I had faced an interesting issue, during recent upgrade of SCCM. As you must be aware SCCM contains Database updates as well. Fix SCCM SQL DB SUSPECT mode.
Fix SCCM SQL DB SUSPECT Issue :-
During SCCM upgrade the SCCM (ConfigMgr) server (unexpectedly) got restarted. I still don’t know the reason of restart. After that restart I tried re running the R2 update and it got failed. When I checked SQL management studio, the CM_CAS DB is locked and it was in SUSPECT mode. Fix SCCM SQL DB SUSPECT mode.

When I checked SQL management studio, the CM_CAS DB is locked and it was in SUSPECT mode. I never ever seen or heard about this issue 🙁 So what’s next ? Google search hinted me this is common issue for SQL support teams. There are couple of steps to change from Suspect mode to Emergency. Once the DB is in emergency mode we can perform or try some recovery (with Data loss) options.
Following are the SQL commands which I talked about :-
- EXEC sp_resetstatus ‘YOUR_DB_NAME’;
- ALTER DATABASE YOUR_DATABASE_NAME SET EMERGENCY
- DBCC checkdb(‘YOUR_DB_NAME’)
- ALTER DATABASE YOUR_DATABASE_NAME SET SINGLE_USER WITH ROLLBACK IMMEDIATE
- DBCC CheckDB (‘YOUR_DB_NAME’, REPAIR_ALLOW_DATA_LOSS)
- ALTER DATABASE YOUR_DB_NAME SET MULTI_USER
Resolution :- Fix SCCM SQL DB SUSPECT mode
Resolution for this issue was something different. When I first saw the DB is in SUSPECT mode, I did a restart of SQL server and that didn’t make any difference. I did a restart again after 2-3 hours. Woo hooo :)!
The second restart of SQL server helped me. After the second restart the CM_CAS DB came back as single user mode. I changed it to multi user mode using my previous post.
