In this KB we briefly introduce various tools that exist for remote and/or local management of OOBM. This is particularly useful when DRAC/iLO/BMC become unresponsive or credentials don’t work.
There are four tools that could be useful depending on the model of the server and out-of-band management:
ipmitool, ipmiutil, racadm and impish
These tools can be used locally or remotely.
1- ipmitool : This tool can be used both locally and remotely. If the oobm has IP and credentials work we can use this remotely. It can be installed on CentOS using “yum install ipmitool” Here are some examples for remote
The interface switch -I can get one of the values values “open, lan ,lanplus”. open is the default and for local access. lanplus is for IPMI version 2.0 and lan is for IPMI version 1.5
# ipmitool -I lanplus -H 208.x.x.x -U root -P xxxxx chassis status
# ipmitool -I lanplus -H 208.x.x.x -U root -P xxxxx fru
# ipmitool -I lanplus -H 208.x.x.x -U root -P xxxxx power status/cycle/reset/soft/off/on
# ipmitool -I lanplus -H 208.x.x.x -U root -P xxxxx mc reset cold/warm
# ipmitool -I lanplus -H 208.x.x.x -U root -P xxxxxx lan print 2
If the network is not configured or credentials don’t work we can try to change OOBM parameters from local OS, If OS is installed and can be accessed remotely. The parameter -I open is default so it is omitted.
# ipmitool power status (if this returned an error we need to load the following kernel module)
# modprobe ipmi_devintf
# modprobe ipmi_si
# ipmitool chassis status
# ipmitool mc reset cold
# ipmitool lan print 1
# ipmitool lan print 2
# ipmitool user set name 2 root
# ipmitool user set password 2
# ipmitool channel setaccess 1 2 link=on ipmi=on callin=on privilege=4
# ipmitool user enable 2
2- ipmiutil: This tool is available for both Windows and Linux. However for Linux we don’t use it and only use ipmitool.
Here are some examples:
C:\ipmiutil-2.9.5-win64>ipmiutil reset -k -N 10.10.x.x-U Administrator -P xxxxx
ipmiutil ver 2.95
ireset ver 2.95

3- racadm: This is also available for both Windows and Linux. It is also part of Dell’s OMSA. For example if we boot the server with live OMSA disk both ipmitool and racadm are available. This also can be used remotely or locally. racadm has both 32bit and 64bit versions. Make sure to use the 32bit version as 64bit doesn’t work with some DRACs (For example DRAC 4/P)
32bit: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=FT3XR
64bit: http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=0H4MT
# racadm racresetcfg (resets to factory default, for example user becomes root with password calvin)
# racadm setniccfg -s
# racadm racreset
# racadm setniccfg -s <ipaddress subnetmask gateway>
# racadm -r <RAC IP address> -u <username> -p <password> <RAC command and options>
# racadm -r <RAC IP address> -i <RAC command and options> (asks user/password interactively)
In windows:
“C:\Program Files (x86)\Dell\SysMgt\rac5\racadm.exe” -r <IP> -u <username> -p <password> racreset
4- ipmish: we use this for remote access from windows:
ipmish -ip 192.168.x.x -u <username> -p <password> power status/cycle/on/off/reset

Download the file https://10.x.x.x/M2.JAR and open it using Java.
If it cannot be downloaded locally we can download it in RIS then copy it to local environment.
