This function can allocate a new pdu using a specific itt value and specific flags instead of using the defaults of, next iff, no flags set. This can be used when we need to allocate additional PDUs in a chain, for commands that span across multiple PDUs and where all need to keep the same itt value. For example ->WRITE10 cdb ->DATAOUT -<RESPONSE Here the DATAOUT PDU belongs to the same task that was started by write10 so it need to use the same itt value.
Libiscsi is a clientside library to implement the iSCSI protocol that can be used to access resource of an iSCSI Target. The library is fully async with regards to iscsi commands and scsi tasks, but a sync layer is also provided for ease of use for simpler applications. The src directory contain a handful of useful iscsi utilities such as logging in to and enumerating all targets on a portal and all devices of a target. The examples directory contain example implementation of how to access both the sync and acync api of libiscsi. Libiscsi is a work in progress. It aims to become a full async library for iscsi functionality, including all features required to establish and maintain a iscsi session, as well as a low level scsi library to create scsi cdb's and parse/unmarshall data-in structures. Installation ============ ./autogen.sh ./configure make sudo make install Build RPM ========= To build RPMs run the following script from the libiscsi root directory ./packaging/RPM/makerpms.sh
