[dm-devel] [PATCH] IBM hwtable update

[Hannes Reinecke <hare suse de>]

Hi Christophe,

attached is a patch to update hwtable.c with some IBM Storage Servers.
Especially the DS6000 should be handled properly as it again has
asymmetric paths.

Cheers,

Hannes

Subject: Hardware entries for IBM Storage Servers

Several IBM Storage Servers (most notably the DS range) need
specific hardware entries. This patch adds hardware entries
for:

- IBM ESS F20 (aka Shark)
- IBM DS6000
- IBM DS8000
- IBM SVC
