exodius Posted April 17, 2022 Share #1 Posted April 17, 2022 (edited) Hello, After searching a lot, and testing for hours, i've found something that doesn't seems to in this forum (if it is; sorry i haven't seen it) I've found 2 PERC H310 inside the bin, and saw the fabulous REDPILL LOADER, so i decide to give both a try. Got some usb stick and free disks, i first follow the classic H310 to 9211-8i IT firmware flash (google for it, it's pretty easy to do) Tryed the redpill loader with my new HBA SAS2008 : worked !!! BUT, the drives never show up in the correct order. Worse : the order changed uppon reboot. I found this great litterature to help me understand : S11209_v1.0_SAS-2EnclosureMapping.pdf There is a solution to switch those nice HBA from SAS address, to enclosure/slot mapping mode. Please note that my enclosure is a supermicro with a BPN-SAS-825TQ backplane, with SFF8084/sata breakout cables pluged between the backplane and the LSI SAS2008 card 2 counterbacks : - The order of the disks is reversed. Cable #1 for port A goes to disk 7, and cable #4 for port B goes to disk 0 - If there is a missing disk at boot, the card will bypass it, and it will allows report the disks in continuous order. ie. if disk 3 of 8 is missing at boot, then you will see that disk 8 is missing in DSM. Here is what i have done for this result : - Create my usb stick with redpill, and DSM - Plugged only the first disk in the enclosure, at the first position (important !) and then install DSM. If your NVRAM is not blank from a fresh flash, make a freedos USB stick with sas2flsh and launch sas2flsh -o -e 3 (this will erase the info from previous drives, and more config, becarefull) - Launch DSM7, got to ssh and : wget https://github.com/thomaslovell/LSIUtil/raw/master/Binaries/LSIutil_1.71_binaries/Linux/lsiutil.x86_64 chmod +x and sudo run ./lsiutil.x86_64 go into option 9, pagetype 1, pagenumber 8 modify offset 0x0c to 02 (bit 1 = Enclosure/Slot mapping mode) reboot and enjoy. Note that you can see the disk order with the LSIUTIL tool, using option 16 Fell free to make any comments or ask any questions Edited April 17, 2022 by exodius added option 16 info 2 2 Quote Link to comment Share on other sites More sharing options...
