FFS! Needed to Expand Advanced Settings. Been one of those days!
Hi, I have 2 of these hosts and vCenter says: "TPM 2.0 device detected but a connection cannot be established" I haven't changed anything in the TPM settings. I've looked at the VMware docs and they say: To use a TPM 2.0 chip, your vCenter Server environment must meet these requirements: -vCenter Server 6.7 or later-ESXi 6.7 host or later with TPM 2.0 chip installed and enabled in UEFI-UEFI Secure Boot enabled-Ensure that the TPM is configured in the ESXi host's BIOS to use the SHA-256 hashing algorithm and the TIS/FIFO (First-In, First-Out) interface and not CRB (Command Response Buffer). For information about setting these required BIOS options, refer to the vendor documentation. I'm looking in the BIOS and I cannot see these options: that Dell docs say is "TPM Algorithm"UEFI Secure Boot - I just see a "Boot Mode" option, which is set to UEFI. Normally I see a UEFI Secure Boot alongside this option. I do see a Secure Boot option under TPM Advanced Settings but this is a different thing - I've NEVER seen Secure Boot put under TPM options!
