Eric,
The "protocol specific logical unit mode page for SAS
SSP - short format" has a 'transport layer retries'
bit. I thought that SAS tape drives would implement
that mode page (0x18,0x0) and allow that bit to be
changeable.

The "special scsi opcode to enable TLR" seems to imply
another technique.
