Using RPM (recommended)

Note

Supported only on RHEL 7 and RHEL 8 for POWER9

Note

In a herarchical environment xCAT-openbmc-py must be installed on both Management and Service nodes. On Service node xCAT-openbmc-py can be installed directly by following instructions in Install xCAT-openbmc-py on MN, or xCAT-openbmc-py can be installed on Service node from Management node by following instructions in Install xCAT-openbmc-py on SN from MN

Install xCAT-openbmc-py on RHEL 8 MN

  1. Configure RHEL 8 EPEL repository

    yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

  2. Install xCAT-openbmc-py

    yum install xCAT-openbmc-py

Install xCAT-openbmc-py on RHEL 8 SN from MN

Attention

Instructions below assume Service node has access to the Internet.

  1. Choose one of the 2 methods below to complete the installation

Install on diskful SN using updatenode or rinstall

  1. Make the target repository directory on the MN:

    mkdir -p /install/post/otherpkgs/rhels8.5.0/ppc64le/epel/Packages

  2. Download the RHEL 8 EPEL rpm:

    wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm -O /install/post/otherpkgs/rhels8.5.0/ppc64le/epel/Packages/epel-release-latest-8.noarch.rpm

  3. Create a repository in that directory:

    cd /install/post/otherpkgs/rhels8.5.0/ppc64le/epel/Packages/
createrepo .

  4. Configure otherpkglist attribute of the osimage

    chdef -t osimage rhels8.5.0-ppc64le-install-service otherpkglist=/opt/xcat/share/xcat/install/rh/service.rhels8.ppc64le.otherpkgs.pkglist

  5. Add the following entries to the contents of /opt/xcat/share/xcat/install/rh/service.rhels8.ppc64le.otherpkgs.pkglist

    ...
#NEW_INSTALL_LIST#
epel/Packages/epel-release-latest-8
#NEW_INSTALL_LIST#
xcat/xcat-core/xCAT-openbmc-py

  6. If SN was initially installed without xCAT-openbmc-py package, updatenode can be used to install that package

    updatenode <SN> -S

  7. If this is a new SN installation

    rinstall <SN> osimage=rhels8.5.0-ppc64le-install-service

Install on diskless SN using rinstall

  1. Add EPEL online repository https://dl.fedoraproject.org/pub/epel/8/ppc64le to pkgdir attribute of existing diskless RHEL 8 service osimage:

    chdef -t osimage -o rhels8.5.0-ppc64le-netboot-service -p pkgdir=https://dl.fedoraproject.org/pub/epel/8/Everything/ppc64le

  2. Configure otherpkglist attribute of the osimage

    chdef -t osimage rhels8.5.0-ppc64le-netboot-service otherpkglist=/opt/xcat/share/xcat/install/rh/service.rhels8.ppc64le.otherpkgs.pkglist

  3. Add the following entries to the contents of /opt/xcat/share/xcat/install/rh/service.rhels8.ppc64le.otherpkgs.pkglist

    ...
#NEW_INSTALL_LIST#
xcat/xcat-core/xCAT-openbmc-py

  4. Install diskless SN

    genimage rhels8.5.0-ppc64le-netboot-service
packimage rhels8.5.0-ppc64le-netboot-service
rinstall <SN> osimage=rhels8.5.0-ppc64le-netboot-service

Install xCAT-openbmc-py on RHEL 7 MN

The following repositories should be configured on your Management Node.

