HP 3PAR StoreServ Cluster Extension Software Administrator Guide (5697-2442, July 2013)

PendingTimeout value. Microsoft Cluster provides two properties to adjust state change
recognition or resolution:
• IsAlive
• LookAlive
NOTE: For Windows Server 2008/2008 R2/2012, the IsAlive and LookAlive properties
are replaced by the Thorough Resource Health Check Interval and Basic Resource
Health Check Interval properties.
Bouncing service or application
HP 3PAR StoreServ Cluster Extension will alternate (start and fail) between local nodes if the
ApplicationStartup property has been set to FASTFAILBACK and no remote system is
available until the service or application restart limit has been reached.
Creating array password file
HP 3PAR StoreServ Cluster Extension uses HP 3PAR CLI commands to manage the HP 3PAR
StoreServ Storage objects. HP 3PAR CLI can be installed on the client machine to manage the HP
3PAR StoreServ Storage remotely. Each CLI session requires a user name and an encrypted
password for successful command execution. Alternatively, a onetime password file can be
generated for subsequent use. Generated password file is specific to the HP 3PAR StoreServ
Storage. However, it can be copied to other systems for use. HP 3PAR StoreServ Cluster extension
requires this password file for its operations. For each array managed by HP 3PAR StoreServ
Cluster Extension, appropriate password files must be generated and configured during the HP
3PAR StoreServ Cluster Extension configuration.
After you log into the HP 3PAR command shell (using the valid username and password credentials),
use following command to generate the password file:
setpassword -u <user name> -saveonly -file <file name>
The generated password file is stored in the directory from where the command shell is launched.
For example, if you use %HP 3PAR CLI PATH% to login to the command shell, the generated
password file location will be <HP 3PAR CLI PATH>\bin.
IMPORTANT: If there is any change in the configured IP address of the array or password file
location and content, Cluster Extension will fail to communicate with the array and will not perform
the required actions. At any point of time, you can launch the HP 3PAR StoreServ Configuration
tool and use the Connection Test option to verify connectivity and array credentials, and take
necessary action.
Administration
Cluster Extension administration includes remote management of resources and monitoring of
system resources and logs.
Remote management of HP 3PAR StoreServ Cluster Extension resources in a cluster
You can use the MMC with Failover Cluster Management to manage clusters and configure HP
3PAR StoreServ Cluster Extension resources. Note the following when configuring HP 3PAR StoreServ
Cluster Extension resources by using the MMC from a remote management station:
• When you use the MMC to remotely configure HP 3PAR StoreServ Cluster Extension resource
properties in a Server Core or Hyper-V Server cluster node, the Failover Cluster Management
GUI on the remote management station displays the standard Microsoft Properties tab instead
of the customized HP 3PAR StoreServ Cluster Extension Parameters tab. For more information
