Tunable hint.isp.N.role

[revengineer]

Hello,
I noticed that sometime between my original update to Truenas 12.0-U4 and the current verion 12.0-U7, tunables hint.isp.N.role where N=0-3 were added to my system. My understanding is that these are for fiber channel support which I do not use or have. Should I delete these tunables?

Thank you.

@revengineer I see the same thing with 12.0-U8 and I don't have FC either

I am afraid to just delete them without getting expert feedback.

If you don't have Fibre Channel hardware, it doesn't hurt to delete these tunables. However, if you observe the console boot messages with dmesg, these get recreated on every boot. I wouldn't worry too much about these tunables.

Thank you @Samuel Tai. In this case, I will not fight these tunables.
