IP addresses don't disappear after stopping the crsctl script in oracle RAC systems

Solution Unverified - Updated -

Issue

After execution of Oracle RAC script called crsctl, 2 virtual addresses are added to a host at eth3. Ordinary eth3 has only:

  • eth3 10.5.5.131

After script it has

  • eth3:1 10.5.5.143
  • eth3:2 10.5.5.144

That's okay. The issue happens when we run script with "stop" parameter. The aliases are removed from ifconfig -a output, but are still alive and can be used for ping or even for a ssh session.

Environment

  • RHEL5.8
  • Oracle RAC
