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

Hi Christophe, Hannes,

I thought I had already sent parts of these but they don't seem to be in 
the git head when
I look now. I'd suggest a small change for the DS6000 aka 1750500. Since 
paths with
higher prio are more appreciated, wouldn'T FAILBACK_IMMEDIATE make more 
sense?

Regards,
Stefan

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);
