SQL Server 2008 R2". You will be able to remove it from there.

Doh, what a schoolboy error on my part, yes I had renamed 'sa'! Thanks so much for the info re this and the uninstall notes. Now the repair isn't working but I'll get round that somehow. At least I know what I need to look out for next time. Thanks again!!
