Description Josef Bacik 2007-01-11 16:09:16 UTC 
Description of problem:
Ok apparently iLo2 interfaces not only have an ssh server that responds way 
too slow to use the normal fence_ilo script on it, but they also may not have 
an IPMI interface.  Most iLo2 interfaces come equipped with IPMI capabilites, 
which you can use fence_ipmi with the lanplus option to make it work, but 
apparently on some blades the IPMI capability does not exist.  There is yet 
another way to work with the ilo2 interfaces, they have a telnet server which 
you can do power management through.  This script is adapted from the 
fence_rsa script and has been tested with one of these non-IPMI iLo2 
interfaces and it works.

How reproducible:
Every time.

Steps to Reproduce:
1. Buy a HP box with a watered down ilo2 interface
2. try to use fence_ilo or fence_ipmi with the lanplus option
  
Actual results:
with fence_ilo the ssh connection times out trying to connect to the ilo2 
interface, and if you have the watered down version of the ilo2 interface 
fence_ipmi with the lanplus option will complain loudly about the interface 
not having IPMI capabilities.


Expected results:
Should just reboot the box like a good fence script.

new fence_ilo2 script

Ok apparently when we pass options via stdin we get the \n on our options,
which is fine for ipaddr/login/passwd etc, but for option we do comparisons,
which screws up so option is ignored when passing it via stdin.  This new
script does an rstrip() on the option string before checking it to rip off the
newline, its been tested and it works.

What we actually need in bugzilla is a "Need Hardware"  state! Thanks for the
script, josef. I would really like to integrate ilo and ilo2 agents into one
agent script that just does the correct thing, so that users did not have to
specify fence_ilo or fence_ilo2 in the conf file. I need an ilo2 enabled blade
to test this on, though. As of today, Feb. 07, 2007, I was told I would be
receiving some about 3 weeks ago.

Josef, could you test the script I attached above on your hardware? It uses the
SSL interface, and I've tested it on firmware "iLO Advanced 1.26 at 10:01:40 Nov
17 2006" (RIBCL 2.22).
Comment 6 Josef Bacik 2007-02-19 19:41:21 UTC 
unfortunately I don't have any hardware, I've been relying on customers to 
test stuff.  I will hit some of the techs of previous customers and see if 
they will test it.
Comment 7 Ryan McCabe 2007-02-20 22:09:05 UTC 
We found another box with an ilo2 card here in Westford, and the script works
correctly there, too, so I've checked it into CVS.
