Starting the Cluster After a System Failure

Learn how to start the server after a system failure.

If the cluster fails because of a system failure and you have enabled the automatic cluster takeover configuration parameter, follow step 1. If you have not enabled the automatic cluster takeover configuration parameter follow step 2.

sSet the automatic cluster takover parameter to the default, which is 1. The instance attempting to connect to the cluster restarts the cluster, acting as the cluster coordinator and recovering the databases. See the Configuring the Cluster for Automatic Cluster Takeover topic for information about configuring the cluster to automatically restart.
If you have not enabled automatic cluster takeover, you must restart the cluster with the dataserver . . . --cluster-takeover parameter. For example, this example adds the -cluster-takeover parameter to the runserver file that originally started the cluster:
```
$SYBASE/ASE-15_0/bin/dataserver \
--quorum-dev=/dev/raw/raw11\
--instance=ase1\
--cluster-takeover
```
Once the cluster is running, restart all the instances normally.
