ServiceGuard Manager Version A.03.00 Release Notes, Third Edition
Installing and Running ServiceGuard Manager
Chapter 1 23
issue the cmviewcl command to get information about a remote
cluster. Using ServiceGuard Manager, certain users can also relay
the most common administrative commands to ServiceGuard
clusters, and the effect is the same as logging into the node and
issuing the command on the command line.
Please notice, however, that the permissions and access mechanisms
are not the same. The ServiceGuard Manager user’s permissions
depend on his login to the server, not the cluster node. It is the server
that interacts with thecluster nodes on the user’sbehalf,through the
Cluster Object Manager, a ServiceGuard API.
A ServiceGuard Manager user does not need any direct access to the
target nodes that are displayed in the map. The configuration and
status information is collected by his server node and sent back to
the management station.
The server node always accesses other ServiceGuard nodes as
user=root. The server needs access to the nodes. The recommended
access mechanism is to include the server name or IP address in the
target nodes’ cmclnodelist file. A less secure way is to include the
server node in a target node’s .rhosts file. Listing in cmclnodelist
limits contact to ServiceGuard; a listing in .rhosts grants wider
access.
If the user is logged in to the server node as root, the server node will
also display certain common administrative commands in the menu.
The server relays these commands to the clusters in the session for
the users.
If you are updating from an earlier version, think about permissions
on your HP-UX nodes with ServiceGuard Version A.11.13 or later,
with Cluster Object Manager Version A.01.03.01 or later. Any person
who can log in to that node as root may be able to do administrative
commands on anycluster objects on that node’s subnets. If you do not
want access, you can limit the root logins on that node, or limit that
node’s access to particular clusters on its subnets.
