HP P6000 Cluster Extension Software Administrator Guide (5697-0986, June 2011)

HP SMI-S configuration
When using HP SMI-S and P6000 Cluster Extension, note the following requirements:
• To function properly, P6000 Cluster Extension requires at least one instance of HP P6000/EVA
SMI-S running on a management server. You must, therefore, set up at least one management
server with HP SMI-S in each data center.
• In a P6000 Continuous Access environment, both P6000/EVA storage systems should be actively
managed by the same management server during the P6000 Cluster Extension resource configur-
ation procedures. After resources are configured, P6000 Cluster Extension can complete failover
with a management server that is passively/actively managing the array.
• If P6000 Cluster Extension cannot connect to the first management server in the list, it can switch
to any of the configured HP P6000/EVA SMI-S instances on the alternate management servers.
To interface with the local array, P6000 Cluster Extension will try all local management servers
before resorting to the remote management servers. To interface with the remote array, P6000
Cluster Extension will also try the local management servers first, unless the intersite links are down.
When the intersite links are down, P6000 Cluster Extension will immediately try to use the remote
management servers to interface with the remote array.
Configuration file (clxsmiscfg) for Linux
P6000 Cluster Extension for Linux uses the binary configuration file clxsmiscfg on each cluster
node. This file is used to store configuration and access information for each configured management
server. The information contained in clxsmiscfg cannot be edited with a standard text editor.
However, management server entries can be added, modified, and deleted using the clxpmu utility,
which is included with the standard installation of P6000 Cluster Extension. See “clxpmu” on page
96 for more information.
After the file clxsmiscfg has been configured locally on a cluster node, it must be copied to each
node in the cluster. clxsmiscfg is located in the P6000 Cluster Extension bin directory: /opt/
hpclxeva/bin.
Configuration tool (clxevaconfig.exe) for Windows
P6000 Cluster Extension for Windows uses the configuration tool (clxevaconfig.exe) to store
configuration and access information for each configured management server. This tool stores
information in the clxevacfg file. However, because the clxevacfg file cannot be edited with a
standard text editor, management server entries can only be added, modified, and deleted using the
configuration tool that is included with the standard installation of P6000 Cluster Extension. For more
information, see “Configuring P6000 Cluster Extension” on page 25.
SSL protocol
You can configure P6000 Cluster Extension to use the SSL protocol to communicate with the HP SMI-S
server. The SSL setting depends on whether or not SSL has been enabled on the HP SMI-S server side.
Some HP products do not support SSL communication with the HP SMI-S server. Make sure that all of
the products you use with the P6000/EVA storage system that rely on the HP SMI-S server also support
SSL. If you use one product that uses the HP SMI-S server and does not support SSL communication,
you must disable SSL on the HP SMI-S server side and change all clients (for example, P6000 Cluster
Extension) to disable SSL communication.
