Rollback the XCO Upgrade

Rollback the XCO upgrade when there is a upgrade failure. After the rollback, XCO operates in the previous state by canceling the upgrade.

About this task

Follow this procedure to rollback the XCO upgrade.

Note

Ensure that the minimum EFA version is 3.1.0 and above and the minimum SLX version is 20.4.2 and above.
Ensure that the minimum available disk space is 2 GB on each SLX TPVM partition. Log in to SLX as a root user and run the following command:
```
[root@SLX-1]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root        16G  4.6G   11G  32% /
```

Procedure

Deploy XCO with rollback.

efa deploy nographics with-rollback slx-peer-ip <ip-address> slx-peer-user <user name> slx-peer-password <password>

When you use the rollback option, the following parameters are required:

slx-peer-ip - SLX IP, which hosts peer TPVM
slx-peer-user - SLX user, which hosts peer TPVM
slx-peer-password - SLX password, which hosts peer TPVM

Example

The following is an example of a deployment with rollback option:

efa deploy nographics with-rollback slx-peer-ip 10.20.54.62 slx-peer-user admin slx-peer-password password

Step 1: Get IP Address assigned to TPVM to deploy EFA  10.20.63.128.
Step 2: Checking for EFA packages in /efaboot directory
1. /efaboot/efa-2.7.2-32.tar.gz
2. /efaboot/efa-2.7.2-31.tar.gz
Enter option: 1
