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): /sys/kernel/config `-- target |-- core | |-- pscsi_1 | | |-- hba_info | | `-- sdb | | |-- attrib | | | |-- hw_max_sectors | | | |-- hw_queue_depth | | | |-- max_sectors | | | |-- queue_depth | | | |-- status_thread | | | |-- status_thread_tur | | | `-- task_timeout | | |-- control | | |-- enable | | |-- fd | | |-- info | | `-- wwn | | |-- evpd_assoc_logical_unit | | |-- evpd_assoc_scsi_target_device | | |-- evpd_assoc_target_port | | |-- evpd_protocol_identifier | | `-- evpd_unit_serial | |-- pscsi_2 | | |-- hba_info | | |-- sdc | | | |-- attrib | | | | |-- hw_max_sectors | | | | |-- hw_queue_depth | | | | |-- max_sectors | | | | |-- queue_depth | | | | |-- status_thread | | | | |-- status_thread_tur | | | | `-- task_timeout | | | |-- control | | | |-- enable | | | |-- fd | | | |-- info | | | `-- wwn | | | |-- evpd_assoc_logical_unit | | | |-- evpd_assoc_scsi_target_device | | | |-- evpd_assoc_target_port | | | |-- evpd_protocol_identifier | | | `-- evpd_unit_serial | | `-- sdd | | |-- attrib | | | |-- hw_max_sectors | | | |-- hw_queue_depth | | | |-- max_sectors | | | |-- queue_depth | | | |-- status_thread | | | |-- status_thread_tur | | | `-- task_timeout | | |-- control | | |-- enable | | |-- fd | | |-- info | | `-- wwn | | |-- evpd_assoc_logical_unit | | |-- evpd_assoc_scsi_target_device | | |-- evpd_assoc_target_port | | |-- evpd_protocol_identifier | | `-- evpd_unit_serial <SNIP> >From the Parallel SCSI device at pscsi_1/sdb: target-core:/sys/kernel/config/target/core/pscsi_1/sdb/wwn# cat * T10 EVPD Identifier Association: addressed logical unit T10 EVPD Identifier Type: EUI-64 based T10 EVPD Binary Device Identifier: 20010b9fe9f4b0200 T10 EVPD Identifier Association: addressed logical unit T10 EVPD Identifier Type: T10 Vendor ID based T10 EVPD ASCII Device Identifier: MAXTOR C40464HK T10 EVPD Unit Serial Number:: C40464HK >From the Serial SCSI device at pscsi_2/sdd: target-core:/sys/kernel/config/target/core/pscsi_2/sdd/wwn# cat * T10 EVPD Identifier Association: addressed logical unit T10 EVPD Identifier Type: NAA T10 EVPD Binary Device Identifier: 350010b90000292df T10 EVPD Identifier Association: SCSI target device T10 EVPD Identifier Type: SCSI name string T10 EVPD UTF-8 Device Identifier: naa.50010B90000292DC T10 EVPD Identifier Association: target port T10 EVPD Identifier Type: NAA T10 EVPD Binary Device Identifier: 350010b90000292de T10 EVPD Identifier Association: target port T10 EVPD Identifier Type: Relative target port identifier T10 EVPD Binary Device Identifier: 400000002 T10 EVPD Protocol Identifier: SAS Serial SCSI Protocol T10 EVPD Protocol Identifier: SAS Serial SCSI Protocol T10 EVPD Unit Serial Number:: E20HY72K Comments..? --nab [PATCH 1/2] [Target_Core_Mod]: Move 10_wwn_t to se_subsystem_dev_t->t10_wwn [PATCH 2/2] [Target_Core_Mod/ConfigFS]: Add T10 EVPD / WWN storage object attributes drivers/lio-core/target_core_base.h | 6 +- drivers/lio-core/target_core_configfs.c | 212 +++++++++++++++++++++++++++++- drivers/lio-core/target_core_device.c | 8 +- drivers/lio-core/target_core_mib.c | 30 ++-- drivers/lio-core/target_core_seobj.c | 2 +- drivers/lio-core/target_core_transport.c | 19 ++- drivers/lio-core/target_core_transport.h | 4 + 7 files changed, 251 insertions(+), 30 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
