While installing the ESXi VMware-VMvisor-Installer-8.0 i was warned that "the disk will be repartitioned" , upon the installation I saw 0 in the storage , tried attaching the new datastore however the message was " failed to create VMFS name" , then I tried increase the capacity and prompted with a fatel error as attached . Could someone help me advise on this ?
According to the provided screenshots, there's no free disk space available for a datastore.
Please don't mix up the "VMFSL" partition with a "VMFS" partition (a datastore).
With ESXi 7.0, VMware increased disk requirements for the ESXi installation, where up to ~130GB (depending on the disk size) can be used by ESXi itself.
In case that this is your only disk, and you want to have some disk space for VMs (a datastore), you may follow https://kb.vmware.com/s/article/81166.
