Best way to replace faulted drive in a mirrored pair?

[jdebuhr]

Hey all,

I have 4 mirrored pairs and one pair hasa. faulted drive and possibly the second one will fault.. ANyway, both drives are under warranty ( Ironwolf 10TB) but I need to remove and send in prior to getting the replacements, I can remove them form the system and then ethe data migrates to empty space, but can I remove just the faulted drive? I see the replace function, but how does that work? Can I replace the HD even though it will not be for a couple weeks?

Here is the list showing the fault

I see the replace function, but how does that work?

The docs will answer this question. If you can't immediately replace the drive, offline it, and once you get the replacement (and have tested it), you can follow the replacement procedure from the docs.

But last time I had a Seagate drive fail under warranty, they offered advance exchange--they'd ship out the replacement drive, and once I had it tested and online I returned the old one. There was a nominal fee (US$15, IIRC), but well worth it IMO.

Thanks!!

I assume once the drive is replaced any data and synchronous that pair of drives will be available again..

Of course.
