SuperMicro JBOD’s can be attached through a straight patch cable to its server.

If not set the JBOD, tries to find a DHCP server, if it can’t, it automatically sets as a default address 192.168.1.99.

In order to access and configure the JBOD you need to add an IP address to the interface, to which it is attached, and bring it up:

ip addr add 192.168.1.98/25 dev eno3
  ip l set dev eno3 up

Wait for few seconds to get the changes activated properly before trying it out:

ping 192.168.1.99

Default user/password in the JBODS are ADMIN/ADMIN.

To print the IP settings:

ipmitool -I lan -H 192.168.1.99 -U ADMIN -P ADMIN lan print

To get a log:

ipmitool -I lan -H 192.168.1.99 -U ADMIN -P ADMIN sel list

To get sensor list and their data:

ipmitool -I lan -H 192.168.1.99 -U ADMIN -P ADMIN sdr elist all 

To get the status of the power of the JBOD and restart it:

ipmitool -I lan -H 192.168.2.6 -U ADMIN -P ADMIN chassis power status
ipmitool -I lan -H 192.168.2.6 -U ADMIN -P ADMIN chassis power off
ipmitool -I lan -H 192.168.2.6 -U ADMIN -P ADMIN chassis power on

Since there can be more than one JBODs per server it is reasonable to change the IP address of the JBOD’s and the interfaces to which they are connected.

A reasonable configuration proposal for two JBODs attached, to to different interfaces could follow this proposal:

  #Network 1 
  192.168.2.0/30
  #IP addr 1 on HOST interface 
  192.168.2.1
  #IP addr 1 on JBOD interface 
  192.168.2.2
  
  
  #Network 2
  192.168.2.4/30 with 192.168.2.1192.168.2.3. In such way both
  #IP addr 2 on HOST interface 
  192.168.2.5
  #IP addr 2 on JBOD interface 
  192.168.2.6

Here is how you change the IP addr on the interface and the JBOD:

  #First add an additional ip to the host interface
  ip addr add 192.168.2.1/30 dev devName
  #change JBODs  ip with timeou
  timeout 15 ipmitool -I lan -H 192.168.1.99 -U ADMIN -P ADMIN lan set 1 ipaddr 192.168.2.2

To make the host interface change permanent you need to edit its network script.
