Remove these callback functions because: - Since the introduction of the 'active' attribute, these callback functions are no longer essential. See also commit9d21169f8c("scst: implement BLOCKIO devices "active" attribute"). - The current implementation may break I/O. The following ALUA configuration is sufficient to break I/O (because a remote group with state 'standby' occurs last): DEVICE_GROUP dgroup1 { DEVICE disk01 TARGET_GROUP tgroup1 { group_id 256 preferred 1 state active TARGET scst_local_tgt } TARGET_GROUP tgroup2 { group_id 257 state standby TARGET scst_local_tgt_remote { rel_tgt_id 7 } } } See also commit2b202209ca("ALUA DRBD compatibility"). git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@8912 d57e44dd-8a1f-0410-8b47-8ef2f437770f
Overview ======== This is the SCST development repository. It contains not a single project SCST as one can think, but a number of them, which are divided as the following: 1. SCST core in scst/ subdirectory 2. Administration utility for SCST core scstadmin in scstadmin/ 3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc. 4. User space programs in usr/ subdirectory, like fileio_tgt. 5. Some various docs in doc/ subdirectory. Those subprojects are in most cases independent from each other, although some of them depend from the SCST core. They put in the single repository only to simplify their development, they are released independently. Thus, use "make all" only if you really need to build everything. Otherwise build only what you need, like for iSCSI-SCST: make scst scst_install iscsi iscsi_install For more information about each subproject see their README files. QLogic target driver ==================== The QLogic target driver qla2x00t is the old driver, forked from qla2xxx several years ago. It is very stable, well tested and actively used in many production setups. There is also a new driver that supports 32 Gb/s FC in the qla2x00t-32gbit directory. That driver has not yet reached the same maturity level as the old qla2x00t driver. Vladislav Bolkhovitin <vst@vlnb.net>, http://scst.sourceforge.net
