Read the Before You Start information, and then click Next to continue. Select the pools and any individual hosts that you want to upgrade, and then click Next. If you choose Manual Mode , you must run the XenServer installer on each host in turn. Follow the on-screen instructions on the serial console of the host. When the upgrade begins, XenCenter prompts you to insert the XenServer installation media or specify a network boot server for each host that you upgrade. Choose whether you want XenCenter to automatically download and install the minimal set of updates hotfixes after upgrading the servers to a newer version.

The apply updates option is selected by default. However, you must have internet connection to download and install the updates. Follow the recommendations to resolve any upgrade prechecks that have failed. If you would like XenCenter to automatically resolve all failed prechecks, click Resolve All. If you choose Automatic Mode , enter the installation media details. Do not enter the user name and password associated with your XenServer pool. When the upgrade begins, the Rolling Pool Upgrade wizard guides you through any actions you must take to upgrade each host.

Follow the instructions until you have upgraded and updated all hosts in the pools. If the upgrade or the update process fails for any reason, the Rolling Pool Upgrade wizard halts the process. This allows you to fix the issue and resume the upgrade or update process by clicking the Retry button.

Performing a rolling pool upgrade using the xe CLI requires careful planning. Be sure to read the following section with care before you begin. You can only migrate VMs from XenServer hosts running an older version of XenServer to one running the same version or higher.

For example, from version 7. You cannot migrate VMs from an upgraded host to one running an older version of XenServer. Be sure to allow for space on your XenServer hosts accordingly. Citrix strongly advises against running a mixed-mode pool one with multiple versions of XenServer co-existing for longer than necessary, as the pool operates in a degraded state during upgrade.

Key control operations are not available during upgrade. Do not attempt to perform any control operations. Though VMs continue to function as normal, VM actions other than migrate are not available for example, shut down, copy and export. In particular, it is not safe to perform storage-related operations such as adding, removing, or resizing virtual disks.

Always upgrade the master host first. Do not place the host into maintenance mode using XenCenter before performing the upgrade.

If you put the master in maintenance mode, a new master is designated. This allows you to revert a partially complete rolling upgrade back to its original state without losing any VM data.

If you have to revert the rolling upgrade for any reason, you might have to shut down VMs. For details and instructions, see Before you upgrade a single XenServer host. Start with the pool master. Disable the master by using the host-disable command. This prevents any new VMs from starting on the specified host.

Ensure that no VMs are running on the master. Shut down, suspend or migrate VMs to other hosts in the pool. To migrate specified VMs to specified hosts, use the vm-migrate command.

By using the vm-migrate command, you have full control over the distribution of migrated VMs to other hosts in the pool.

To live migrate all VMs to other hosts in the pool, use the host-evacuate command. By using the host-evacuate command, you leave the distribution of migrated VMs to XenServer. You are unable to contact the pool master until the upgrade of the master is complete. Shutting down the pool master causes the other hosts in the pool to enter emergency mode. Hosts can enter emergency mode when they in a pool whose master has disappeared from the network and cannot be contacted after several attempts.

VMs continue to run on hosts in emergency mode, but control operations are not available. Boot the pool master using the XenServer installation media and method of your choice such as, installation CD or network. Follow the XenServer installation procedure until the installer offers you the option to upgrade.

If anything interrupts the upgrade of the pool master or if the upgrade fails for any reason, do not attempt to proceed with the upgrade.

Reboot the pool master and restore to a working version of the master. When your pool master restarts, the other hosts in the pool leave emergency mode and normal service is restored after a few minutes.

On the pool master, start or resume any shutdown or suspended VMs. Migrate any VMs that you want back to the pool master. Ensure that no VMs are running on the host. Salim Hurjuk Salim Hurjuk Aficionado Members posts.
