I'm trying it but it isn't stable. Boot fails frequently in warm reboot.
When boot fails, I can only see a swap partition. So, I can get no logs.
I'll try little more.

I have attached the log of power cycle. Boot was successful. This log
contains all ata1 -- ata10 information.

I think that I have switched like this:
ata5 <--> ata7
ata6 <--> ata8

ata7,ata8 : 4+4=8 HDDs.
ata5,ata6,ata9,ata10 : 5+5+5+5=20 HDDs.

But from log,
ata5: 2 HDDs -- lost 3 HDDs.
ata6: 3 HDDs -- lost 2 HDDs.
ata7: 4 HDDs -- OK.
ata8: 4 HDDs -- OK.
ata9: 3 HDDs -- lost 2 HDDs.
ata10: 4 HDDs -- lost 1 HDD.

Thank you for your help.

Best Regards,
Akira
