Netapp E2660 lockdown OELt / OELF

[SkillUser]

Good afternoon. After several power cuts, the system locked up with OELt/OELF errors. I brought the system out of the lockdown mode using the commands
clearHardwareLockdown
psvClearSodRebootLoopCounter
lemClearLockdown .
The system started up, but there is no data on it.
I've looked through these KBs, documentation, and communities:

https://docs.netapp.com/us-en/e-series-cli/commands-a-z/load-storagearray-dbmdatabase.html#context

https://community.netapp.com/t5/EF-E-Series-SANtricity-and-Related-Plug-ins/E2600-Disaster-Recovery/td-p/117754

I need a validation key for recovery.
Can someone help me with this?
The system is very old and no longer supported!
Thank you for your help

I don't know how to help you, it's not my area of expertise. Do you have any other ESERIEs which has a valid support. If you have a valid support account and you are able to access your profile and log a case (may be non-technical), just to get some sort of feedback from NetApp on what are your options.

Good afternoon. I fully restored the system using the script "load storageArray dbmDatabase sourceLocation=onboard contentType=all"
