b - most commands accept this option to show the output page at a time (try "help -b" or "map -b" for example).
Hello KR1Ses, I hope this isn't too old of a post but this is the most recent thing I could find to help me with my unraid of the LSI 9211-8i HBA card to IT mode. If you are seeing mpr device sensor showing high temps, and a possible eventual kernel panic, you'll need to get a fan blowing on the card's heatsink.
On an EFI board the USB stick will show up as 2 options: "USB (NAME)" and "UEFI USB (NAME)" - choose the first for MSDOS and the second for EFI. Note that some motherboards come with onboard LSI chips; if yours has one then take great care and ask around what to do, before going further. Before you worry too much about it… the main goal at this time is to get the card to see the drives.
PCIe is very flexible - a PCIe3 card will work in a PCIe 2 slot at PCIe 2 speeds, or in a PCIe1x/2x/4x slot with fewer "lanes" and a reduced bandwidth limit.The PCIe bandwidth sets a total, overall, limit, meaning that if say 4 disks are idle, their "share" of bandwidth can be used by other disks that are doing high speed transfers. I am a programmer as my day job, and I can’t help but feel like there should be a simple fix for this. If the card or motherboard seems to become unresponsive or bricked because of the flashing process, these are the recovery instructions, but I should say I have never to do this, it's never been that bad.
I picked up two LSI 9211-8i 8 port SATA/SAS cards so I can add more than 8 drives to my FreeNAS box. But they don't always discuss the subtleties of doing it on an EFI board for users who may never have used EFI before, and there's a lot of relevant background that "falls in the cracks" and causes frustration when it doesn't go as expected.As long as you have the correct version of IT firmware (currently P20) on your 9211, FreeNAS should see all the drives you have connected through the expander.
No problem, you only need the bios if you want to boot from a device connected to the HBA, if not needed not having one just speeds up the booting process. The same is true for Windows and almost all other mainstream operating systems - if you tell it the boot device, it'll figure out the storage, any ZFS volumes, dynamic disks, or other stuff, when it boots. sas2flash -c CARD_ID -list - provides full details about each card (current firmware, bios, versions, sas ID, manufacturer, whether IR/IT, etc. But the cards often needs crossflashing for several reasons: They need to be switched over to IT not IR firmware versions ("IT" firmware means it's an HBA firmware which ZFS likes, while "IR" is a hardware RAID firmware which is strongly discouraged by most people for ZFS - the card can run either of these but often comes with the IR version loaded by default). There are 4 pins on the end, do I need to use a jumper or something to change so they are picked up by the 9211?I am pretty sure their RAID cards (L8i) can be reflashed to IT mode using their own flasher as well, but you can easily check this with Supermicro tech support if you find one that's cheap.
Great Deal
