Details

Attribute	Value
Product Name	SQL Server
Event ID	2527
Event Source	MSSQLSERVER
Component	SQLEngine
Symbolic Name	DBCC_INDEX_FILEGROUP_IS_OFFLINE
Message Text	Unable to process index I_NAME of table O_NAME because filegroup F_NAME is offline.

Explanation

This informational message indicates that the index cannot be checked because one of the filegroups that stores data for the index is offline. The state of the files in a filegroup determines the availability of the whole filegroup. For a filegroup to be available, all files within the filegroup must be online. If there are no other problems, all other indexes of the same object will be checked.

User Action

To view the state of the files for the specified filegroup, query either the sys.database_files or sys.master_files catalog view.

Restore the offline file from a backup.
