>>> 0a:0e.0 RAID bus controller: Adaptec AAC-RAID

This doesn't really tells us which controller it is, try with

 lspci -s 0a:0e.0 -nn

In the kernel source one can then find drivers/scsi/aacraid/linit.h,
and since lsscsi says ICP, my guess it is one of theese below.
When we know which one, one can try to check for issues.

Well, you have to check the return status: echo $?

Then it seems the drive itself is ok.
