Should I use devices in
/dev/mpathdirectly ? -
When creating partitions on newly-added multipath devices, the system doesn't update those partition entries in
/dev/mpath. -
There are missing partition devices in
/dev/mpath:
# ls -al /dev/mpath*

lrwxrwxrwx 1 root root 8 Dec 3 19:19 mpath0p1 -> ../dm-51
lrwxrwxrwx 1 root root 8 Dec 3 19:19 mpath1 -> ../dm-26
lrwxrwxrwx 1 root root 8 Dec 3 19:19 mpath1p1 -> ../dm-59
