Hey,
just bought an eSATA/USB dual drive docking station and my CentOS 5 can only see one drive at a time... Any one knows if there are specific parameters to set somewhere? Or do I need a more recent kernel (like upgrading to CentOS 6?)
The docking is a Sharkoon Quickport Duo v2 + 2 drives + 1 eSATA cable... http://www.sharkoon.com/?q=en/content/sata-quickport-duo-v2 The eSATA controller is an HighPpoint PciE 2 ports combo eSATA/USB with (supposedly) port-multiplier support Apparently based on an Silicon image Sil 3132 Seems like the port multiplier part does not work correctly...
kernel: ata7: SATA link up 1.5 Gbps (SStatus 113 SControl 10) kernel: ata7.15: Port Multiplier 1.1, 0x197b:0x2352 r0, 2 ports, feat 0x0/0x0 kernel: ata7.15: Asynchronous notification not supported, hotplug won't kernel: work on fan-out ports. Use warm-plug instead. kernel: ata7.00: hard resetting link
The logs are full of "hard resetting link", "softreset failed" and other "failed to reset PMP, giving up"
I did not try to reboot yet... Would be a pain to have to reboot every time I need to plug drives. :/
I am not the only one... http://linux.derkeiler.com/Mailing-Lists/SuSE/2011-10/msg00055.html He has a kernel 2.6.37.6-0.7 and it still fails so I am wondering if upgrading to CentOS 6.x would help at all...
Thx, JD
