The drive is disqualified unless your usecase can tolerate the possibly
very high error recovery time for these drives.

Do a search for Red Hat documentation on the SCSI Command Timer. By default
this is 30 seconds. You'll have to raise this to 120 out maybe even 180
depending on the maximum time the drive attempts to recover. The SCSI
Command Timer is a kernel seeing per block device. Basically it's giving
up, and resetting the link to drive because while the drive is in deep
recovery it doesn't respond to anything.
