Support for SLD

•HP 3PAR SRA supports synchronous long distance remote copy groups on HP 3PAR OS 3.1.2 MU3 P16 or later MUs, and HP 3PAR OS 3.1.3 or later.

•HP 3PAR SRA can coexist with a synchronous long distance remote copy group on HP 3PAR OS version 3.1.1 to HP 3PAR OS 3.1.2 MU2.

Workarounds for SLD error codes

This section describes workaround for the following SLD error codes:

•Error code 1110: One of the failure reasons might be remote copy replication role of the RC Group <RC group name> in target storeserv system <target name> is not secondary. Please manually issue the HP 3PAR remote copy setrcopygroup CLI command with reverse option to change the role.

To resolve this, do the following:

1.Run the showrcopy groups <RC group name> command on the original protected storage system.

2.If the group role is Primary-Rev, run the setrcopygroup reverse –local–current <RC group name> command to change remote copy role.

•Error code 1112: HP 3PAR SRA is not able to connect to target storeserv system <target name> to execute the failover operation with restore option. HP 3PAR SRA fails to connect to target HP 3PAR storeserv system with the available credentials. Please try the following options

1.Try accepting target HP 3PAR SSL certificate again 2. Verify the connectivity to target HP 3PAR array from SRM host and retry the operation. If above options do not resolve the issue, please manually issue the HP 3PAR remote copy setrcopygroup CLI command with restore option to change the replication roles.

To resolve this, do the following:

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

2.On the recovery storage system, run the showrcopy groups <RC group name> the command.

3.If the group role is Primary-ReVon the protected storage system, and Secondary-Revon the recovery storage system, run the setrcopygroup restore -t <targetname> <RC group name> command on the protected storage system to change the remote copy roles.

Limitations of SLD configuration

In an SLD remote copy environment with three HP 3PAR StoreServ Storage systems (A, B, and C), where A—B is configured in synchronous mode, A—C in asynchronous periodic mode, and B—C is the standby link in asynchronous periodic mode. SRM/SRA is configured between HP 3PAR StoreServ Storage systems A and C.

•Restore replication after failover:

Data can be restored at the original protected site (A) by discarding all changes made at site

(C)after failover. You cannot perform this from the SRM GUI. However, you can run the commands prepareRestoreReplication and restoreReplication in sequence. You can run these commands from the command prompt using the XML input files.

NOTE: If the commands are executed from the command prompt, the SRM GUI might not reflect the latest status.

For SLD Remote Copy groups, after restore replication , only the remote copy group between A—C will be started automatically by SRA. Once Restore Replication is complete, you must

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.
