How does one interpret these messages?

I'm running 6.2-RELEASE-p5 amd64.  This machine has 20Gb RAM.  The  
mpt0 device is an LSI fibre channel card attached to an external RAID  
system.

mpt0: <Dual LSILogic FC7X04X 4Gb/s FC PCI-Express Adapter> port  
0xc800-0xc8ff mem 0xfe2fc000-0xfe2fffff,0xfe2e0000-0xfe2effff irq 16  
at device 0.0 on pci5
mpt0: [GIANT-LOCKED]
mpt0: MPI Version=1.5.10.0
mpt0: Port 0: LinkState: Failed
mpt0: External Bus Reset Detected
mpt0: Port 0x0: FC LinkEvent: LIP(f7,f7) (Loop Initialization)
mpt0: Device needs AL_PA
mpt0: Port 0: LinkState: Active
mpt0: Rescan Port: 0


These are the messages that cropped up in the syslog over the last  
few days:
