Confirming storage connectivity
The following sections tell you how to confirm storage connectivity for the following
topologies:
v Switched fabric
v Arbitrated loop
Confirming storage connectivity for SGI in a switched-fabric topology
Confirming storage connectivity for SGI in a switched-fabric topology
This section contains an example of a switched fabric 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 There are two connections from the switch to two host adapters on the storage
unit.
v
The switch is not zoned. Therefore, each LUN is available on each host adapter
from each host bus adapter. This means that there are four instances of each
LUN for each adapter card.
