Hi,
I have configured multipath, well attempted to on CentOS7, all was fine until I rebooted the system and all my partitions had disappeared? I have this server in production so rebooting is difficult. When leaving the multipath.conf as default I have experienced the issue. In fact I did not make the alias changes to the multipath.conf until Friday morning before 13/10/2017 but I have not restarted the multipathd.
OK here is my config:
cd /dev/mapper
ll

OK so I rightly or wrongly read that to get multipath’s you have to create the partitions on the /dev/mapper/mpath*1 so that is what I did, as you can see from the output above I had a few issues creating these (perhaps because this was the wrong thing to do?) So what I read just said to run the command again and you will just end up with another partition, for example:
lrwxrwxrwx. 1 root root 8 Oct 12 10:25 mpathc1p1p1 → …/dm-18
While the system is up after using kpartx to hotadd the filesystems all works OK.
Now looking at the default config for multipath.conf by going into ‘multipathd -k’ and using the ‘show blacklist’ command “dm-” is blacklisted, so I have done the following changes to the multipath.conf:
blacklist_exceptions {
device {
vendor “HP”
product “P2000 G3 FC”
}
devnode “dm-”
}
Use user friendly names, instead of using WWIDs as names.
defaults {
user_friendly_names yes
find_multipaths yes
}

}
blacklist {

}
Now in the multipath.conf, there is a section for configuring multipaths, however the only relevant entry that I could see that I could possibly make here in the example is alias:
#multipaths {
multipath {
wwid 3600508b4000156d700012000000b0000
alias yellow
Do i need to change the alias to one of my multipaths for example, such as /dev/mapper/mpathc1p1p1 for example? But this doesn’t really make a lot of sense to me.
As far as I can tell/understand there is not an entry in the system to state that these paths shown here, should exist during the bootup process:

This turned my attention to the lvm.conf file where the RedHat docco states that if you are using multipath you should add the following entry to the lvm.conf under devices:
filter = [ “r/block/”, “r/disk/”, “r/sd./", "a/./” ]
I did this and updated the initramfs and it caused the system not to boot. Once I removed this from the initramfs the system booted, I believe this is reference to if you are booting from a multipath SAN 
if I show the blkid:

It shows entries from /dev/sdb1 through to /dev/sdi1 and also my paths, which looks messy due to using kpartx to bring them online. I then turned my attention to trying fstab but did not want to cause system instability so tried using mount first and as I suspected nothing mounts correctly as it is already mounted.

multipath -v2 command displays nothing.
I have updated my initramfs with:
dracut --force --add multipath --include /etc/multipath
What am I missing, everything I have read doesnt state that I have to do any more than I have done but yet when I reboot none of my partitions are there???
I am of course apprehensive about restarting multipath or rebooting the server. I cannot seem to find any relevant logging, the boot.log is empty and the /var/log/messages has no relevant information.
Here is the output of multipath -v3:
