[dm-devel] [PATCH] multipath-tools: add Pure Storage device to hardware table

[Menny_Hamburger at dell.com]

If driver names are different between tophat and magichat you can stick with different names instead of an alias in modprobe.conf and do "install x modprobe install y" in modprobe.conf

Please DROP this one. It was already included by Brian Bunker <brian at purestorage.com>

Though it's a bit different. Why ?

+               .vendor        = "PURE",
+               .product       = "FlashArray",
+               .features      = DEFAULT_FEATURES,
+               .hwhandler     = DEFAULT_HWHANDLER,
+               .selector      = "queue-length 0",
+               .pgpolicy      = MULTIBUS,
+               .pgfailback    = -FAILBACK_IMMEDIATE,
+               .checker_name  = TUR,
+               .fast_io_fail  = 10,
+               .user_friendly_names = USER_FRIENDLY_NAMES_OFF,
+               .prio_name     = DEFAULT_PRIO,
+               .no_path_retry = 0,
+               .dev_loss      = 60,
+               .prio_args     = NULL,
