Chelsio T520 T420安装LIO iSCSI Target Offload

Posted 2022-01-28 niezhongle

安装lio_target需要特殊组件,先配置kernel，再安装lio_target

  #配置kernel

  rpm -ivh kernel-3.10.0-862.2.3.el7.src.rpm(忽略此次报错)

  cd /root/rpmbuild/SPECS/

  rpmbuild -bp kernel.spec --nodeps

  cd  ../BUILD/kernel-3.10.0-862.2.3.el7/linux-3.10.0-862.2.3.el7.x86_64/

  make prepare

  cp -r  ../linux-3.10.0-862.2.3.el7.x86_64  /usr/src

  #安装lio_target

  cd  ChelsioUwire-3.9.0.0

  make lio_install KSRC="/usr/src/linux-3.10.0-862.2.3.el7.x86_64/" KOBJ="/lib/modules/3.10.0-862.el7.x86_64/build/"
