Dell SAS6IR is it worth the effort to convert to IT
Hi, I'm in the process of setting up an old PowerEdge R410 which has, I believe, the LSI Logic AS1068, using the mpt driver. I'm not interested in running it as a hardware RAID but rather a geli(authentication only)+gmirror+gjournal. It seems like flashing it requires booting into dos, which frankly I can't be bothered with. mptutil doesn't appear to have that capability. Are there any major downsides to running it in IR mode as two disks? There's no option to turn off the write-cache, but being battery backed the only danger I see with that is if the machine is powered with pending writes on the card and the battery gives out before power is restored. The use case is routing/snort IPS with minimal logging, so disk performance isn't critical. It will be the redundant router so mostly doing nothing except the little work OSPF needs.

If you don't create a RAID array it behaves exactly like an IT controller. And yes, FreeBSD mptutil doesn't have the ability to erase the flash, which you need to be able to do to go from IR to IT. DOS is the typical answer for that. -- Thanks, Josh Paetzel ___ freebsd-hardware@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "freebsd-hardware-unsubscr...@freebsd.org"

Trying to install on Dell Latitude 7390 (UEFI, NVMe)
(originally posted on the FreeBSD forums, was advised to post to this mailing list instead) So it's been a while since I tried setting up FreeBSD from scratch on bare metal, but I wanted to set up a laptop again. For this, I grabbed a Dell Latitude 7390 with an NVMe SSD so UEFI is required. However, I have Secure Boot disabled and Legacy boot ROMs enabled in the BIOS. I'm not trying to dual-boot or anything... wiped the SSD clean and starting bare. I installed the USB installer image (11.2-RELEASE) on a USB flash drive and I boot from it via UEFI. I get as far as the partition step and its confirmation, and then get "Device busy". I realize UEFI w/ FreeBSD is tricky (buggy?) but I'm hoping there's a way through this and that I'm doing a simple something incorrectly. I've never tried setting up FreeBSD w/ UEFI before.
