ESXI 6.7 config lost after reboot

[Grimeire]

Hey,

Since i have update to ESXI 6.7.0 Update 3 (Build 15160138) which is booting from a USB, I noticed that after a reboot that the config is lost. ESXI is running on a Dell T20.

I tired a number of things that i found when browsing the forum but nothing seems to work.

1. ran autobackup

/sbin/auto-backup.sh
Files /etc/vmware/dvsdata.db and /tmp/auto-backup.2100458//etc/vmware/dvsdata.db differ
Saving current state in /bootbank
Clock updated.

2. backup of config and restored it.

vim-cmd hostsvc/firmware/backup_config

scp Downloads/configBundle-esxi.tgz esxi:/vmfs/volumes/nvme/

vim-cmd hostsvc/maintenance_mode_enter

vim-cmd hostsvc/firmware/restore_config /vmfs/volumes/nvme/configBundle-esxi.tgz
Connection to 192.168.0.50 closed by remote host.
Connection to 192.168.0.50 closed.

3. ran backup script but it appears to fail

/sbin/backup.sh
Usage: /sbin/backup.sh IsShutdown [PATH_NAME]

Anyone have any other suggestions on how I can get the config to persist?

Are you seeing in BIOS USB detected or not if yes , what is the error at the time of booting,

What do mean?

if it was not detected then ESXI would it not boot?

what ever the cause of this is the issue seems to be running ESXI from a USB.

i setup ESXI from a usb again and within a couple of months the same issue happened again.

I then setup ESXI on a SSD and its been running without any issues for 3 months now.
