Thanks Digimer for the reply.
Was able to verify that proper alphabet case is being used for 'Administrator' user.
====
# fence_ipmilan -L ADMINISTRATOR -a 192.168.2.153 -P lanplus -l Administrator -p "XXX" -T 4 -o status -v
Getting status of IPMI:192.168.2.153...Spawning: '/usr/bin/ipmitool -I lanplus -H '192.168.2.153' -U 'Administrator' -L 'ADMINISTRATOR' -P '[set]' -v chassis power status'...
Chassis power = Unknown
Failed
====
Looks like it was not taking the default password for 'Administrator' user.
====
# ipmitool user test 1 20 XXX
Set User Password command failed (user 1): Unknown (0x80)
Failure: password incorrect
# ipmitool user test 1 16 XXX
Set User Password command failed (user 1): Unknown (0x80)
Failure: password incorrect
-----
# ipmitool user test 2 16 xxxx
Success
# ipmitool user test 2 20 xxxx
Success
====
Changed privilege for 'admin' user to ADMINISTRATOR so that it can perform fencing.
====
]# ipmitool user list 2
ID Name Callin Link Auth IPMI Msg Channel Priv Limit
1 Administrator true false true ADMINISTRATOR
2 admin true false true ADMINISTRATOR
====
Digimer , can you please let me know whether for performing fencing , ADMINISTRATOR level privilege is needed or lower privilege levels can perform fencing ?
===
1 Callback level
2 User level
3 Operator level
4 Administrator level
===
Thanks
Zaman
