[우분투] 인피니밴드 인터페이스 이름 변경

1. IPoIB 인터페이스 하드웨어 주소 확인

ip a | grep ib

밑줄 친 부분이 설정 파일 중 address에 해당하는 부분

 

2. 설정 파일 (/etc/udev/rules.d/70-persistent-ipoib.rules) 수정

# This is a sample udev rules file that demonstrates how to get udev to
# set the name of IPoIB interfaces to whatever you wish.  There is a
# 16 character limit on network device names.
#
# Important items to note: ATTR{type}=="32" is IPoIB interfaces, and the
# ATTR{address} match must start with ?* and only reference the last 8
# bytes of the address or else the address might not match the variable QPN
# portion.
#
# Modern udev is case sensitive and all addresses need to be in lower case.
#
ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="32", ATTR{address}=="?*08:c0:eb:03:00:7c:88:86", NAME="ib1"
ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="32", ATTR{address}=="?*08:c0:eb:03:00:7c:88:87", NAME="ib2"

 

3. 재부팅

sudo reboot

 

4. 잘 적용됐는지 확인

ip a | grep ib

ib1, ib2로 잘 변경되었음
