You can use the upgrade process to
replace a faulty node in a multi-node TPVM deployment.
Before you begin
- Ensure that the cluster with faulty node is
running EFA 2.5.5 or later.
- Ensure that you have completed the
high-availability prerequisites described in TPVM High-Availability Requirements.
- Ensure that XCO is not deployed on the
replacement node.
About this task
During node replacement process, the faulty node is decommissioned, the replacement node is
provisioned, and the active node is reconfigured to form a cluster.
Perform this procedure on the active node where XCO is installed.
Procedure
-
Enter SLX Linux mode and copy
the XCO tar file to the SLX device.
device# start-shell
scp <username>@<hostip>:<buildpath>/efa-3.4.0.tar.gz
-
Deploy XCO on TPVM from the SLX shell.
device# efa deploy
Starting "efa deploy", DO NOT hit CTRL+C
Step 1: Checking if TPVM is deployed ...
