Can you upgrade ONTAP with a broken/failed drive in the system or do you need to get it replaced first ?

We are updating large clusters with some broken disks (old nodes in cluster) all the time, works, but not recommended for obvious reasons.

#

With many 1000s of disks, the time window of no broken disks is very narrow.

I've seen it turn into a pile of hurt more times than I've seen it work. YMMV

#

our advice is to not perform ontap upgrades with broken disks present

#

you can do the update with broken disks. The worst thing that could happen is that the reconstruct of the broken disk might re-start from scratch but that is rarely a problem

Again, my customers experiences have not been good doing it. Perform ontap upgrades with failed disks present at your own risk

Unlike the big I storage vendor which refused to do an upgrade with a broken drive. More than once, I had a drive fail the night before an upgrade maintenance window and had to cancel my change.

I was mid-headswap once where one of the root aggr disks failed. that was fun.

20 node cluster minor update done for SMB signing issue. 12 broken disks, maybe 1 failed after the update. Only issues were LIFs failing over to wrong (not HA partner) nodes and one node stuck in LOADER, simple as always.
