Return to scsi_all.h CVS log

Up to [local] / src / sys / scsi

Add one more 1 byte (reserved, as defined in spc-2) field to the
scsi_inquiry_data structure.

The last commit made the structure 57 bytes long, an odd number. This
caused problems with at least two drivers, which were not prepared to
handle the IGNORE WIDE RESIDUE message during probing. This message
apparently being generated during probes of non-existant LUNs.

Problem found on siop by Rev. Chris Cappuccio and on iha by Andreas
Gunnarsson <andreas@zzlevo.net>.
