https://bugzilla.redhat.com/show_bug.cgi?id=1171933 Adjust the processLU error returns to be a bit more logical. Currently, the calling code cannot determine the difference between a non disk/lun volume and a processed/found disk/lun. It can also not differentiate between perhaps real/fatal error and one that won't necessarily stop the code from finding other volumes. After this patch virStorageBackendSCSIFindLUsInternal will stop processing as soon as a "fatal" message occurs rather than continuting processing for no apparent reason. It will also only set the *found value when at least one of the processLU's was successful. With the failed return, if the reason for the stop was that the pool target path did not exist, was /dev, was /dev/, or did not start with /dev, then iSCSI pool startup and refresh will fail.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
