I Cannot seem to get my installation working with HBA mode, on installation complete it shows al the disk drives with a disk prepare failure.
When i SSH into one of the machines and execute fdisk -l it shows duplicate disk drives beginning with /dev/mapper/mpath (in the web interface it has for example sdb and sdc with the same serial number), also when i try to manually add the disk drives it just doesn't work. Does anyone have had this problem before or knows how to solve?
I tried to manually remove the /dev/mapper paths and used the following commands:
wipefs --all /dev/sdXX
dd if=/dev/zero of=/dev/sdXX bs=1M count=20 oflag=direct,dsync
Kind regards

Use regular lvm commands to delete old/unused lvm volumes
If these disks were used on FreeBSD or FreeNAS, it could be better to zero the first and last 1G Bytes on the disk

I think i found the problem, we have a DL360 Gen9 connected to a D3700 storage enclosure but we connected P1 on IO A & B so it has dual port connection. Isn't this supported in PetaSAN? I now have a single cable from the H241 to the D3700 and it comes up with single drives.
