Which Linux kernel supports dynamic LUN scanning?

The correct answer is D. 2.6. Linux provides multiple mechanisms to rescan the SCSI bus and recognize SCSI devices exposed to the system. In the 2.4 kernel solutions, these mechanisms were generally disruptive to the I/O since the dynamic LUN scanning mechanisms were not consistent. With the 2.6 kernel…

Explanation

Linux provides multiple mechanisms to rescan the SCSI bus and recognize SCSI devices exposed to the system. In the 2.4 kernel solutions, these mechanisms were generally disruptive to the I/O since the dynamic LUN scanning mechanisms were not consistent. With the 2.6 kernel, significant improvements have been made and dynamic LUN scanning mechanisms are available. Linux currently lacks a kernel command that allows for a dynamic SCSI channel reconfiguration like drvconfig or ioscan.
