Note: The IBM System Storage DS Storage Manager cannot be installed on the VMware
ESX Server, but rather on a Linux or Windows management workstation; however, it can
be the same management workstation that you used for the browser-based VMware
Management Interface.

22.3.1 Mapping LUNs to a storage partition

In this section, we provide notes about LUN mapping that are specific to VMware ESX
Servers.
When you map your LUNs on VMware ESX Server:
It is suggested that you always map the LUNs using consecutive numbers, starting with
LUN 0, for example, map LUNs to numbers 0; 1; 2; 3; 4; 5; and so on, without skipping any
numbers.
On each partition, you must map a LUN 0.
If your configuration does not require LUN sharing (single or multiple independent VMware
ESX Servers, local virtual cluster), each logical drive must be mapped either directly to a
host, or to a host group with a single host as a member.
LUN sharing across multiple VMware ESX Servers is only supported when you are
configuring VMWare vMotion enabled hosts or Microsoft Cluster nodes. On LUNs that are
mapped to multiple VMware ESX Servers, you must change the access mode to Shared.
You can map the LUNs to a host group for the VMware ESX Servers, so they are available
to all members of the host group. For additional information about Windows Clustering
with VMware ESX Server, see the VMware ESX Server Installation Guide at the following

22.3.2 Steps for verifying the storage configuration for VMware

Complete the following steps to help you verify that your storage setup is fundamentally
correct and that you can see the IBM Midrange Storage Subsystem on your VMware ESX
Server:
1. Boot the server.
2. On initialization of the QLogic BIOS, press Ctrl+Q to enter the Fast!UTIL setup program.
3. Select the first host bus adapter that is displayed in the Fast!UTIL panel.
4. Select Host Adapter Settings, and press Enter.
5. Select Scan Fibre Devices, and press Enter. Figure 22-4 on page 670 shows the
resulting output.
