SCSI devices can return a QUEUE BUSY indicator, so having a RAID controller do something similar doesn't sound unusual. But the driver needs to returns translate that into a QUEUE BUSY so that the SCSI midlayer can handle it correctly. It might make sense to take this to linux-scsi with the driver maintainer in Cc. |
