commit b72790bacfd356021b2dd870ade6c9c216fd14a0 Author: Lucian Petrut <lpet...@cloudbasesolutions.com> Date: Fri Nov 20 16:20:40 2015 +0200 iSCSI initiator refactoring using iscsidsc.dll This patch adds a new iscsi initiator utils class, leveraging iscsidsc.dll functions. The advantages are: * Same error output as iscsicli, without the proccess spawn overhead * Improved overall performance, having finer control over the iSCSI initiator and avoiding unnecessary operations * Fixed bugs related to LUN discovery * Static targets are used instead of having portal discovery sessions. This will let us use backends that require discovery credentials (which may be different than the credentials used when logging in targets) * improved MPIO support (the caller must request logging in the target for each of the available portals. Logging in multiple targets exporting the same LUN is also supported). Also, a specific initiator can be requested when creating sessions.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1372827 Title: Improve efficiency of Hyper-V attaching iSCSI volumes Status in OpenStack Compute (nova): Triaged Status in os-win: Fix Released Bug description: The Hyper-V driver in Nova is not very efficient attaching Cinder volumes to the VMs. It always tries to refresh the entire connection to the iSCSI target: https://github.com/openstack/nova/blob/master/nova/virt/hyperv/volumeutilsv2.py#L87 This is a time consuming task that also blocks additional calls during this time. The class should be refactored to work in a more efficient way. Calling the 'Update' method everytime a volume is attached should be replaced by a more intelligent mechanism. As reported in https://bugs.launchpad.net/nova/+bug/1372823 a call to 'self._conn_storage.query("SELECT * FROM MSFT_iSCSISessionToDisk")' could help.
