[dm-devel] [PATCH] IBM hwtable update

[lbt]

I think FAILBACK_IMMEDIATE for DS6000 makes more sense. Also for SVC (2145)
the same settings should be used as DS6000 since it is also an asymetric
device,
i.e.
    r += store_hwe_ext(hw, "IBM", "2145", GROUP_BY_PRIO, DEFAULT_GETUID,
                 "/sbin/mpath_prio_alua /dev/%n", "0", "1 queue_if_no_path",
"tur", FAILBACK_IMMEDIATE);
