On coming SUN (02/24/2008), We need to expand a SAN disk that hosts a SQL Server 2005 mirrored database. The setup is also uses windows (windows Server 2003) clustered servers at both sites. SAN and Server team tell me that, clustering does not have to be stopped. Also mirroring will not be affected. I am planning on taking a FULL backup on the Primary site and PAUSE Mirroring. This all will be undertaken at a time of less database activity. Is this information correct ? Do we need to stop clustering as well as mirroring ? - Ajayp -- DBA
