Managing HP Serviceguard for Linux, Sixth Edition, August 2006

Cluster and Package Maintenance
Using Serviceguard Manager
Chapter 7 239
CAUTION In order to carry out administrative operations, the user of a
Serviceguard Manager client must log into the Object Manager system
as root, using the root password. This effectively grants to the client the
ability to manage all clusters that are serviced by that Object Manager.
If it is not necessary for some users to administer the clusters, you can
have them log in as ordinary users on the Object Manager system. In
this case, they will be able to monitor the clusters but not administer
them.
