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://kb.netapp.com/onprem/E-Series/Hardware/Unable_to_restore_DBM_on_controllers_in_lockdown_OELt___OELF 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 ... View more

Another non-question question from me, this time it's about Ubuntu, iSER and (of course) E-Series.   If you must or want to use Ubuntu and it has to be fast, iSER gives you hundreds of Gb/s for iSCSI over RDMA.   As Ubuntu isn't officially supported, it's best to reach out to NetApp and ask for qualification and instructions. But you can also go ahead and do it by yourself. My main recommendation is to use Mellanox OFED and that's all. Some additional details are available in [1].   [1] https://scaleoutsean.github.io/2023/09/22/ubuntu-lts-netapp-eseries-iser.html ... View more

We have a few E2600s that are now out of support. One of them seemed to have a controller failure recently, and somehow it got fully messed up in that the other controller got locked up, and the unit became unusable. Eventually we got the controller unlocked, but now that controller lost all the configuration and reports the unit as if it had never been configured. Wondering if there's a way to recover the configuration from the disks, before I completely give up and wipe away all the data. We could even move all the disks to a similar unit and try recovering there. But all my attempts have failed so far... Thanks for any pointers...   Jorge ... View more

I had a controller which lost Web UI access, but was pingable and has SSH Access. The second controller works fine. I have reseated the controller but am not able to bring it back online. No ping, Web UI doesn't recognize the controller and 7-digit display shows SE-88 which should be "Power-on default".   What can I do? ... View more
