Protection and Recovery of Virtual Machines with Reservations, Affinity Rules,
or Limits
When Site Recovery Manager recovers a virtual machine to the recovery site, it does not preserve any
reservations, affinity rules, or limits that you have placed on the virtual machine. Site Recovery Manager
does not preserve reservations, affinity rules, and limits on the recovery site because the recovery site might
have different resource requirements to the protected site.
You can set reservations, affinity rules, and limits for recovered virtual machines by configuring
reservations and limits on the resource pools on the recovery site and setting up the resource pool mapping
accordingly. Alternatively, you can set reservations, affinity rules, or limits manually on the placeholder
virtual machines on the recovery site.
Protection and Recovery of Virtual Machines with Components on Multiple
Arrays
Array-based replication in Site Recovery Manager depends on the concept of an array pair.
Site Recovery Manager defines groups of datastores that it recovers as units. As a consequence, limitations
apply to how you can store the components of virutal machines that you protect using array-based
replication.
n
Site Recovery Manager does not support storing virtual machine components on multiple arrays on the
protected site that replicate to a single array on the recovery site.
n
Site Recovery Manager does not support storing virtual machine components on multiple arrays on the
protected site that replicate to mulitple arrays on the recovery site, if the virtual machine components
span both arrrays.
If you replicate virtual machine components from multiple arrays to a single array or to a span of arrays on
the recovery site, the VMX configurations of the UUID of the datastores on the protected site do not match
the configurations on the recovery site.
The location of the VMX file of a virtual machine determines which array pair a virtual machine belongs to.
A virtual machine cannot belong to two array pairs, so if it has more than one disk and if one of those disks
is in an array that is not part of the array pair to which the virtual machine belongs, Site Recovery Manager
cannot protect the whole virtual machine. Site Recovery Manager handles the disk that is not on the same
array pair as the virtual machine as an unreplicated device.
As a consequence, store all the virtual disks, swap files, RDM devices, and the working directory for the
virtual machine on LUNs in the same array so that Site Recovery Manager can protect all the components of
the virtual machine.
