This article describes an issue where the vWAF will not start after upgrading from vTM 11.1 to 17.1.
Problem or Goal
If a traffic manager running vTM version 11.1 has upgraded vWAF manually to a version higher than 4.9-41260, the vWAF will refuse to start after upgrading to vTM 17.1.

When rebooting after the upgrade, the error log will show:
SERIOUS appfirewallcontrolerror Error restarting application firewall: stingrayafm stop failed: Usage: service PRODUCT start|stop|restart|status
Error: version for stingrayafm is invalid
SERIOUS appfirewallfailed       All application firewall decider processes have failed
SERIOUS appfirewalldeciderfail  Application firewall decider process running on has failed
SERIOUS appfirewallfailed       All application firewall decider processes have failed

If vTM 11.1 was upgraded to vWAF 4.9-41849, the directory /logs/stingrayafm/stingrayafm-17.1 will show:
[email protected]:/logs/stingrayafm/stingrayafm-17.1# ls -la

To resolve this issue, use one of the following methods:

Method 1: vWAF and WAF updater were both upgraded

  • Download the hotfix attached "Generic-17.1-vWAF_11.1_upgrade.tgz".
  • In the Traffic Manager UI go to  System > Traffic Managers > Upgrade and upload the file.

Method 2: WAF was only upgraded

Copy the directory from the 11.1 folder:
[email protected]:# cd /logs/stingrayafm/stingrayafm-11.1

[email protected]:/logs/stingrayafm/stingrayafm-11.1# ls

[email protected]:/logs/stingrayafm/stingrayafm-11.1# cp -R 4.9-41849
