Greetings all,
This patch adds T10/SCSI WWN / Extended Vital Production Desciptor pages
(EVPD) information into Target_Core_Mod/ConfigFS. These ConfigFS
attributs are defined as READ-WRITE, but currently only implement
READ-ONLY and return -ENOSYS (this will be changing soon).
This patch adds the following INQUIRY EVPD=1 protocol information to
ConfigFS:
*) Protocol Identifier
*) Association
*) Identifier Type
*) Identifier Binary, ASCII, and UTF-8 encoding
This patch is made against lio-core-2.6.git/master
and tested on v2.6.28. The lio-core-2.6.git tree can be found at:
http://git.kernel.org/?p=linux/kernel/git/nab/lio-core-2.6.git;a=summary
Here is what the layout looks like with some Parallel SCSI (pscsi_1/sdb)
and Serial SCSI (pscsi_2/sdc and pscsi_2/sdd):
