About this guide ix

xIBM DS8000 Storage Replication Adapter

Chapter 1. Introduction
The IBM DS8000 Storage Replication Adapter (SRA) is a software add-on that
integrates with the VMware vCenter Site Recovery Manager (SRM) solution to run
failovers together with IBM DS8000 storage systems.
The IBM DS8000 SRA extends SRM capabilities to employ DS8000 replication and
mirroring as part of the SRM comprehensive Disaster Recovery Planning (DRP)
solution.
VMware administrators can automate the failover of a DS8000 system at the
protected (primary) SRM site to a DS8000 system at a recovery (secondary) SRM
site. Immediately upon failover, the VMware ESX/ESXi servers at the recovery
SRM site initiate the replicated datastores on the mirrored volumes of the recovery
DS8000 system.
When the protected site is back online, you can run failback from the recovery site
to the protected site by clicking Reprotect in the SRM.
Concept diagram
The IBM DS8000 storage system can use the IBM DS8000 SRA add-on that works
with each instance of VMware vCenter SRM (protected or recovery).
Figure 1 shows how the IBM DS8000 Storage Replication Adapter is integrated in a
typical VMware SRM disaster recovery solution.

System requirements
Your system must have the listed prerequisites before you install the IBM DS8000
SRA.
For complete and up-to-date information about the IBM DS8000 SRA compatibility
and requirements, see the latest release notes.
You can obtain the latest release notes on the IBM Storage Host Software Solutions
information center (http://publib.boulder.ibm.com/infocenter/strhosts/ic).
Prerequisites:
vUninstall any previous versions of the DS8000 SRA. See “Uninstalling the SRA
software” on page 11.
vFeature licenses for DS8000s with FlashCopy®and Metro Mirror/Global Mirror
must be activated at both the protected and recovery sites.
vThe DS8000 storage must run on microcode version 6.3.2 (DS8800) or version 7.0
and later (DS8870).
vThe space-efficient (SE) volumes feature must be enabled on the DS8000, if you
want DS8000 SRA to use SE volumes during test failover operations and backup
in failover operations.
vThe user name and password for both protected and recovery site DS8000
device's Hardware Management Console (HMC) must be the same.
vVMware vSphere Virtual Center Server v5.0 or later with Site Recovery Manager
5.x or later plug-in must be installed.
vEnsure that the system firewall is not blocking the Enterprise Storage Server®
Network Interface (ESSNI) port 1750 and port 1755. Otherwise, SRA fails with
an “Invalid Array ID” message.
vA Fibre Channel (FC) connection must be configured between the VMware ESX
server and the DS8000 storage system.
Note:
1. For information about installing the VMware vCenter Server and Site Recovery
Manager plug-in, refer to the VMware Site Recovery Manager Installation and
Configuration Guide.
2. See the relevant VMware documentation for information about how to install
the compatible versions of vCenter Server, Site Recovery Manager, and vSphere
Client. Also, refer to the latest installation and configuration instructions for
VMware ESX and ESXi servers.

Chapter 2. Preparation
Depending on your specific site configuration, preparation is required as described
in the following topics.
Preparing the DS8000 software environment
Before you install the DS8000 SRA, verify the software implementation.
Procedure
Complete the following steps to prepare the DS8000 storage environment:
1. Verify that the supported storage system microcode version is used. See
“System requirements” on page 2.
2. Create appropriate-sized target volumes on the recovery (secondary) site
DS8000. Create Metro/Global Mirror relationships between the source and
target volumes.
3. Create a user on the DS8000 with the appropriate privileges for the DS8000
SRA. For non-preconfigured settings, a user with “Physical Operator” or higher
privilege is needed. For preconfigured settings, a user with “Copy Services
Operator” or higher privilege is needed.
Note: For information about user privileges, see “Setting user privileges for SRA
configurations” on page 39.
Verify the mirroring configuration
All DS8000 storage systems, volumes, and VMware ESX hosts at both the protected
(primary) and recovery (secondary) sites must be properly connected to their
remote counterparts. The DS8000 systems, volumes, and VMware ESX hosts must
then be configured for site mirroring.
Before you install the IBM DS8000 SRA, verify that the following prerequisites are
completed:
vThe local DS8000 system at the protected (primary) site has mirroring
connectivity with the target DS8000 system at the recovery (secondary) site.
vThe recovery VMware ESX/ESXi hosts are defined as DS8000 hosts at the
recovery site.
vThe recovery VMware ESX/ESXi host ports are FC-zoned (Fibre Channel) with
the DS8000 storage system at the recovery site and are visible by that DS8000
storage system.
vThe name of each DS8000 storage system is unique on both the protected and
recovery sites.
vThe storage extent pools that contain the replicated volumes at both sites have
sufficient free capacity for creating the snapshots of all replicated volumes
concurrently.
vRemote mirroring is defined for all DS8000-based volumes that you intend to
protect as part of your Disaster Recovery Plan.
vYour protected volumes are mapped to the protected VMware ESX hosts.
© Copyright IBM Corp. 2010, 2016 3

Note: Set HostType to VMWare when you configure host connect on DS8000. For
example:
mkhostconnect -wwname 12341234000A000F -hosttype VMWare host_1_port_1
Attention: Confirm with your storage administrator that all the requirements are
met.
Verifying the VMware vCenter SRM installation
Before you install the IBM DS8000 SRA, ensure that the VMware SRM is installed.
The VMware SRM must be accessible at the protected (primary) and recovery
(secondary) sites.
About this task
The following procedure includes steps and screen captures that apply when using
VMware vSphere Client. If you are using VMware vSphere Web Client, similar
steps are applicable, except the step of logging in to vSphere Client.
Procedure
1. Log in to VMware vSphere Client.
2. Go to the home page and confirm that the Site Recovery icon is displayed
under “Solutions and Applications.”

Note: For Metro-Global Mirror storage configuration, SRA does not support
failover to the intermediate site. Install VMware vCenter SRM on the local and
remote sites.
