n
Each Site Recovery Manager Server instance on the protected site and on the shared recovery site
requires its own database.
n
A single shared recovery site can support a maximum of ten protected sites. You can run concurrent
recoveries from multiple sites. See http://kb.vmware.com/kb/2119336 for the number of concurrent
recoveries that you can run with array-based replication and with vSphere Replication.
n
In a large Site Recovery Manager environment, you might experience timeout errors when powering on
virtual machines on a shared recovery site. See “Timeout Errors when Powering on Virtual Machines
on a Shared Recovery Site,” on page 74.
n
When connecting to Site Recovery Manager on the shared recovery site, every customer can see all of
the Site Recovery Manager extensions that are registered with the shared recovery site, including
company names and descriptions. All customers of a shared recovery site can have access to other
customers’ folders and potentially to other information at the shared recovery site. For information
about permissions in a shared recovery site setup, see Managing Permissions in a Shared Recovery Site
Configuration in Site Recovery Manager Administration.
Timeout Errors when Powering on Virtual Machines on a Shared Recovery Site
In a large Site Recovery Manager environment, you might encounter timeout errors when powering on
virtual machines on a shared recovery site.
Problem
When you power on virtual machines on a shared recovery site, you see the error message Error:Operation
timed out:900 seconds.
Cause
This problem can occur if a single vCenter Server instance manages a large number of virtual machines on
the shared recovery site, for example 1000 or more.
Solution
1 Increase the remoteManager.defaultTimeout timeout value on the Site Recovery Manager Server on the
recovery site.
For example, increase the timeout from the default of 300 seconds to 1200 seconds. For information
about how to increase the remoteManager.defaultTimeout setting, see Change Remote Manager Settings
in Site Recovery Manager Administration.
2 Go to C:\Program Files\VMware\VMware vCenter Site Recovery Manager\config on the
Site Recovery Manager Server host machine on the recovery site.
3 Open vmware-dr.xml in a text editor.
4 Set the timeout for reading from the vSphere Web Client.
Set the timeout to 900 seconds (15 minutes) by adding a line to the <vmacore><http> element.
<vmacore>
<http>
<defaultClientReadTimeoutSeconds>900</defaultClientReadTimeoutSeconds>
</http>
</vmacore>
5 Restart the Site Recovery Manager Server service.
