•Additional protection to the data on the recovery Storage System. HP 3PAR SRA will take a snapshot of the devices on the recovery storage system of the SRM before failover for optional restore purpose. The snapshot name will have the following prefix:

SRM_TARGETBK_RO_<VVID>.

•Support of Dynamic Access Group. The concept of Dynamic Access Group support is to expose LUNs only to the specified HBA initiators provided by SRM. Any exposure of the participating LUNs made to other initiators not on the requested list will be removed. This feature is always enabled.

•Multiple Remote Copy groups in one protected group is not recommended. HP 3PAR SRA will log a warning to user if multiple instances of such configurations are detected during the Test or Recovery operation since this might be an indication that VMs are using virtual volumes from different Remote Copy groups.

•The re-protect operation requires at least one Remote Copy link to be running for the intended storage pair to be up. If a recovery operation is performed as part of the failback process when all Remote Copy links are down, additional manual steps are required on the storage system before the user can re-protect the data.

1.On the original protected storage system, run the command showrcopy groups <RC group name>

If the group role is not Primary-Rev, continue with SRM Reprotect; otherwise, go to step 2.

2.Run the following command to change Remote Copy role:

setrcopygroup reverse –local –current <RC group name>

3.Continue with the SRM reprotect operation.

NOTE: You need not perform these manual steps if the Primary Array is up and if you have validated the HP 3PAR StoreServ SSL certificate for both the Primary and Secondary HP 3PAR StoreServ Storage systems on both the primary and recovery sites. For more information on validating SSL certificates, see “Validating HP 3PAR StoreServ Storage SSL certificates” (page 21).

•If a failover operation is unsuccessful, make sure to clean up the local disaster state cache. Otherwise, the subsequent SRM operations will fail.

On both the protected and recovery sites where HP 3PAR SRA is installed, issue the following command:

◦

◦

TPDSrm viewstate

TPDSrm cleanstate -sysid <StorageSystemID> -rcgroup <RCGroupName>

•If HP 3PAR SRA fails the QuerySyncStatus call due to the GetTaskStatus call returning the error, Malformed InServ Data List: xxx, perform the following steps to work around this problem:

1.Get the task ID from the Malformed InServ Data List: {0 {<TaskID>} xxx} error.

2.Log into the HP 3PAR storage system at the protected site and issue the showtask –d <TaskID> command. Ensure that the task ID is valid.

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.
