Can't mount a multipath LUN

I'm trying to mount a lun, it's visible in multipath -ll and I can see the multiple access to it with lsblk. I know screw up somewhere along the line because sda isn't visibly mounted in lsblk anymore and i can't find where. Thank you in advance. root@debian:~# multipath -ll mpathb (3600508b1001037383941424344450500) dm-0 HP,LOGICAL VOLUME size=68G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=1 status=active `- 3:0:0:0 sda 8:0 active ready running mpatha (3600601601ad126004652c478fd40e511) dm-1 DGC,VRAID size=500G features='1 queue_if_no_path' hwhandler='1 emc' wp=rw |-+- policy='service-time 0' prio=4 status=active | |- 2:0:0:0 sdb 8:16 active ready running | `- 4:0:1:0 sde 8:64 active ready running `-+- policy='service-time 0' prio=1 status=enabled |- 2:0:1:0 sdc 8:32 active ready running `- 4:0:0:0 sdd 8:48 active ready running root@debian:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 68.3G 0 disk ├─sda1 8:1 0 1007K 0 part ├─sda2 8:2 0 127M 0 part └─sda3 8:3 0 68.2G 0 part sdb 8:16 0 500G 0 disk ├─sdb1 8:17 0 244G 0 part └─sdb2 8:18 0 256G 0 part sdc 8:32 0 500G 0 disk ├─sdc1 8:33 0 244G 0 part └─sdc2 8:34 0 256G 0 part sdd 8:48 0 500G 0 disk ├─sdd1 8:49 0 244G 0 part └─sdd2 8:50 0 256G 0 part sde 8:64 0 500G 0 disk ├─sde1 8:65 0 244G 0 part └─sde2 8:66 0 256G 0 part sr0 11:0 1 1024M 0 rom
