In the HA system, the primary and the secondary in the lab was separated. Started the U2000, but it can’t work normally. There was no alarm any more. The database seemed to be good after checking by VCS tool.
After discuss with customers, we decided to initialize the database and then restore the U2000 by the script. Before perform this, need to fix alarmdb. Here is the procedure as below.
1.delete the alarmdb：
#su - sybase
$isql -Usa -Psybase -SDBSVR
>drop database alarmdb
2. delete the device file relating to the database
3. create the database
4. initialize the database by the Msuit
5. restore the info by U2000 script
Log into the system monitor and noticed that fault process wasn’t running. Connected to database and found alarmdb was offline. And there was no free space in the alarmdb log which caused the whole alarmdb can’t be read or written normally.
