TPVM Upgrade while EFA is Running

The TPVM upgrade activity upgrades the device‘s TPVM image, where a TPVM is installed and running an EFA instance which is managing the device. After the TPVM image is updated, an EFA instance gets reinstalled with the same EFA version as before and rejoined with the active EFA instance.

Assumptions and Limitations

EFA supports SLX-OS 20.3.2a and later. The TPVM upgrade has SLX-OS dependencies for the new SLX tpvm upgrade and tpvm revert commands, and the TPVM configurations being persisted in the SLX running-config.
EFA does not support single-node EFA TPVM deployment.
TPVM can be deployed on multiple high-availability (HA) nodes, but you can upgrade TPVM only on the standby TPVM node.
TPVM upgrade is allowed only on the EFA HA nodes that are managing the devices hosting the EFA HA instances.
The EFA version is reinstalled and remains the same after the TPVM upgrade. An EFA version upgrade must not be performed during the TPVM upgrade. The EFA version upgrade must be done before or after the TPVM upgrade has been performed on both HA nodes as part of the normal EFA upgrade deployment.
Only one device‘s TPVM can be upgraded at a time.
