Symptoms

When PVC/PSBM/PCS node's update is initiated from PVA Management Panel in "Infrastructure > Node_name > Software updates > Install Everything", the task may end up with:

#312 Connection to the remote host cannot be opened or is closed

failed_task

Cause

PVA Agent update has been selected for installation among the rest of components.

software_list

When installing updates from PVA Management Node, PVA Agent on the node crashes during self-update.

~# service pvaagentd status
pvaagentd dead but pid file exists

This issue is recognized as PVA-34030 and will be permanently fixed in future releases.

Resolution

  • If faced the issue - login to the PVC/PSBM/PCS node that has been updated and restart PVA Agent.

    ~# service pvaagentd restart
    
  • To prevent issue happening on other nodes:

    First, update PVA agent to the latest version manually per instructions from the KB article:

    • 113071 How to install/reinstall/upgrade PVA Agent on PCS 6, PSBM 5, or PVCfL 4.7 HW Node

    Then it is fine to install the rest of updates from PVA Management interface, in "Infrastructure > Node_name > Software updates > Install Everything".

P.S.: usually, despite the fact that the task ends up with the error, all selected updates are installed correctly.
