I have a SQL server cluster 2005. Due to the broken of SAN storage's controller and disks, one of my SharePoint content DB has corrupted and has been causing numerous error to the SharePoint. I have run the command "DBCC CHECKDB WITH NO_INFOMDGS" and the truncated output are as following:
Table error: Object ID 53575229, index ID 1, partition ID 72057594038583296, alloc unit ID 72057594043564032 (type In-row data), page ID (3:21580503) contains an incorrect page ID in its page header. The PageId in the page header = (3:21580511).
CHECKDB found 0 allocation errors and 6 consistency errors in table 'AllDocs' (object ID 53575229).

Too many errors found (201) for object ID 1762105318. To see all error messages rerun the statement using "WITH ALL_ERRORMSGS".
CHECKDB found 0 allocation errors and 307 consistency errors in table 'AuditData' (object ID 1762105318).
CHECKDB found 0 allocation errors and 363 consistency errors in database 'ALCIM_WSS_Content'.
repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (WSS_Content).
Error show in the event log:
SQL Server detected a logical consistency-based I/O error: incorrect pageid (expected 3:21580475; actual 0:0). It occurred during a read of page (3:21580475) in database ID 9 at offset 0x00002929576000 in file 'E:\Microsoft SQL Server\Data\MSSQL.1\MSSQL\DATA\WSS_Content_2.ndf'.
The last DB backup creatred was about a month ago so doing DB resotre will be my last choice. Is it possible I can recover the DB without data loss using "DBCC CHECKDB ('WSS_Content', REPAIR_REBUILD)"? Any alternative method to acheive my goal?
Thank you.
