multipath configuration for VNXe 3200
Hi, I am very new to VNXe. I am truing to configure multipath.
At the moment my server connected to a FC fabric with 2 FC cables. This fabric is connected to SP A with 1 cable.
Server has 1 2 port Emulex LPe12000 FC adapter. Debian 8 is installed on the server.
Could somebody help me to debug this issue please ?
-------------------------------------
My multipath.conf:
defaults {
user_friendly_names yes
}
devices {
device {
vendor "DGC"
product ".*"
product_blacklist "LUNZ"
path_grouping_policy "group_by_prio"
path_checker "emc_clariion"
features "1 queue_if_no_path"
hardware_handler "1 emc"
prio "emc"
failback "immediate"
rr_weight "uniform"
no_path_retry 60
}
}
-------------------------------------

What I found out is that I coudn't boot if I was connectied even with 1 link to a FC fabric.
I added rootdelay=30 to kernel boot options and it started to work.
So for debian 8 just :
apt-get install multipath-tools multipath-tools-boot
Then add rootdelay=30 to kernel boot options and restart.
You don't even need to create multipath.conf ! !
Works for me.

I am worried about these message:

Is it because I am trying to change multipath for active devices ? Debian installed on this LUN.
Should I configure multipath during installation or something like that ?
Thanks.

added a new LUN and it is working fine. Pulled cables and it is working:
root@debian:/etc# multipath -ll
36006016080304000aca7995700f0e79e dm-0 DGC,VRAID
size=50G features='1 queue_if_no_path' hwhandler='1 emc' wp=rw
`-+- policy='service-time 0' prio=2 status=active
|- 0:0:0:1 sdb 8:16 active ready running
`- 11:0:0:1 sdd 8:48 active ready running
Somehow Multipath doesn't like when the LUN with the root partition is used.
