Emulex Drivers for Linux User Guide
Appendix F: ARM Support
Emulex HBAs support ARM servers. This appendix describes information pertaining to ARM support.
The following inbox Linux operating system distributions are the minimum versions supported on ARM servers:
 Oracle UEK 5
 XenServer Citrix 7.4
 XenServer Citrix 8.0
 SLES 12 SP4
 SLES 15
 RHEL and CentOS 7.6
 RHEL and CentOS 8.0
 OEL 7.7
 OEL 8.0
 Debian, Ubuntu, National Univ Kylin 16.0.4, 18.0.4, 20.04
 Deepin UnionTech UOS 16.0.4, 18.0.4, 20.04
The only Emulex utility supported on ARM servers is the Emulex HBA Capture utility.
To update firmware, use the Linux sysfs command. Refer to the section on updating firmware in the Emulex Drivers for
Linux User Guide for details.
To configure driver parameters, use one of the following Linux tools. Refer to the sections that describe FC driver parameters
and how to configure them in the Emulex Drivers for Linux User Guide.
 The modprobe command for temporary configuration.
 The elx-lpfc.conf file for persistent configuration.
 The sysfs interface (to view and modify parameters after loading the FC driver).
To create a vPort for NPIV, use the SCSI transport device /sys/class/fc_host/<hostx>/vport_create attribute,
where <hostx> is the HBA. Echo a string formatted as <wwpn>:<wwnn>, where <wwpn> and <wwnn> are the WWPN and
WWNN for the vPort to be created. Do not include colons (:) when specifying the WWPN and WWNN.
For example:
echo 30000000c9111111:50000000c9111111 > /sys/class/fc_host/host5/vport_create
To remove a vPort for NPIV, use the SCSI transport device /sys/class/fc_host/<hostx>/vport_delete attribute.
For example:
echo 30000000c9111111:50000000c9111111 > /sys/class/fc_host/host5/vport_delete
BFS is not supported.
NVMe over FC is not supported.
