42 VMware vSphere Bitfusion on Dell EMC PowerEdge servers | Deployment guide
7.14 Support for backup and restore
Note: To upgrade your cluster, back up the VMware environment, deploy new server virtual machines with
vSphere Bitfusion 2.5 and restore the backup. To upgrade the operating system of a client, install the latest
version of CentOS, Red Hat Enterprise Linux or Ubuntu Server package.
To upgrade the VMware vSphere Bitfusion software from version 2.0 to 2.5, follow the steps:
1. From the Settings tab of the vSphere Bitfusion software, choose Backup/Restore.
Create and download a backup of your vSphere Bitfusion 2.0 cluster
2. Using the vSphere Bitfusion plugin, create and download a backup of your vSphere Bitfusion 2.0
cluster.
3. Open the manifest.json file from the downloaded bitfusionbackup.tar.gz archive file to find
the servers section that has information about the servers in your vSphere Bitfusion cluster at the
time of the backup.
Note: The host ID, hostname, and number of GPUs for each server must be noted.
4. Power off all the vSphere Bitfusion servers in the cluster.
5. Install a new primary vSphere Bitfusion server:
a. Deploy a new primary vSphere Bitfusion server virtual machine using a vSphere Bitfusion 2.5
Appliance OVF Template.
b. During deployment, enter the same hostname as of the primary vSphere Bitfusion 2.0 server.
c. While setting up the new virtual machine, add the same number of GPUs as of the vSphere
Bitfusion 2.0 server.
d. Add a guestinfo.bitfusion.server.host-id configuration parameter. The value of the parameter
should match the host ID of your primary server with vSphere Bitfusion 2.0 server that was listed
in the manifest.json file. For more information, see the Edit Configuration File Parameters
section in the vSphere Virtual Machine Administration document.
e. Power on the server and wait for the vSphere Bitfusion plugin to register itself with the vCenter
server.
6. Restore the backup of the vSphere Bitfusion 2.0 cluster created using the vSphere Bitfusion plugin
and follow the steps to power on the virtual machines:
