HP DataProtector : Cannot obtain Cell Manager host
Came across this one today, the below error suddenly started to appear on a SQL backup that was working one day and stopped the next without any change or modification to the SQL server or Cell Manager:
Normal 0

Cannot obtain Cell Manager host. Check the /etc/opt/omni/client/cell_server file and permissions of /etc/resolv.conf file.
On investigation I found that the CellServer registry key, listed below, was infact empty. Upon re-entering the CellServer (Cell Manager) name the backup started to work again:
HKEY_LOCAL_MACHINE\SOFTWARE\Hewlett-Packard\OpenView\OmniBackII\Site\CellServer
