There was an outage -- the drives that held logs were lost, so I had to rebuild the system databases to bring the system up, and then restore all databases. Now I need to restore the master so that I can get all the logins back onto the instance -- but for the life of me, I cannot get the instance into single user AND do the restore of the master db.
I stop the service in config mgr
All other sql server services are disabled, so none of them will intrude
I got to cmd prompt and open up sqlcmd -- manuever to the sqlservr.exe directory, and run this; .\sqlservr.exe –c –m
I get all kinds of output, including the service has started in single user mode....
then I open another cmd prompt and try to start sqlcmd, but of course, it tells me
Login failed for user 'domain\me.'. Reason: Server is in single user mode. Only one administrator can connect at this time..
So then I try this -
Turn service back on, normal mode
open cmd prompt, input my sqlcmd statement to restore the master databsase, and leave it there
RESTORE DATABASE master FROM DISK = '.... master.bak' WITH REPLACE
Turn off service
open cmd prompt and run this to startup in single user mode: .\sqlservr.exe –c –m
starts up fine, so I go back to my RESTORE statement and attempt to run it -- it fails, like this:
1> RESTORE DATABASE master FROM DISK = '....master.bak' WITH REPLACE
Shared Memory Provider: No process is on the other end of the pipe.
Communication link failure
What is the correct sequence to make this happen? I must complete this recovery asap. Any input is greatly appreciated.
