PernixData FVP 2.0 upgrade to 2.5

pernixdatafvp25upg01

The procedure to perform the PernixData FVP 2.0 upgrade to 2.5 is pretty simple but the installation process requires a specific upgrade order.

FVP 2.5 introduces some new features that expand the application capabilities.

 

Before upgrading

Before upgrading PernixData FVP to new version, keep in mind the following key points:

  • You cannot revert any component back to a previous version of the software.
  • If installation cannot proceed for some reason, uninstall version 2.5 and reinstall the older version.
  • Upgrading the Management Server first allows you to continue working with FVP while you upgrade the host extension module to version 2.5.
  • Hosts running a previous version of FVP continue working if the Management Server has been upgraded to version 2.5 but new features won’t be available until you upgrade host extension as well.

The upgrade process should follow the following order:

Transition VMs to Write Through mode

Before installing the new version of the host extension, all VMs must be in Write Through mode. This configuration is required only if the Host Extension Module has to be upgraded to version 2.5 while upgrading the Management Server can be performed at any time.

To modify the VMs’ Write Policy, access PernixData FVP panel and go to Manage tab. Click on Datastores/VMs and select the VM with Write Back policy set.

Uninstall previous Host Extension Module

Before upgrading to new version 2.5, previous Host Extension Module version must be uninstalled from the host using the prnxuninstall.sh script.

Enable SSH in your host and login the ESXi using a tool like PuTTY. From the SSH console run the following command:

# cp /opt/pernixdata/bin/prnxuninstall.sh /tmp/ && /tmp/prnxuninstall.sh

pernixdatafvp25upg15

 

Install new Host Extension Module

When the older version has be uninstalled successfully, the upgrade is performed using the esxcli command.

esxcli software vib install -d <zip_filename>

# esxcli software vib install -d /tmp/PernixData-host-extension-vSphere5.5.0_2.5.0.0-35945.zip

pernixdatafvp25upg16

When the upgrade has completed, backup the ESXi configuration settings by running the following command:

# /sbin/auto-backup.sh

pernixdatafvp25upg17

Remove the host from Maintenance Mode and disable the SSH connection.

pernixdatafvp25upg18

Repeat this procedure for each host member of the FVP cluster.

 

Enable the vSphere Client plug-in

While in vSphere Web Client the new FVP version is already enabled, for vSphere Client the plug-in must be enabled instead.

Close/Open the vSphere Client and go to menu Select Plug-ins > Manage Plug-ins.
