Anleitung Zusammenfassung
replicated volumes between sites by configuring arrays in the SRM. Configuring HP StoreVirtual
Storage arrays in the SRM requires the following:
•
The IP addresses of the HP StoreVirtual Storage managers. More than two addresses can be
input by using a comma or semicolon separator.
•
The same user name and password in each site. This is the administrative user name and
password configured in the CMC.
The user at the recovery site must have full permissions on the management group but can be
limited to read only on all other permissions.
Installing HP StoreVirtual Application Aware Snapshot Manager (optional)
Install and configure the Application Aware Snapshot Manager on both Primary and Remote site
VCenter servers. For installation instructions, see the HP StoreVirtual Storage Application Aware
Snapshot Manager Deployment Guide
The replication schedule controls the application aware snapshot integration. If the schedule has
managed enabled then that enables the application managed snapshot integration, where in SRA
takes managed snapshots in syncOnce and reports to the SRM the recovery points with VM
snapshots using VmImageConsistencyEnabled flag. If the schedule has managed disabled then
that disables the application managed snapshot integration as no managed snapshots are taken.
Exceptions: The SRA can handle any changes in configuration, but this is a normal, baseline
scenario.
How the SRA works with VMware SRM 5.x
The SRA has three primary functions for the SRM:
•
Test Failover—A Test scenario that checks failover conditions and parameters. This will create
temporary writable sources at the Backup Site. In the case of HP StoreVirtual Storage,
SmartClone volumes will be created.
•
Failover—Transitioning production services from a Primary Site to a Backup Site, with the
Primary Site either available or not.
•
Reprotect—After a Failover, planned or unplanned, transitioning production services from the
Backup Site back to the Primary Site. This entails reversing Replication so Replication goes
from Backup to Primary Site, doing a Failover in Reverse, and then reversing Replication again
so replication goes from the Primary to Backup Site.
These functions each depend on specific configuration information in a HP StoreVirtual Storage
management group.
Array and volume discovery
The SRM gets information from the SRA about what volumes are being replicated by the LeftHand
OS software. The SRM then compares that list to the volumes it recognizes in a VMware environment.
For normal SRM operation, a replicated volume needs to have a Remote Copy schedule with
completed remote copies at a different HP StoreVirtual Storage management group under a remote
volume that is not mounted at the remote site. This is a standard HP StoreVirtual Storage Remote
Copy configuration.
For instructions on how to configure Remote Copy schedules, see the HP StoreVirtual Storage
Remote Copy User Guide. The latest version of this document can be found at: http://www.hp.com/
support/StoreVirtualManuals. The same information is available from the HP StoreVirtual Storage
Online Help in the HP StoreVirtual Centralized Management Console.
Volumes recognized by the SRA
Volumes must be configured with scheduled remote snapshots or they will not be considered for
the SRM by the SRA. The SRA recognizes the scheduled remote snapshots as replicated LUNs for
