Another E2600 disaster. Can it be restored?

agapotron — Wed, 04 Jun 2025 13:09:38 GMT

We have an E2600 that has gone into lockdown mode. It all started with a report of a failed drive. Simple enough, we took a similar drive from one of our spare units and replaced the drive. Immediately, the unit went into infinite reboot mode. Well, not infinite, since it stops after 5 attempts. But here's what it reports (when connected to the serial port):

Any suggestions on what we can do to recover the data? The unit is old and out of warranty. We do have some saved files for the unit under /var/opt/SM for our santricity monitoring system. I would think the data on the disks is still good except for the one failed drive, but the unit was using disk pools, and it should be able to withstand a couple of drive failures... Of course, this unit was being used to backup our main system, and as soon as we lost the unit we find ourselves in need of the backed up data. So, any help would be extremely appreciated. Thanks!

Looking at the error messages and after consulting with some of our experts internally, I'd recommend that you reach out to NetApp support since the recovery process could be pretty involved.

I have reached out to NetApp support, and they weren't very helpful. They chastised me for not having the unit under maintenance, and said the unit is end-of-life, so why are we using it anyway? Eventually, they almost grudginly agreed to give me a quote (which they mentioned is probably going to be very expensive) to place the unit back on maintenance so that then they can begin to investigate if they can do anything about this. At this point I'm wondering if there are any other options out there...

Getting the unit back under maintenance would be the best course of action.
