[dm-devel] feature="1 queue_if_no_path" vs. no_path_retry=queue

[Oren Held]

Hi,

According to all docs I've read, and some code, the following settings seem to have the same effect:
1. Setting features = "1 queue_if_no_path"
2. Setting no_path_retry = "queue"

Now that's confusing, especially when having conflicting configuration, e.g., from hwtable.c:
                /* IBM DS4100 */
                .vendor        = "IBM",
                .product       = "1724",
                .features      = "1 queue_if_no_path",
                .no_path_retry = 300,

It's not clear enough what would be the resulting behavior of this configuration.

Did I get it right? Is there a reason for keeping the features = "1 queue_if_no_path" option available in multipath-tools?

Thanks

Regards
