Step 1. Login to VMware ESXi GUI (replace <your_ip_address_or_hostname> with the correct ip/hostname)

https://<your_ip_address_or_hostname>

Step 2. Click on Virtual Machines

Step 3. Shut down the VM for which you want to increase disk space

Step 4. Select the VM, then click on Edit

Step 5. Click on the Hard disk you want to increase the disk space, then increase size of the VMDK and click on Save

To increase the size of a VMDK, update the value of "Hard disk 2" by entering the new total size (current size + additional space).

For example, if Hard disk 2 currently has 50 GB and you want to add another 50 GB, set the new size to 100 GB.

Step 7. Increase virtual machine partition

Use the tools within the virtual machine (Windows or Linux) to extend the partition after increasing the virtual disk size.
