The latest os-brick switched how some of this device discovery is done to use lsscsi as a much faster and more efficient way of finding it.\n\nThe down side to this is the previous package, sg_scan, was available by default on all our nodes, but lsscsi isn\u0027t. It is packaged for all of our supported platforms, just not pulled in already by any of our other packages that are there by default.\n\nSo this just makes sure when it comes time for nova to call into os-brick, the expected utility will be available. Since doing a \"pip install os-brick\" won\u0027t process os-brick\u0027s bindep file, we need to call it out here.","commit_id":"b3b56d8127c8488ad0c7c0095b056b23dde1e96d"}]}
