Hi All,
I have an inherited environment where there is a mish mash of load sharing SVM root vol mirrors - some setup and running to some of the nodes, some uniniatilized and some with none at all - set up by my predecessor (who no longer works for the company).
I am trying to bring some order and sense to this, but no one at my current employer can give me a straight answer whether they are needed or not, and I have a case open with NGS, but we seem to be going round in circles, with them just pointing me to documentation that contradicts each other and asking me to delete and re-create the mirrors.
What I would like to establish is if they are even required in the first place - my previous employer had 2 6node clusters and did not use LS mirrors at all. Another ex-colleague also says he does not use them, and they went out with 8.3x (I know volume LS mirrors are deprecated but these are SVM root volume LS mirrors).
In our current environment we are on ONTAP 9.1P9 and have a 12 node cluster and 45 SVMs (yes, really) so following what I can glean to be the best practices for this version we should have a LS per SVM root vol, so that would be approx 45 x 12 = 540 mirrors (which is simply ridiculous). We are working on a plan to get to 9.7 (and then possibly up from that to maybe 9.8 or 9.9) but this will take a few months at least due to hardware swapouts etc.
Can any of the Netapp ninjas out there offer any advice on this ?, what do you do?
