TCP/IP Failsafe - network switch settings
We have an HP Integrity Server with OpenVMS and TCP/IP. We are trying to use the TCP/IP failsafe functionality. We have found that when the primary inteface fails it does not seem to failover, but rather the whole system hangs. Are there any parameters/standards that the network switch must support to allow for the OpenVMS Failsafe to work?
Thanks
Andrew

Re: TCP/IP Failsafe - network switch settings
I might be at least slightly interested in
how you configured this stuff.
For a start:
TCPIP SHOW VERSION
After that, there are probably some other
SHOW things which would reveal some other
vital data.

Re: TCP/IP Failsafe - network switch settings
assuming you've read the TCPIP documentation and configured TCPIP failSAFE IP according to the documentation, it should work.
What did you try to test it ?
Please check the TCPIP messages in OPERATOR.LOG, failSAFE IP displays a lot of useful information via this mechanism.
TCPIP SHOW SERVICE should show the FAILSAFE service to be enabled.
$ IFCONFIG -a should show the relevant interfaces, their addresses and their state.

Re: TCP/IP Failsafe - network switch settings
This sort of error report is common in environments with managed switches. Please have a conversation with your networking staff here as well, as switches can commonly be configured to Not Like hosts that change IP addresses, and can end up with the host locked out, or on the wrong VLAN, or other such details.

Re: TCP/IP Failsafe - network switch settings
Does this mean the console is no longer responding or that the address you've designated fail over is no longer responding?
Are the interfaces configured and the fail over service started? See tcpip$config.com
Review http://h71000.www7.hp.com/openvms/journal/v2/articles/tcpip.html by Matt Muggeridge for configuration tips. Do the interfaces have a dedicated address as well as the fail over address configured? Is the the dedicated address working?
