ServiceGuard Manager Version A.02.01 Release Notes
Compatibility Information and Installation Requirements
Chapter 114
• Which operators will use the interface, and on which computers?
To view a cluster, the ServiceGuard Manager operator needs a logon
and password on at least one server on the cluster’s subnets. The
server is a node with ServiceGuard A.11.12 or later.
To administer clusters on the map, these three things must be true:
— The user is logged in to the server node as root
— The server must be an HP-UX node, and must have
ServiceGuard, Version A.11.13 or later installed, with patches.
Administration commands can be relayed TO any discovered
HP-UX or Linux cluster, but only FROM an HP-UX cluster.
— The server node has Cluster Object Manager, Version A.01.03.01
or later.
• Security Considerations
If you are an experienced ServiceGuard user, you may notice that the
way a ServiceGuard Manager user gets information about remote
clusters is similar to the way a ServiceGuard command-line user can
issue the cmviewcl command to get information about a remote
cluster. Please notice, however, that the permissions and access
mechanisms are not the same for the two methods.
Both HP-UX and Linux clusters can receive administrative
commands from servers.
However, only HP-UX servers can send administrative commands.
To send administrative commands to a Linux cluster from
ServiceGuard Manager, you must log on to a qualified HP-UX server
node as root.
If you are updating from an earlier version, consider the HP-UX
nodes with ServiceGuard Version A.11.13 (patched) that have
Cluster Object Manager patched to show version A.01.03.01. If a
person can log in as root on that server node, they will be able to do
administrative commands on any cluster objects that ServiceGuard
Manager discovers - that is, any cluster objects on the map.
Installing Software
You can install ServiceGuard Manager on three platforms: HP-UX,
Linux, or Windows. The methods are slightly different for each. Use the
section below that is appropriate for your type of installation.
