Installing ESX 4.1 (update 1) on IBM x3690 X5 Servers requires custom drivers.

You can use the driver CD in several ways:

1. To install drivers for devices as part of a new ESX installation
2. To update existing drivers or install new drivers for an existing ESX installation with esxupdate
3. To update existing drivers or install new drivers for an existing ESX or ESXi installation with vihostupdate

(for ESX only)

Note: This procedure has changed since the 3.5 version of driver CD. You will need the ESX installation DVD to begin.

# Place the ESX installation DVD in the DVD drive of the host.

1. Restart the host.
2. Accept the terms of the license agreement.
3. Select a keyboard type.
4. When prompted for Custom Drivers, select Yes to install custom drivers.
5. Click Add to eject the ESX installation DVD.
6. Place the driver CD in the DVD drive of the ESX host.
7. Select driver module to import drivers to the ESX host.
8. Click Next to continue. A dialog box displays the following message: Load the system drivers.
9. Click Yes. After loading the driver module, continue installing ESX. After the drivers are installed you are prompted to swap the driver CD with the ESX installation DVD.

(for ESX only)

1. Power on the ESX host and log into an account with administrator capability.
2. Place the driver CD in the CD-ROM drive of the ESX host.
3. Mount the driver CD.
   1. mkdir /mnt/iso; mount -o loop /tmp/megaraid.iso /mnt/iso
4. Navigate to <cd mount point>/offline-bundle/ and locate the <offline-bundle>.zip file.
5. Run the esxupdate command to install drivers using the offline bundle.

esxupdate --bundle=<offline-bundle>.zip update

[root@esx01 offline-bundle]# esxupdate --bundle=LSI_5.29-offline_bundle-379626.zip update
