Basically the situation is, I have a box running Debian, the box internally has an Intel SCSI RAID controller which is controlling 2 hard drives in RAID1 mode which is where the OS is installed.
Further, I have a QLogic fiber channel adapter that connects the unit to a Fiber Channel SAN.
My process of installation is I'll install Debian to the local drives, and leave the QLogic firmware out of it for the time being.
Then once I get the unit online, I'll install the firmware drivers.
This flops my internal drives from /dev/sda to /dev/sdc, which is a bit annoying, but recoverable. Probably should address these by UUID anyways.
Once I get back online, I have to install multipath-tools (the framework is a multipath framework).
However, once I reboot the machine again, it fails on boot after discovering multipath targets, saying my local drives are busy and cannot be mounted to /root.
Any help in what may be the problem here? Or at least how to disable multipath until after the unit boots and then ignores the internal drives?
