Chapter 20 Upgrading XgOS 379
7. Reboot the server.
This completes the Linux host server upgrade. If you have more servers to upgrade,
complete that task now. If you have upgraded all servers, proceed to “Upgrade OS
on the Oracle Fabric Interconnect” on page 20-373 to upgrade your second Fabric
Director’s operating system.
Upgrading Linux Hosts In a SAN Boot
Environment
When your server boots across the storage network, you upgrade the drivers by
replacing the initrd or initramfs depending on the version of Linux OS running
on the host. The initrd or initramfs is replaced in the /boot partition with the
new initrd containing the updated drivers. Then reboot the server to load the new
drivers. For more information about installing the Xsigo initrd, see the SAN boot
section in the XgOS Remote Booting Guide.
Upgrading VMware Host Servers
Before you begin the XgOS upgrade, migrate all virtual machines from this server to
another. You migrate the VMs in any of the following ways:
■ Drag and drop the VMs through the Virtual Infrastructure Client.
■ Put the ESX server into maintenance mode, and the VMs are automatically
evacuated.
■ Manually migrate multiple virtual machines:
a. Use Virtual Infrastructure Client to connect to VirtualCenter Server.
b. In Inventory View, go to Host & Clusters, Virtual Machines Tab.
c. Highlight each powered up virtual machine that you want to VMotion,
right-click and select “Migrate.”
This will bring up the Migrate Wizard.
d. Follow the Migrate Wizard prompts to complete the VMotion move.
Compatible Software Versions
When upgrading a VMware host server, be aware of the particular versions of ESX
server software and Xsigo host drivers required. Host drivers for each supported
operating system are listed in the release notes.
