  • Walk through the steps as they happen in the build slide. Major points to make: - even though the transaction has committed in the local log, the commit is not acknowledged to the user until notification has been received from the mirror that the transaction is also hardened in the mirror’s log. ‘Hardened’ means the log records are written to the oxide on the mirror’s log drive. It does NOT mean that the log records have been replayed on the mirror database. - the mirror is an *exact* copy of the principal – this is important to understanding why automatic page repair works.

  • If affinity masking is being used, you must update the relevant masks. Affinity masking is where certain CPUs are included/excluded from being used by SQL Server. An affinity I/O mask further narrows down the use of the CPU by SQL Server to only I/O operations, thus preventing multiple CPUs’ caches being polluted with I/O data.If questioned about affinity masks - All zeroes means that Windows decides which CPUs are used - Non-zero: single bit per CPU, if bit is 1, SQL Server will use it - bit cannot be set in affinity AND affinity I/O maskSee http://www.sqlskills.com/blogs/paul/2008/01/10/SQLServer2008HotAddCPUAndAffinityMasks.aspx
