Description Luigi Toscano 2011-05-18 14:38:22 UTC

Description of problem:
Configure the machine as power management-enabled execute node. 

StartLog contains:
ioctl(SIOCETHTOOL/GWOL) failed: Operation not supported (95)

This seems to be the same issue:

Version-Release number of selected component (if applicable):
condor-7.6.1-0.5

Comment 1 Timothy St. Clair 2011-05-18 20:48:09 UTC

?'s:
1.) What type of hardware+BIOS variations are you testing?  
2.) Does this happen on *RHEL6 boxes across multiple vendors?
3.) What eth adapters are you seeing failure on?

It is entirely possible that the NIC may require a custom setting to enable WOL packets. 

Also do not try this in a VM.

It was a Dell PowerEdge SC1435 server. The machine has been already
returned to the pool. I will have a look at it either today or on Monday
next week - as soon as there is similar machine available.

The network interface is: NetXtreme BCM5721 Gigabit Ethernet PCI Express

Comment 4 Timothy St. Clair 2011-05-23 14:08:28 UTC

Could you run:

ethtool eth0 (or whatever adapter it is using) 

... 

And verify: 

" Supports Wake-on: pumbag
  Wake-on: g "

Comment 5 Jan Sarenik 2011-05-23 14:11:30 UTC

Current status is

# ethtool eth0 | grep Wake
	Supports Wake-on: g
	Wake-on: g

but it was "Wake-on: d" before I applied the manual change
mentioned in HP docs regarding the tg3's wake-on-lan:

Comment 8 Luigi Toscano 2011-05-24 17:38:22 UTC

It seems that I can't reproduce anymore; I tried both machines with adapter controlled by the tg3 driver and the bnx2 driver, RHEL6.1. condor recognizes WOL even if the value of 'Wake-on' in the output of ethtool is not included in the  'Supports Wake-on:' field. Therefore I'm closing it.
