Creating Fibre Channel connectivity
Two or more storage systems enabled for Fibre Channel must be added to a management group
to use Fibre Channel connectivity. A 10 GbE network connection is required.
Zoning
Configure the Fibre Channel zoning after the storage systems are added to a management group
if zoning by WWPNs. The WWNNs and WWPNs are assigned when the Fibre Channel-enabled
storage systems are added to a management group. The WWPNs are derived from these WWNNs.
If storage systems are removed from the management group for maintenance, they retain the same
WWNNs and WWPNs when they are returned to that management group.
NOTE:
The WWNNs and WWPNs are assigned to the management group. If the management
group is deleted and the Fibre Channel-enabled storage systems are added to a different
management group, their WWNNs and WWPNs will change.
Using MPIO with Fibre Channel
MPIO is required with HP StoreVirtual Storage Fibre Channel. Install the Microsoft MPIO on the
Fibre Channel host before assigning Fibre Channel volumes to servers. After installing Microsoft
MPIO, add the Device Hardware ID for HP LeftHand.
Adding the MPIO Device Hardware ID
1.
Open MPIO on the Fibre Channel host.
2.
Click Add on the MPIO Devices tab of the MPIO Properties application.
3.
Enter LEFTHANDP4000 disk in the Add MPIO Support dialog box.
4.
Click OK to close the dialog box.
5.
Click OK again to close MPIO Properties.
