ESXi Server
To install and configure boot from SAN on ESXi Server:
1. Log into the iSCSISelect utility pressing when prompted.
2. Use the iSCSISelect utility to log into a target from one adapter and configure it for
boot. For more information, see chapter 9., “Configuring and Managing the iSCSI
Initiator with the iSCSISelect Utility,” on page 1599 and chapter 10., “Configuring
and Managing iSCSI Targets with the iSCSISelect Utility,” on page 1610.
If the iSCSISelect utility is configured properly, a message during boot time
indicates that the iSCSI disk was successfully connected.
3. Install an ESXi Server operating system over the iSCSI LUN. For more information,
refer to the Emulex Driver for VMware User Manual, which is available on the Emulex
website.
Booting from SAN for iSCSI MPIO
MPIO support allows the initiator to log in dual sessions to the same target. In this way
I/O can be sent over either TCP/IP connection to the target. If one session fails another
session can continue processing I/O without interruption to the application. In iSCSI
target configuration, you have the option of setting dual network paths to a single boot
LUN.
Note: Although MPIO boot support allows the initiator to log into multiple sessions,
the iSCSI BIOS currently limits the number of sessions to two iSCSI sessions for
a single boot LUN.
You must follow these steps in this order to configure MPIO boot support for each
operating system.
1. Use the iSCSISelect utility to configure the first path to a boot target.
2. Complete normal operating system installation.
3. Install third-party MPIO software for your operating system.
4. Configure the second path to a single boot LUN through the iSCSISelect utility.
Windows Server
To install and configure MPIO on Windows Server:
1. Log into the iSCSISelect utility by pressing when prompted.
2. Use the iSCSISelect utility to log into a target from one adapter and configure it for
boot by following the steps in “Setting Up a Basic iSCSI Boot Configuration” on
page 1596.
If the iSCSISelect utility is configured properly, a message during boot time
indicates that the iSCSI disk was successfully connected.
Note: Only one instance of the boot LUN must be visible to the server during the
installation. The installation might fail if multiple instances of the boot LUN
are available to the server. Emulex recommends that the Spanning Tree
