When an engineer wants to create a 4-node cluster after rack and stack, they must use theiDRAC (Integrated Dell Remote Access Controller)port to start the installation.
Understanding iDRAC:
Remote Management:
iDRAC provides out-of-band management capabilities, allowing administrators to manage and monitor nodes remotely.
Virtual Console Access:
Offers a virtual console for accessing the node's BIOS and performing installations.
Initial Cluster Setup with iDRAC:
Accessing the Node:
Connect to each node's iDRAC interface using its IP address.
Starting the Installation:
Use the iDRAC virtual console to interact with the node as if you were physically present.
Benefits:
No need for physical access to the COM port or direct console connections.
Allows for remote configuration and reduces the time required for setup.
Why iDRAC is Used Over Other Ports:
COM Port:
The COM (serial) port can be used for initial setup, but it requires physical access and serial cables.
Less convenient compared to iDRAC's remote capabilities.
FE (Front-End) and BE (Back-End) Ports:
FE and BE ports are used for data network connections, not for initial setup or management.
The initial configuration cannot be performed through these ports.
Procedure for Using iDRAC:
Step 1: Connect to iDRAC
Ensure that iDRAC network interfaces are connected and configured with IP addresses.
Access iDRAC via a web browser using the IP address.
Step 2: Launch Virtual Console
Log in to the iDRAC interface.
Launch the virtual console to access the node's system interface.
Step 3: Perform Initial Configuration
Use the virtual console to run the OneFS installation wizard.
Configure cluster settings, networking, and other parameters.
