Intelligent Platform Management Interface
Each cluster is equipped with Serial Over LAN connectivity features via Intelligent Platform Management Interface (IPMI) allowing for complete management of each node at any power state. This provides accessibility to the system while powered off, through boot cycles, and during live operation. In order to utilize these features, you must first create a user and enable it on each device. Below are the steps for creating a new user and some of the common commands you may wish to utilize at different stages of your cluster's operation.
To access the node via SSH, you will first need to be connected to the HyperCloud Dashboard. From there you will be able to locate the required IP to Open the Serial Over LAN session. These instructions can be found at HyperCloud Dashboard Console IP.
On Node
Create and Enable IPMI User
Remotely connect via SSH to the IP of one of your nodes (refer to the equipment register in your portal for system IP addresses).
Also, to show all of the currently defined users and ID slots available for creating additional users, use the command below:
root@hypercloud-compute-kvm-e0fff7001d03:~# ipmitool user list
ID Name Callin Link Auth IPMI Msg Channel Priv Limit
1 true false false USER
2 ipmiusr true false true ADMINISTRATOR
3 true false false Unknown (0x00)
4 true false false Unknown (0x00)
5 true false false Unknown (0x00)
6 true false false Unknown (0x00)
7 true false false Unknown (0x00)
8 true false false Unknown (0x00)
9 true false false Unknown (0x00)
10 true false false Unknown (0x00)
11 true false false Unknown (0x00)
...(truncated)
Next, you need to set the username and password.
ipmitool user set name 10 "mynewuser"
ipmitool user set password 10 "p@ssw0rd"
ipmitool user enable 10
ipmitool channel setaccess 1 10 privilege=4
Identify Node
An orange light on the front of the chassis will blink per "interval" in seconds. Default interval is 15 seconds. Use 0 to turn it off or "force" to turn on indefinitely.
Changing BMC from DHCP to Static IPs
If the need to change the BMC from DHCP to a static IP address scheme arises, follow these steps on each node:
Single node example:
ssh root@172.31.2.112
ipmitool lan set 1 ipsrc static
ipmitool lan set 1 ipaddr 192.168.0.100
ipmitool lan set 1 netmask 255.255.255.0
ipmitool lan set 1 defgw ipaddr 192.168.0.1
Remote Login
Open Serial Over LAN Session
username and password are both case-sensitive
