Which Linux kernel supports dynamic LUN scanning?
A.
2.3
B.
2.4
C.
2.5
D.
2.6
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.
