If no staggered sign-up causes some voltage drop, it will affect only in HDD box, perhaps it is 12V power line drop. SiI3726 will use 5V power line with regulator (IO = 3.3V, core=1.8V) so influence will be small. Whether send SRST or not, no HDDs are linked up at that time and it must wait for a while with repeating hard reset. Current behavior is "try 3 times and ignore". If the behavior is changed to "try 4 times and ignore", the behavior of most HDD box wont be changed because all HDDs are linked up before 4th try. For users who has slow spin-up HDDs, they get more some seconds. I think it is convenient for most users and easier than trace/fix my problem. Of course the solution that solves my problem with SRST is best! > Gwendal. >>> I notice however some messages I did not see before: >>>>> [ 4.856382] ata7.15: Port Multiplier 1.1, 0x1095:0x3726 r23, 6 ports, feat 0x1/0x9 >>>>> [ 4.858742] ata7.00: hard resetting link >>>>> [ 14.843039] ata7.00: softreset failed (timeout) >>>>> [ 17.836402] ata7.15: qc timeout (cmd 0xe4) >>> The later indicates that the PMP is stuck and the host can not read >>> its internal register. >>> Is it possible that the PMP in these 4 enclosures you are using have a >>> different firmware than the other ones? >>> Firmware 1.0114 is available at: >>> http://www.siliconimage.com/support/searchresults.aspx?pid=26&cat=23 >>> >>> From the release notes: >>> """- Fix SRST and initial two RegFIS Problem.""" I'm still fixing broken RAID. Sorry for my slow response.
