Add these settings to the iscsi context structure and initialize them to sane valued. When sending login commands to the target, use these values instead of hardcoded values. Parse when the target sends a login reply back to us and update these variables if the target asks us to. This allows us to detect when our defaults are too big for the target and adjust the settings we use so we match the target. Some targets have a very small accepted default for some settings. During login, we will initially send these keys with our dafult values. These targets will then respond back by refusing to transition to the next login phase, and by telling us back what the maximum of these values should be. In this case we have to try the login again but use the smaller values we got from the target. Othervise, if we try again, ignoring the value from the target, and just repeat using our defaults the target will abort the login with a "initiator error".
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
