Hi Folks,
I'm part of a team at a smaller non-profit scientific facility who's not a storage guy traditionally - just a Linux admin. Since we don't have a storage person, we're sort of figuring all of this out as we go.
We need to add a new DS212C to a dual-node FAS8200 cluster running ONTap 9.5P7.
All connectors are mini-SAS IOM12. This will be the 5th disk shelf in the stack.
I've read through the hot-add documentation and have done as much of the advance work as I can, including installing the latest DQP onto the cluster.
I have a couple questions I've not been able to answer for myself via the documentation:
1. I can't tell what type of multipath HA I have - whether it's Quad HA or not - there seem to be different cabling worksheets for each type of HA.
2. The worksheets seem to be "controller to stack", but since I'm adding a 5th shelf to a "stack(?)" of 4, I'm guessing this is a simpler job and might not have a worksheet?
3. What's the deal with turning off auto-assign and then turning it back on again? I'm not sure what we'll do next. There are 2 SVMs on the cluster, both are NFS space for the same VMWare cluster. I'm guessing maybe turning it off for the hot add, then turning it back on again should happen after we've confirmed the shelf is good to go? Then we'd assign that new disk space to the 2 existing SVMs?
Thanks for any help or advice related to this work that you're willing to give to an absolute newbie.
