Resource disk failure when HP 3PAR Cluster Extension is online
In a cluster resource group, if the Cluster Extension resource is online but dependent disk resource is failing:
•Ensure that the fibre channel connectivity between the servers and the storage systems is up and running.
•Verify that the disk resource is dependent to the Cluster Extension resource.
•Ensure that the Remote Copy volume group managed by the Cluster Extension resource contains the virtual volume which is correctly mapped to the configured disk resource.
•On a cluster node where the Cluster Extension resource is online, ensure that the presented virtual volume is having read/write access on the HP 3PAR storage system.
•Using HP 3PAR Management GUI, verify that the virtual volume is having read/write access on HP 3PAR storage system where Cluster Extension resource is online.
•Rescan disks using Disk Management.
Cluster Extension and HP 3PAR Command Line (CLI) Install/Upgrade
While installing or upgrading HP 3PAR Command Line Interface (CLI), the environment variable Path will be updated with the CLI install directory. Occasionally, this change does not take effect and you may have to
Change of HP 3PAR storage system IP or password file
If there is change in the configured HP 3PAR storage system's IP address in the Cluster Extension configuration or if the configured password file is missing or corrupt, Cluster Extension will fail to communicate with the storage system and cannot perform any Cluster Extension failover operations. You can use the Connection Test option of HP 3PAR Cluster Extension configuration tool to verify connectivity of configured storage systems. To change HP 3PAR storage systems settings, use the Modify option in the HP 3PAR Cluster Extension configuration tool and save the configuration file on all cluster nodes.
Host persona settings
Host personas are a set of behaviors that permit hosts connected to FC ports on the HP 3PAR storage system to deviate from the default host behavior. By assigning a persona to a host, multiple host types that require distinct customized responses can share a HP 3PAR storage system port. For example, hosts running Windows operating systems can all connect to the same HP 3PAR storage system port.
You can set the host persona number when the host is created or modify it later. To display, create, modify, and remove host personas, use the HP 3PAR CLI commands or the HP 3PAR Management Console. For instructions on displaying, creating, modifying, and removing host personas, see the HP 3PAR InForm CLI Administrator’s Manual or the HP 3PAR InForm Management Console Online Help.
NOTE: Host persona setting varies based on the Windows operating system installed on the cluster nodes. For more information, see the HP 3PAR Implementation Guide.
no_fail_wrt_on_err settings
The no_fail_wrt_on_err policy applies only to synchronous Remote Copy.
The no_fail_wrt_on_err group policy (default policy) allows writes to a primary Remote Copy volume group even though the link between the systems in the Remote Copy pair is broken.
