Unable to unlock SED drives after boot drive died

[abhijeet1301]

Hello, this weekend has nothing but a nightmare for me. I am really hoping experts would be able to help me out here. I had a Truenas Scale running on Supermicro 6048R-E1CR72L with 60 * 18TB SED drives that I use for backups and backups only. I followed this guide to encrypt my drives https://www.truenas.com/docs/core/c...vanced > SED,System > Advanced > SED Password. and all was fine for a week or so. Low and behold the boot drive got offline and upon checking we found it would just not show up. We booted a new scale this time and the pool wouldn't import even after using the correct password in advanced field. The support staff panicked and ran below commands in order to clear the key:
sedutil-cli --disableLockingRange 0 password /dev/sda
sedutil-cli --setMBREnable off password /dev/sda

After above commands the drives still wound say locking enabled as Y then they ran
sedutil-cli --eraseLockingRange 0 password /dev/sda

At this point I cannot import the pool nor I can disable the locking of my drives
