"The log for database MYDB is not avaiable" .. when writing an UPDATE statement to a table.
We first observed this problem today in a database but I found out that in addition we have had an error in the application log
"Backup Request: WaitForIOCompletion: Write failure on backup device "Y:\MyDB_Log.ld.
Operating Syste Rror 1117: The request could not be perfoirmed because of an IO error".
I can perfectly see the LUN where the transaction log is and I can get to that folder an d connect to the database to do SELECTS or even see the properties from Enterprise Manager, but we cannot do anything that involves the transaction log.
