Hi,
recently I changed my storage controllers to two DELL PERC H310 controllers which are modified to IT described above.
I have had some issues with my mvsas based controllers, a faulty drive and a second with a bad sata connector so my old array crashed.
Now I started with a new array, by now with 4 discs online and copy my data to the array, then preclear a disc, add it to the array, copy again and so on.
While copying I'm getting minimal I/O errors on different discs. All drives pass a long SMART test, some are some month old, other a year or two so I can't believe I have that much faulty drives in my system. SAS cables are new to ensure not to be the source of my problems.
Are there any know issues with the H310 controllers? I'm unsure what will happen if the error happens on a assigned drive.
