Confirming storage connectivity for SGI in a fibre-channel arbitrated loop topology
This section contains an example of an arbitrated loop connection with the
fibre-channel adapter cards. The following conditions apply to this example:
v The PCI-FC-1P-OPT adapter cards are on PCI busses 6 and 8.
v There are four LUNs defined on the storage unit.
v Each host adapter is connected to a host adapter in the storage unit.
v Each host adapter maintains two instances of each LUN.
