Once the problems with the disabled cluster member have been resolved, use the following commands

to allow the member to rejoin the cluster:

# chkconfig --level 2345 rgmanager o n

# chkconfig --level 2345 gfs on

# chkconfig --level 2345 clvmd on

# chkconfig --level 2345 fenced on

# chkconfig --level 2345 lock_gulmd on

# chkconfig --level 2345 cman on

# chkconfig --level 2345 ccsd on

You can then reboot the member for the changes to take effect or run the following commands in the

order shown to restart cluster software:

1. service ccsd start

2. service cman start (or service lock_gulm d start for GULM clusters)

3. service fenced start (DLM clusters only)

4. service clvmd start, if CLVM has been used to create clustered volumes

5. service gfs start, if you are using Red Hat GFS

6. service rgm anager start, if the cluster is running high-availability services (rgm anager)
