Hi, I got a report about strange behaviour of "multipath -l" if one of the devices that are used for multipathing is set offline. In that case the code in libmultipath (discovery.c) just ends processing and the output is incomplete. The problem is that setting a scsi device offline (through sysfs state attribute) will remove the device node in /dev. And this will cause pathinfo to abort which gives no output at all. This looks strange and in that situation the path could be assumed as failed. On the other hand if the device node just had been removed "failed" wouldn't be a correct state. One solution might be to use the state attribute of the scsi device (wasn't that once called online? *sigh*) to check for an offline device and set the path state to failed in that case. Or should the map get updated as soon as the device is set offline, to remove the path?
