VMware Online Data Migration Service Using the iSR6200

Introduction

This document describes the verification steps

required to successfully insert a QLogic iSR6200

Series Intelligent Storage Router in the data path of

a VMware server that is used to perform I/O

operations on LUNs that must be migrated online

to another storage array. It also covers the post

migration steps required to fully utilize the

additional space resulting from data migration to a

larger LUN.

For details on the configuration and zoning

changes required to introduce the router in the data

path, refer to the Data Migration Service for

iSR6200 User’s Guide.

Verifying Original Multi-Pathing Configuration

Follow these steps to verify the original

multi-pathing configuration (see Figure 2-1):

1. In the vSphere Client, click the Configuration

tab.

2. In the left pane under Hardware, click Storage,

and then in the right pane, click Devices.

3. Select the device, and then click Manage

Paths.

4. On the Manage Paths dialog box, verify the

available paths and their status for each device.

3 – Inserting the Router in the Data Path Figure 2-1. Verifying Original Multi-Pathing Configuration 3 Inserting the Router in the Data Path Follow these steps to insert the iSR6200 in the data path: 1. Remove the first direct path from the controller port (for example, Port A) by zoning out the first direct path from the Fibre Channel switch. The path should disappear from the Manage Paths dialog box shown in Figure 2-1. 2.

4 – Presenting Destination LUNs on VMware ESX 3.5 NOTE: Do not remove the virtual machine from the inventory (Step 2) if the virtual machine is the only accessible machine. The following procedure is specific to ESX 3.5. For VMware ESX 4.0, see “Presenting Destination LUNs on VMware ESX 4.0” on page 5. 1. Zone the destination LUN with the VMware host and re-scan the host to show the destination LUN online on the host (see Figure 4-1). Figure 4-1. Zoning the Destination LUN (ESX 3.5) 2.
