1.5. About Diagnosis
1.5.1. Diagnosis Function
SigmaSystemCenter's diagnosis function enables detailed diagnosis of a failed
environment where the Machine inaccessible error occurred. By setting a policy action
of the diagnosis function, you can set recovery process to be executed only if the
recovery setting is required.
A policy action of the diagnosis function, Diagnose and Power OFF, ends with an error
if the recovery process cannot be executed because the error has an influence on a
whole group or if an error machine is judged normal. If the diagnosis function judges
that there is a possibility for the recovery process to succeed, the function aborts the
managed machine and completes the process. Ensure to set Success to the execution
condition of recovery action after executing the Diagnose and Power OFF action.
Note: The root password must be set for ESX. If not, verification of connection will fail.
The root password can be set from the Virtual Resource tab or the Subsystem Edit
window. The Virtual Resource tab appears by clicking the Environment icon on the
Management view. The Subsystem Edit window appears by clicking the Subsystem
icon on the Management view.
For further information on how to set the root password, see Subsection 2.4.6,
"Configuring the Root Password of a Virtual Machine Server" in SigmaSystemCenter
Configuration Guide.
The diagnosis function can be used only when a managed machine is a virtual machine
server (VMware, XenServer). If the Diagnose and Power OFF action is executed on a
managed machine other than virtual machine servers (VMware, XenServer), Diagnosis
will not be executed but Shutdown or Power OFF will be executed. For the details of
the policy action, see Subsection 1.7.15, "Action for machine / Diagnose and Power
OFF".
The diagnosis function checks the following points:
 If the function can connect to VMware vCenter Server or Pool Master of XenServer
that manages an error machine
 If there are two or more managed machines that raises Faulted as their Hardware
Status in a group to which the error machine belongs
 If the function connects to an (host) OS of managed machines
(The function checks this point on up to five machines in the same group as the
error machine other than the error machine.)
 If a managed machine can access to the shared disk in use
(A managed machine checks this point on up to five machines in the same group
as the error machine other than the error machine.)
