Welcome Readers!
In this blog, we will be moving ahead to understand the process of ESXi Installation & the ways of its maintenance.
ESXi Installation:
--> ESXi can be installed through following options:
--> USB : Create bootable drive (that can run ESXi off the USB to physical host)
--> CD/DVD: Write the image to a disk
--> Auto Deploy: Store the image on a Auto Deploy depot (includes Network Boot)
* Cannot be used for 1st ESXi setup in the environment
DCUI (Direct Console User Interface):
This is the method of accessing ESXi terminal directly.
There are various options to operate from it:
- Root password change
- Lockdown Mode (way to secure terminal)
- Management Network
- Troubleshooting Options
- System Logs
- Support Information
- Reset Configuration
Lockdown Mode:
It is a security feature that prohibits anyone from accessing the DCUI except the root user.
Once it is enabled host must be managed from vCenter server only (except root)
This option would be greyed out if the ESXi host is not connected to a vCenter server.
Troubleshooting Options:
DCUI allows us to enable or disable following options:
- ESXi Shell
- SSH
- Modify SSH & shell timeout
- Restart Management Agents
Host client is similar to web client, but we cannot connect to vCenter using the host client. It provides one to one management of ESXi host only.
It can be installed by browsing the IP address of host.
Host to vCenter communication port is 902 (vCenter heartbeat port)
Thats all for this blog! See you in next module!
Happy Reading! Happy Learning!
Simplified as we need!
