Reset HBA port in Oracle Solaris

If the devices not immediately available in fabric zones in a storage area network you can reinitialize the link to the devices by using the luxadm -e forcelip command.

The following command can be used to list HBA devices:

[root @ unixonline]
/ # luxadm -e port
/devices/pci@1c,600000/QLGC,qlc@1/fp@0,0:devctl                     CONNECTED
/devices/pci@1c,600000/QLGC,qlc@1,1/fp@0,0:devctl                   CONNECTED

The following command can be used to reset storage interconnects:

NOTICE: Do not try this in critical servers unless you are confident that multipathing is correctly configured.

[root @ unixonline]
/ # luxadm -e forcelip /devices/pci@1c,600000/QLGC,qlc@1/fp@0,0:devctl

forcelip command is reinitialize the link to the fabric-connected devices.

The forcelip command can be issued to the controller names(OS Device Name) as well:
