Background:
Fresh installation, loader is 1.02b
Chips for 2 port extender ASM1061.
Chips for 4 port extender Marvell 9215
When you use PCIE (or Mini-PCIE) sata extender , the HDD slot may not be follow the sequence
For example. It gives HDD#1,2,5,6 instead of HDD#1,2,3,4
I did some reading in below links
https://github.com/evolver56k/xpenology/blob/master/synoconfigs/Kconfig.devices
It shows there are three command may help to re-arrange the HDD slot in order.
SataPortMap is define number of sata ports each of the sata host controller has
DiskIdxMap defines first sata port number for each of the sata host controller
sata_remap can help re-arrange SATAslot sequence ( not sure can re-arrange across different host or not)
I have tried play around with above three command with different setting. But didn't work out.
Because there isn't any successful examples that I have find.
Can any one share their successful examples
I have 3 scenario need to solve.
Scenario#1
Motherboard has 2 sata port #1 and #2 . PCIE extender 2 sata ports
DSM shows HDD #1,2,5,6 (skipped 3,4)
How to configure so that it shows HDD#1,2,3,4
Scenario#2
Motherboard has 4 sata #1-#4 . PCIE extender 4 sata ports
DSM shows HDD #1,3,5,6 (skipped 2,4). for 4 ports from motherboard, and HDD#7,8,9,10 for 4 ports from PCIE extender
I suspected this MotherBoard has 3 sata controller on it. I tried to config SataPortMap = 1124, but it didnt worked out
How to configure so that it shows HDD#1,2,3,4 (MB),5,6,7,8 (PCIE)
Scenario#3
Motherboard has 4 sata #1-#4 . PCIE extender 2 sata ports
When no PCIE extender connected. DSM shows HDD#1,2,3,4 (from MB)
Once PCIE extender is connected. DSM shows HDD#1,2 (from MB), 3,4(from extender), 5,6 (from MB)
It's like sata extender pushing port #3,4 to position of port #5,6
I suspected somehow the extender sata host has higher priority than the 2nd host on motherboard
How to configure so that it shows HDD#1,2,3,4 (From MB) ,5,6 (from extender) ?
Thanks a lot for reading and helping.
