[dm-devel] latest multipath-tools from git breaks EMC CX

[Lars Marowsky-Bree]

More specifically, it fails to detect the vendor correctly, and uses the
most basic internal defaults:

...
===== path sdz =====
bus = 0
dev_t = 65:144
size = 280278656
path checker = readsector0 (internal default)
#
# all paths :
#
#:#:#:# sdaa 65:160  []
#:#:#:# sdab 65:176  []
#:#:#:# sdac 65:192  []
#:#:#:# sdad 65:208  []
#:#:#:# sdae 65:224  []
#:#:#:# sdaf 65:240  []
#:#:#:# sdag 66:0    []
#:#:#:# sdah 66:16   []
