Hi @Egghead_Systems , First of all, the reason you and I went to maintence mode is because of new feature that installed from 8.1.1, called " Software Integrity Check". You can find this under release note. https://docs.paloaltonetworks.com/pan-os/8-1/pan-os-release-notes/pan-os-8-1-release-information/features-introduced-in-pan-os-8-1/management-features.html As TAC told me, PAN-OS detected some files were broken, such it stoped normal start up operation and went to maintence mode. After you see entering maintence mode, you can find log from fips.log on the menu and see which specific file was failed. The log below is my sample: === 10/14/19 15:31:09 fips ERROR: failed integrity check on /etc/pan-manifest/mgmt-panos(//var/appweb/sslvpndocs/global-protect/getsoftwarepage.esp: FAILED) 10/14/19 15:31:09 fips ERROR: FIPS-CC integrity on fs:Management plane failed verification on 1 files. 10/14/19 15:31:09 fips ERROR: * * * * * FIPS Self-Tests failed * * * * * 10/14/19 15:31:41 fips ERROR: * * * * * FIPS Self-Tests (**panic**) trying os command * * * * * === From above situation, we can take two ways: 1) try to proceed factory reset and see broken files are replaced by original files (don't forget to take your config backup before you proceed) 2)open the ticket, and request RMA On my case, we did RMA... I could not escape from maintence mode and found no way.
