Troubleshooting installation and maintenance problems
This section helps you locate and identify installation and maintenance problems. The cluster-wide
installation feature allows you to install HP 3PAR Cluster Extension on multiple nodes in a cluster
by running the installer from one node in the cluster. Cluster-wide installation is no different than
local installation on each individual node.
Cluster-wide installation can fail to obtain the remote installation status if a remote node becomes
unreachable. This can happen if the network connection or remote cluster node fails. If this type
of failure occurs, find the error code in the file %WINDIR%\CLXSetup_nodename.result,
available on the unreachable node, and then locate the error in Table 1 (page 16).
In addition to showing the results of the installation process, the .result file helps you identify
the status of remote maintenance if cluster level maintenance (modify, repair, remove) fails.
