Description John Pittman 2017-03-09 20:44:31 UTC
Created attachment 1261696 [details]
patch editing multipath.conf.defaults and hwtable.c

Description of problem:

There are 6 different listings for the Dell 3xxxxx family in the hardware table, and they all have the same settings.  These should be combined using regex in .product line.  This will provide ease of use/viewing in multipath.conf.defaults, multipath.conf,  hwtable.c, and the 'multipath -t' command.

Version-Release number of selected component (if applicable):


How reproducible:

Run 'multipath -t' and observe Dell 3xxxxx hardware table defaults.

Actual results:

6 separate listings

Expected results:

1 listing

Comment 2 Ben Marzinski 2017-03-10 20:13:44 UTC
I don't see a problem with this. However, upstream has already combined them (and some additional devices) into three configs (still identical) based on devices that share the same firmware. I'll ask upstream if anyone objects to combining them further, and I'll pull whatever the upstream result is back into RHEL.

Comment 5 Ben Marzinski 2017-04-25 21:12:46 UTC
Nobody upstream objected to combining them, so I'm fine it. I've also updated the config to use the upstream no_path_retry value (30 checks instead of 15), and changed the product regex to allow the MD38xxx devices as well.
