Node may panic if HAD process is stopped by force and then node is shut down or restarted

Last published : Sep 23, 2026
A node may panic if the HAD process running on it is stopped by force and then it is shut down or restarted.This limitation is observed when you perform the following steps on a cluster node:
  1. Stop the HAD process with the force flag.
    \# hastop -local -force
    or
    \# hastop -all -force
  2. Restart or shut down the node.
The node panics because forcefully stopping VCS on the node leaves all the applications, file systems, CVM, and other process online on that node. If the same node is restarted in this starte, VCS triggers a fencing race to avoid data curruption. However, the restarted node loses the fencing race and panics.
Workaround: No workaround.
