3.Issue the removetask –d <TaskID> command to remove the task detail.

4.Rerun the SRM operation again.

If you have multiple failed virtual volumes in the group, you may need to repeat steps 1 through 4 for all volumes.

•For HP 3PAR OS versions up to 3.1.2 MU2:

SRM supports only one-to-one replication. If one of the pair in an SLD setup is selected for an SRM configuration, only the selected pair will be started after re-protect in failover workflow.

Before failback, all the pairs in the SLD setup needs to be started as the requirement for setrcopygroup restore operation. You can run the showrcopy groups <groupname> command to see the status of the SLD groups. All the virtual volume members in the SLD setup has to be in Synced status for failback operation to be successful.

•Primary Array is down or is taken offline:

When the primary array is down or the remote copy link between the primary and secondary array is down, and if you need to run the recovery operation, then perform the follow steps:

1.Click Disaster Recovery with Forced Recovery to execute the recovery.

After completing this step, SRM displays the Recovery Required prompt. This implies that after bringing the storage array or link up, you must run the recovery again.

2.After bringing the storage array or link up, navigate to the Devices tab in SRM and click Refresh to rediscover the devices.

Make sure that the devices are discovered again in SRM.

3.Execute the Recovery and Reprotect operations.

For more information about Disaster Recovery—Forced Recovery option, see the VMware vCenter Site Recovery Manager documentation.

•If the same virtual volume IDs are part of a single RC group across two storage arrays that are part of an SRM array pair, then during failback reprotect operation SRM service might stop. To avoid this issue, maintain unique ids for the virtual volumes in the RC group across the storage arrays.

For Example:

Run the showrcopy command from the HP 3PAR CLI interface. The output for one of the RC Groups is as follows:

showrcopy

As displayed in the above result, the virtual volume id 1741 is same between the primary and secondary volumes in the same RC group. In an RC Group, none of the virtual volumes should have the same virtual volume ID.

System Replication Adapter Software QL227 for VMware specifications

HP System Replication Adapter Software QL227 for VMware is a sophisticated tool designed to enhance data protection and availability for virtualized environments. This software enables seamless replication of virtual machines (VMs) across different locations, ensuring business continuity even in the face of disasters or system failures.

One of the main features of QL227 is its ability to integrate tightly with VMware environments. It supports VMware vSphere, which is a leading virtualization platform, allowing users to leverage their existing infrastructure while benefiting from HP’s data replication technology. The adapter simplifies the process of setting up and managing replication tasks, which can be critical for organizations with stringent uptime requirements.

Another notable characteristic of the HP System Replication Adapter is its support for block-level replication. This technology ensures that only the changed data blocks are transferred to the secondary site, optimizing bandwidth usage and minimizing the impact on system performance. This feature is especially valuable for businesses that operate in environments with limited network capacity.

QL227 also includes advanced monitoring and reporting capabilities. Administrators can easily track the status of replication tasks, with real-time notifications and insights that help ensure data integrity and availability. Additionally, the software offers various recovery options, allowing users to initiate failover or failback processes with minimal disruption to operations.

The adapter’s compatibility with HP’s Enterprise Virtual Array (EVA) storage systems enhances its functionality even further, providing a robust infrastructure for managing replicated data. It is designed to work in conjunction with HP’s other data protection solutions, creating a comprehensive strategy for safeguarding critical business information.

Moreover, HP System Replication Adapter Software QL227 features automated policy management, which simplifies the administration of data replication tasks. This allows organizations to set predefined rules for how, when, and where data should be replicated, reducing the risk of human error and ensuring consistency across environments.

In conclusion, the HP System Replication Adapter Software QL227 for VMware is an essential solution for businesses looking to improve their data replication processes. Its integration with VMware, efficient block-level replication, advanced monitoring capabilities, and compatibility with HP storage systems make it a powerful tool for enhancing data protection and ensuring business continuity. With its innovative features and user-friendly interface, QL227 stands out as a vital component for any organization aiming to secure their virtualized infrastructure.
