Description of problem:
I've created following partitions during installation, having /mnt/data mount point as the only partition on a FCP LUN (/dev/sda):

[root@rtt7 ~]# lsblk 
NAME     MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda        8:0    0    8G  0 disk 
└─sda1     8:1    0    3G  0 part /mnt/data
dasda     94:0    0  2.3G  0 disk 
└─dasda1  94:1    0  2.1G  0 part /
dasdb     94:4    0  2.3G  0 disk 
└─dasdb1  94:5    0  500M  0 part /boot
dasdc     94:8    0  2.3G  0 disk 
└─dasdc1  94:9    0  600M  0 part [SWAP]
[root@rtt7 ~]#

The FCP disk has device number a007, WWPN 0x500507630500c73d and LUN 0x4020400700000000

After reboot, system fails to boot, because the FCP device backing /mnt/data is not freed from the cio_ignore list and brought online:

[root@rtt7 ~]# cat /proc/cio_ignore
0.0.0000-0.0.0008  
0.0.000a-0.0.09ff  
0.0.0a03-0.0.3526  
0.0.3528-0.0.3626  
0.0.3628-0.0.3726  
0.0.3728-0.0.ffff  
0.1.0000-0.1.ffff  
0.2.0000-0.2.ffff  
0.3.0000-0.3.ffff  
[root@rtt7 ~]# 

Version-Release number of selected component (if applicable):
anaconda-19.31.122-1.el7
python-blivet-0.61.0.25-1.el7

How reproducible:
always

Steps to Reproduce:
1. start installation with DASD/FCP devices defined on the kernel command line
2. create partitioning where data mount point (/mnt/data) is the only mount point on a FCP LUN
3. reboot to installed system

Actual results:
system fails to boot, /mnt/data cannot be mounted

Expected results:
system boots without errors

Additional info:
* /etc/zfcp.conf was not created during the installation

Workaround:
1) enter root password to enter emergency mode
2) add a record to /etc/zfcp.conf for every FCP LUN with data (non-system) mount point:
echo "0.0.a007 0x500507630500c73d 0x4020400700000000" >> /etc/zfcp.conf
3) reboot
