Solution 1598165.1 : How to Offline/Online a Fibre Channel (FC) HBA Port

Applies to:

SPARC T4-1B
Solaris Operating System - Version 8 6/00 U1 to 10 1/13 U11 [Release 8.0 to 10.0]
Information in this document applies to any platform.

Goal

How can a fc hba port be taken offline?

Solution

luxadm command can be used to offline a fc hba port.

Solaris 10 SPARC (see x86 procedure below)

First get the device path by running luxadm -e port command

example:

luxadm -e port

Found path to 3 HBA ports
/devices/pci@8,600000/SUNW,qlc@2/fp@0,0:devctl CONNECTED
/devices/pci@9,600000/SUNW,qlc@1/fp@0,0:devctl CONNECTED
/devices/pci@9,600000/SUNW,qlc@2/fp@0,0:devctl NOT CONNECTED <<<

Then run luxadm -e offline/online command, AND leave last "/" and after off path.

For example in this case remove "/fp@0,0:devctl" from path used for command see below.

example

luxadm -e offline /devices/pci@9,600000/SUNW,qlc@2
luxadm -e online /devices/pci@9,600000/SUNW,qlc@2

Solaris 10 x86

First get the device path by running luxadm -e port command

example:

luxadm -e port

Only modify "online" path used in command, see below.

NOTE: "online" will occur on both ports of a dual port hba. If other (ie working) port is in use it may cause a issue, so proceed with caution.

example

luxadm -e offline /devices/pci@0,0/pci10de,377@a/pci1077,171@0
luxadm -e online /devices/pci@0,0/pci10de,377@a
