What to do next
You can now install SRAs at each site. See “Install the Storage Replication Adapters,” on page 23.
Install the Storage Replication Adapters
A Storage Replication Adapter (SRA) is a program provided by an array vendor that enables SRM to work
with a specific kind of array. You must install an appropriate SRM on the SRM server hosts at the protected
and recovery sites.
Prerequisites
n
SRM server installation creates a directory in which you can install the SRAs. Install the SRM server before
you install the SRAs.
n
Your SRA might require the installation of other vendor-provided components. Some of these components
might need to be installed on the SRM server host; others might require only network access by the SRM
server.
n
SRM might occasionally need to rescan storage arrays. You can improve array rescan times by changing
default value of the Scsi.RescanAllHbas on ESX hosts. If rescan times on ESX hosts are longer than
10 minutes, you may want to set the value of this option to 1.
n
Masking and zoning must be configured for replicated devices to remote ESX hosts for failover. VMware
recommends that you configure storage to create clones or snapshots of the replicated devices. Snapshots
or clones must be masked to the recovery site ESX hosts.
Procedure
1 Download the SRA.
You can download storage replication adapters and their documentation from
http://www.vmware.com/download/srm/. Storage replication adapters downloaded from other sites are
not supported by VMware.
2 Install the SRA on each SRM server host.
Storage replication adapters come with their own installation instructions. The adapter you are using must
be installed on the SRM server host at the protected and recovery sites. You cannot use different adapters,
or different versions of the same adapter, at these sites. Both members of an SRM site pair must use identical
adapters.
3 Re-start the SRM service.
The SRM service looks for SRAs when it starts up. If you add or change SRAs on a host, you must re-start
the SRM server process on that host.
Update the SRM Server
When you update the Site Recovery Manager server, information about vCenter server connections,
certificates, and database configuration is read from the existing installation and reused by the updated
installation.
The update mode of the SRM installer provides a quick way to update the SRM server to a new release without
changing any of the information that you provided for the current installation. If you need to change any of
that information, including database connections, authentication method, certificate location, or administrator
credentials, you must follow the update with a repair mode installation, or uninstall the existing release and
then install the new release.
