kingtony911 Posted August 10, 2018 Share Posted August 10, 2018 (edited) Hello Everyone, Long time fan, first post ? Let me start by saying I have 2 server currently. One of them is running Unraid flawlessly for a few months now, love the software and all it can do! I am however having issues in one of my main servers. It is a 4U Server with 16 hard drive back plane. Currently have SAS9211-8I - Flashed to IT mode P20 (9211-8i_Package_P20_IR_IT_FW_BIOS_for_MSDOS_Windows) Intel Raid Expander Card RES2SV240 - (Not flashed or updated) Currently on the 9211 I have 1 cable plugged into the back plane (4 Hard Drives) and 1 cable running the expander (12 HD)... Mostly for testing. When I go into the 9211 interface it sees all 16 hard drives (Both HD on the expander and directly into the card), I have set the card not to post to BIO (per flashing instructions)... Before I set it to not show in the BIOS, the BIOS could see all the hard drives! When I boot up Unraid it only sees my SSD that is plugged directly into the motherboard. In the log files Unraid can see both cards. I have attached a diagnostics in hopes someone smarter then me can find something I did wrong.

Vr2Io Posted August 10, 2018 Share Posted August 10, 2018 (edited) From log driver can't load Aug 9 20:40:26 Tower kernel: mpt2sas_cm0: unable to map adapter memory! or resource not found Aug 9 20:40:26 Tower kernel: mpt2sas_cm0: failure at drivers/scsi/mpt3sas/mpt3sas_scsih.c:8955/_scsih_probe()! My server with 9211 + expander also set not post in BIOS, no problem with unRAID. From your log, would you try Aug 9 20:40:26 Tower kernel: pci_bus 0000:00: Automatically enabled pci realloc, if you have problem, try booting with pci=realloc=off Edited August 10, 2018 by Benson Quote Link to comment
JorgeB Posted August 10, 2018 Share Posted August 10, 2018 You can also look for a board bios update and try a different PCIe slot if available. Quote Link to comment

A different PCIe slot is a good idea to test. When writing Linux drivers, I have had hardware that have failed to map memory and the problem have been solved by using different slots or by changing the order of detection in the kernel. But the pci realloc message is also meaningful to follow. Quote Link to comment

When I was first T/S this issue I did move the raid card to a different PCIe slot with the same results. added the following to my /boot/syslinux/syslinux.cfg append pci=realloc=off initrd=/bzroot Per this post Now i can see ALL OF MY HARD DRIVES!!!! thank you everyone for your help. Quick question, which has been asked before. What is the down side of what i did? Thanks Tony Quote Link to comment
pwm Posted August 10, 2018 Share Posted August 10, 2018 2 minutes ago, kingtony911 said: What is the down side of what i did? Most probably none. The realloc logic is to handle cards that have resources outside of the first 4 GB of memory address space - i.e. outside the range a normal 32-bit application or a 32-bit hardware can reach. And the realloc can fail if there isn't free space in the required address range. But unRAID runs 64-bit code and there aren't much hardware that are strictly limited to 32-bit address range. Switching PCIe slot shouldn't matter either unless you had to switch to a slot that has fewer/slower PCIe lanes resulting in less bandwidth to the controller card. Quote Link to comment
kingtony911 Posted August 10, 2018 Author Share Posted August 10, 2018 Hey Everyone, again thank you for the help. I am still new to the boards. Can someone mark this as SOLVED please? Quote Link to comment
