Some logs:

Feb 21 21:56:04 afs-6 stonithd: [32048]: debug: external_run_cmd:  
Calling '/usr/lib/stonith/plugins/external/ipmi status' returned 256
Feb 21 21:56:04 afs-6 stonithd: [32048]: debug: external_run_cmd: '/ 
usr/lib/stonith/plugins/external/ipmi status' output: error executing  
ipmi command
Feb 21 21:56:04 afs-6 crmd: [9918]: ERROR: process_lrm_event: LRM  
operation resource_ipmi_afs-8:0_monitor_60000 (call=1721, rc=1) Error  
unknown error
Feb 21 21:56:08 afs-6 stonithd: [32093]: debug: external_run_cmd:  
Calling '/usr/lib/stonith/plugins/external/ipmi status' returned 256
Feb 21 21:56:08 afs-6 stonithd: [32093]: debug: external_run_cmd: '/ 
usr/lib/stonith/plugins/external/ipmi status' output: error executing  
ipmi command

This happens sometimes, but 'ipmi status' will be called every minutes  
(I set a monitor oper on these ipmi resource), and I DO verify this  
monitor behavior by tcpdump the IPMI traffic.
