Patch to fence_drac from RHEL4U2 branch
Thanks for the patch. This required one minor amendment, and then worked with 4/I firmware 1.20, but now the field reports that it does not work with the latest firmware release (1.30). One other note: This agent will NOT work with the DRAC 4/P, which I think is unfenceable, as it does not have a way to determine power status. I'm running Dell PowerEdge 1955 blade servers in a chassis with DRAC/MC 1.3 firmware, and I'm seeing a similar problem. The fence_drac is able to power off/on the blade, but its not returning the correct status after the power is switched off or on. Example command issued: # fence_drac -a 10.0.0.20 -l username -p password -D debug.txt -m Server-10 -v -o off detected drac version 'DRAC/MC' failed: telnet returned: pattern match timed-out Result: Server is shut off harshly (ie. about 3 services are shutdown in init 6, then power is cut to the machine). Problem: Its great that the server is getting shut down, but fence_node gets thrown into a death loop rebooting the server using fence_drac as the fence program. I fixed the 1.3 problem. It was due to the telnet interface being significantly slower in 1.3 than 1.2, and the 5 second timeout was too short for $telnet_timeout. /sbin/fence_drac, line 33: From: my $telnet_timeout = 5; # Seconds to wait for matching telent response To: my $telnet_timeout = 10; # Seconds to wait for matching telent response 4/I support is added to the agent and the telnet timeout has been increased. In addition, DRAC 4/P support has been added, and has been tested for 4/p firmware version 1.40 An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below.
