Make certain the kernel command timer value is greater than the driver

the entire array. It really is a terrible default.
Are nearline SAS drives considered consumer drives?
If it's a SAS drive, then no, especially when you start talking about
things marketed as 'nearline'. Additionally, SCT ERC is entirely a SATA
thing, I forget what the equivalent in SCSI (and by extension SAS) terms
is, but I'm pretty sure that the kernel handles things differently there.
