HP 3PAR Cluster Extension Software Administrator Guide (5697-1429, March 2012)

NOTE: You must create or copy the array password file on all cluster nodes used by
Cluster Extension. Ensure that the appropriate path is reflected in the configuration
information of each node. During configuration, you will be prompted to confirm if you
want to copy the configuration file on all cluster nodes. If you choose to copy the HP
3PAR Cluster Extension configuration file automatically, the same password file location
is retained on all cluster nodes. If the password file location on each cluster node is
different, ensure that you change the password file location by running the HP 3PAR
Cluster Extension Configuration Tool locally.
b. If you select No, configuration information is saved locally.
You can use the import and export features to copy the HP 3PAR Cluster Extension
configuration file clx3PARcfg from one cluster node to another.
Your configuration information is saved in the clx3PARcfg file in the %HPCLX_3PAR_PATH%\
bin directory.
NOTE: To verify the connectivity between array and cluster nodes, select one or more
configured HP 3PAR storage systems and click Connection Test.

array IP address>PWF=<password file path>}]...]
2. Use the following command to add the available cluster nodes:
clx3PARcofig SERVER /ADD [NAME=servername] [NAME=servername...]
3. Use the procedures in “Importing and exporting configuration information” (page 23) to copy
the configuration information to the other cluster nodes.
