As I said today on Twitter - this one took up some of my time today.
This bit me in the butt today http://twitpic.com/2hr42l #vCenter Upgrade. Butt - I bite back!!!!— Maish Saidel-Keesing (@maishsk) August 24, 2010
During the upgrade of a vCenter 4.0 Server to 4.1 - which included installing a new 64 bit Windows 2008 R2 Machine and moving the Database from one server to another, I encountered an error during the process of the upgrade of the SQL database which stopped the installation.
The installation log (which is usually located under C:\Users<username>\AppData\Local\Temp<digit>\vminst.log gave me an error
The SQL upgrade log in the same location said:
Error: Failed to execute command: create unique clustered index VPXI_DEVICE_COUNTER_INDEX on dbo.VPXV_DEVICE_COUNTER(entity_id, device_name, stat_id) [24-08-2010 13:50:26] Got exception: ERROR  [Microsoft][SQL Native Client][SQL Server]CREATE INDEX failed because the following SET options have incorrect settings: 'ARITHABORT'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or query notifications and/or xml data type methods.
Which in-turn sent me to Prof. Google and KB 1024449 which in essence says that you will have to make a change to the database server configuration due to some SQL options not being set. Which struck me as strange because this was a default installation - the same as many before.
Which brought me to this thread which suggested an issue with the compatibility mode of the database itself, which was spot on.
A quick change of the compatibility level from 2000 to 2005 and the installation went on without a hitch.
Another successful upgrade completed!!
