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
2. Create appropriate-sized target volumes on the recovery (secondary) site
3. Create a user on the DS8000 with the appropriate privileges for the DS8000
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:
v The local DS8000 system at the protected (primary) site has mirroring
v The recovery VMware ESX/ESXi hosts are defined as DS8000 hosts at the
v The recovery VMware ESX/ESXi host ports are FC-zoned (Fibre Channel) with
v The name of each DS8000 storage system is unique on both the protected and
v The storage extent pools that contain the replicated volumes at both sites have
v Remote mirroring is defined for all DS8000-based volumes that you intend to
v Your protected volumes are mapped to the protected VMware ESX hosts.
