SQL Server and NetApp Filer

  • We have SQL Server currently set up to use a NetApp NAS for our logfile and datafile storage. However, in recent days and weeks we have had numerous failures of equipment within our data center causing our SQL Servers to behave irraticly.

    Such outages result in sql log messages:

    2004-03-03 19:42:32.65 spid1 LogWriter: Operating system error 121(The semaphore timeout period has expired.) encountered.

    2004-03-03 19:42:32.65 spid1 Write error during log flush. Shutting down server

    I realize that these outages are difficult to avoid if hardware fails, but I

    would be interested in learning of other technologies that would more

    gracefully handle the outage (iSCSI?), methodologies to either restart the

    service until the service is restored successfully, or alert me or someone else

    that the service has been terminated. Any ideas, tips or examples of your

    implementation of this technology would be appreciated.

    Thanks...

  • We are experiencing the exact same problem with our SQL Server 2k backing onto a NetApp filer

    Whenever we reboot our SQL Server box (Windows 2003, SQL 2k with SP3a), the databases which are stored on the Netapp box are marked as suspect

    If we re-attach the databases, all is restored, but this is not an acceptable solution for us, we would much prefer an option to do this automatically

    Other than writing scripts to automatically re-attach the databases, are there any other options available, and can SQL Server Agent alert on suspect databases.

    In regards to changing the timeout value for SQL Server, where is this value kept, and how can it be edited?

    Any help would be much appreciated,

    Regards,
