Python isVirtualDevice Examples

Example #1

File: iscsi.py Project: rollandf/vdsm

def findUnderlyingStorage(devPath):
    # make sure device exists and is accessible
    os.stat(devPath)
    sessions = []
    try:
        devs = devicemapper.getSlaves(os.path.basename(devPath))
    except:
        devs = [os.path.basename(devPath)]

    for realDev in devs:
        if not devicemapper.isVirtualDevice(realDev):
            sessions.append(getiScsiSession(realDev))
            continue

        for slave in devicemapper.getSlaves(realDev):
            sessions.extend(findUnderlyingStorage(os.path.join("/dev", slave)))

    return sessions

Example #2

File: devicemapper_test.py Project: kumarchandan786/vdsm

def test_is_virtual_device(zero_dm_device):
    dm_id = devicemapper.getDmId(zero_dm_device)
    assert devicemapper.isVirtualDevice(dm_id)
