Following my SRM Definitive Guide, today we will cover the configuration of Storage Replication
Adapter (SRA) for the EMC DMX4 storage on SRM 5.0
Components:
VMware
vCenter: 5.0
Site Recovery Manager
(SRM): 5.0
Storage Vendor: EMC
Storage Model: DMX4
Storage Model: DMX4
Replication
Technology: SRDF (Symmetrix Remote Data Facility)
The first
document you should take a look at is the one that comes with SRA, EMC SRDF Storage Replication Adapter.
As much as it gives a good start
it’s does not have all the details you might need, in this case I recommend the
Using EMC SRDF Adapter for VMware vCenter Site RecoveryManager 5.0 , which can be found on Powerlink (if you do not
have an account yet, get a registration, it’s free!!)
The firmware
requirements and software requirements are very well documented, there’s no
reason to repeat it here.
For SRM to works
properly you need a way to manipulate the storage (local and remote). Solution Enabler is the
tool for the job, it discovery and manages the storage arrays on behalf of SRM.
You could just
point your SRM server to another server which already has Solution Enabler
installed and working, but, IMHO, it just adds more complexity and dependency
on your solution, my advice is to install it on the SRM server itself.
Solutions Enabler
manipulates the storage through a small disk (6mb) called GateKeeper, it’s a
kind of control LUN, so if you are installing SRM on a virtual server,
provision a RDM/RAW disk in physical mode. (remember that this disk must be
provided by the storage you have your replicated disks)
During Solutions
Enabler installation, make sure you install SYMAPI Server Daemon, it will
create a service, that works on port 2707 that will allow the remote SRM to
communicate with it’s local storage.
Install Solutions
Enabler on both SRM servers (local/remote)
Next step would
be installing SRA, on both servers, there’s not trick here, just NEXT, NEXT,
NEXT…..
The final piece
would be configuring the SRA, it’s done inside the SRM itself. Click on Array
Managers and then on Add Array Manager.
Give it a
descriptive name and choose the SRA type (in this case EMC SRDF)
On Local SYMAPI
Server, just put the IP of local SRM server, or just type local.
On Remote SYMAPI
Server, just put the IP of the remote SRM server.
Configure the SRA
for the remote SRM server as well, just remember to switch the IP’s
information.
Now you can
Enable the arrays and Scan for your replicated disks.
Good luck
