Extended Fabrics device limitations
Extended Fabrics is normally not implemented on the following device:
•
The HP StorageWorks B-Series iSCSI Director Blade has eight Gigabit Ethernet ports and eight FC
ports. It is used to implement the iSCSI Gateway Service. The Gigabit Ethernet ports are used to
connect iSCSI initiators, and the FC ports are used to connect to any device.
Configuring an extended ISL
Before configuring an extended ISL, ensure that the following conditions are met:
•
Be sure that the ports on both ends of the ISL are operating at the same port speed, and can be
configured at the same distance level without compromising local switch performance.
NOTE:
A long-distance link also can be configured to be part of a trunk group. Two or more
long-distance links in a port group form a trunk group when they are configured for the same speed, the
same distance level, and their link distances are nearly equal. For information on trunking concepts and
configurations, see Chapter 20, ”
Administering ISL trunking
” on page 435.
•
Use only qualified HP B-Series SFPs. These are the only SFPs supported on the 8Gb products.
1.
Connect to the switch and log in using an account assigned to the admin role.
2.
Enter the
switchDisable
command.
3.
Enter the
configure
command to set the switch fabric-wide configurations. You can set the following
fabric-wide settings (* = multiplication symbol):
4.
Enter the
portCfgLongDistance
command, using the following syntax:
portcfglongdistance [slotnumber/]portnumber [distance_level]
[vc_translation_link_init] [desired_distance]
