The legacy and newer QLogic guides disagree about the default driver, supported adapters, NPIV, sysfs layout and module lifecycle. The HOWTO also carries SVN, kernel replacement, firmware flashing and discovery commands that can disrupt active storage. Commit7aade0a109("Makefile: Make the qla2x00t-32gbit driver the default QLogic FC driver") selected the newer tree by default. Commita788a4efd7("Newer version of QLogic target driver with 16G (26xx/83xx) support") added that tree and disabled legacy NPIV target callbacks. Commit08e532715d("Remove procfs support") removed the old management path. Use each qla2xxx_pci_tbl[] and qla_os.c for hardware and firmware facts. Document QLA_32GBIT=no, current per-port sysfs state, reset effects and the matched qla2xxx_scst and qla2x00tgt modules. Replace unsafe generic recipes with repository or vendor sources and mark every HBA, fabric, target and backing-device operation as live.
Overview
This is the source code repository of the SCST project. SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes:
- The SCST core in the scst/ subdirectory.
- A tool for loading, saving and modifying the SCST configuration in directory scstadmin/.
- Several SCSI target drivers in the directories iscsi-scst/, qla2x00t-32gbit/, qla2x00t/, srpt/, scst_local/ and fcst/.
- User space programs in the usr/ subdirectory, e.g. fileio_tgt.
- Various documentation in the doc/ subdirectory.
Instructions for building and installing SCST are available in the INSTALL.md file.
QLogic target driver
Two QLogic target drivers are included in the SCST project.
The default driver is located in the qla2x00t-32gbit directory. It is the newer one.
May anyone wish to switch back to the older driver that only supported up to
16 Gb/s adapters, it is located in qla2x00t directory. To make use of the
older driver build scst with environment variable QLA_32GBIT=no set.
