Identify FC HBAs on a Linux server
Perform the following steps to identify the Fibre Channel HBAs on a Linux host.
Steps
-
Identify Fibre Channel WWNs to connect to the storage system by doing the following:
-
Open a terminal session.
-
Run the
ls –l /sys/class/fc_host command.
-
Run the
more /sys/class/fc_host/host?/port_name command and replace the
? with the host numbers that are supplied in the data output.
-
Record the WWN numeric name.
-
If the hosts are connected to the storage system using FC switches, implement zoning to isolate traffic for each HBA:
NOTE Skip this step if hosts are directly connected to the storage system.
-
Use the FC switch management interface to create a zone for each server HBA. Each zone must contain only one HBA WWN and all the storage port WWNs.
-
Repeat for each FC switch.
NOTE The
ME5 Series storage systems support single initiator/multiple target zones.
