===========System Design===========
Server A --> 2 PCI LSI HBA Cards
Server B --> 2 PCI LSI HBA Cards
8 x SAS Disk Shelf --> Dual SAS Controller 12 Slot Disk Shelf
96 Disks all SAS Seagate Enterprise Drives
Systems are cabled in redundant fashion through both HBA Cards and both Server A and B can see all of the disks in the shelf 2 times in "lsblk" (dual port)
Systems are running identical CentOS 7 (soon to be 8)
Server A handles 48 disks and has a file system on it, well call this file system FS-A. Server B handles 48 disks and has a file system on it, well call this file system FS-B.
This is setup this way to provide a high availability solution in the event Server A or Server B hardware fails the other can mount its file system and present it.
===========Question===========
Assuming Server A is handling FS-A and Sever B is handling FS-B are we able to utilize multipath connections to the drives on the respective servers holding the file system? I am concerned the second port of the drive is already consumed by the presence on the alternate server.