  • RHEL 7.5 OS repository

  • RHEL 7.5 Extras repository

  • RHEL 7 EPEL repository (https://fedoraproject.org/wiki/EPEL)

  • Fedora28 repository (for gevent and greenlet)

  1. Configure RHEL 7.5 OS repository

  2. Configure RHEL 7.5 Extras repository

  3. Configure RHEL 7 EPEL repository

    yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

  4. Create a local Fedora28 repository and configure the MN to the FC28 Repo

    Here’s an example to configure the Fedora 28 repository at /install/repos/fc28

    1. Make the target repository directory on the MN:

      mkdir -p /install/repos/fc28/ppc64le/Packages

    2. Download the rpms:

      cd /install/repos/fc28/ppc64le/Packages
wget https://www.rpmfind.net/linux/fedora-secondary/releases/28/Everything/ppc64le/os/Packages/p/python2-gevent-1.2.2-2.fc28.ppc64le.rpm
wget https://www.rpmfind.net/linux/fedora-secondary/releases/28/Everything/ppc64le/os/Packages/p/python2-greenlet-0.4.13-2.fc28.ppc64le.rpm

    3. Create a repository in that directory:

      cd /install/repos/fc28/ppc64le/
createrepo .

    4. Create a repo file /etc/yum.repos.d/fc28.repo and set its contents:

      [fc28]
name=Fedora28 yum repository for gevent and greenlet
baseurl=file:///install/repos/fc28/ppc64le/
enabled=1
gpgcheck=0

  5. Download and install xCAT-openbmc-py :

    wget https://xcat.org/files/xcat/xcat-dep/2.x_Linux/beta/xCAT-openbmc-py-RH7-2.14.6-snap202204090016.noarch.rpm -O /tmp/xCAT-openbmc-py-RH7.noarch.rpm
yum install /tmp/xCAT-openbmc-py-RH7.noarch.rpm

Install xCAT-openbmc-py on RHEL 7 SN from MN

Attention

Instructions below assume Service node has access to the Internet. If not, a local EPEL repository would need to be configured on the Management node, similar to the RHEL Extras repository.

  1. Copy Packages directory containing gevent and greenlet rpms from /install/repos/fc28/ppc64le to the directory pointed to by otherpkgdir attribute of the osimage.

    # Display the directory of otherpkgdir
lsdef -t osimage rhels7.5-ppc64le-install-service -i otherpkgdir -c

# Create Packages directory
mkdir /install/post/otherpkgs/rhels7.5-alternate/ppc64le/xcat/Packages

# Copy rpms
cp /install/repos/fc28/ppc64le/Packages/*.rpm /install/post/otherpkgs/rhels7.5-alternate/ppc64le/xcat/Packages

  2. Configure otherpkglist attribute of the osimage

    chdef -t osimage rhels7.5-ppc64le-install-service otherpkglist=/opt/xcat/share/xcat/install/rh/service.rhels7.ppc64le.otherpkgs.pkglist

  3. Add the following entries to the contents of /opt/xcat/share/xcat/install/rh/service.rhels7.ppc64le.otherpkgs.pkglist

    ...
xcat/Packages/python2-gevent
xcat/Packages/python2-greenlet
xcat/xcat-core/xCAT-openbmc-py

  4. Choose one of the 3 methods below to complete the installation

Install on diskful SN using updatenode

If SN was installed without xCAT-openbmc-py package, updatenode can be used to install that package.

  1. Sync EPEL repository and key file

    rsync -v /etc/yum.repos.d/epel.repo root@<SN>:/etc/yum.repos.d/
rsync -v /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 root@<SN>:/etc/pki/rpm-gpg/

  2. Update packages on SN

    updatenode <SN> -S

Install on diskful SN using rinstall

  1. Configure synclists attribute of osimage

    chdef -t osimage rhels7.5-ppc64le-install-service synclists=/install/custom/netboot/compute.synclist

  2. Add the following to the contents of /install/custom/netboot/compute.synclist

    ...
/etc/yum.repos.d/epel.repo -> /etc/yum.repos.d/epel.repo
/etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 -> /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

  3. Install SN

    rinstall <SN> osimage=rhels7.5-ppc64le-install-service

Install on diskless SN using rinstall

  1. Add EPEL online repository https://dl.fedoraproject.org/pub/epel/7/ppc64le to pkgdir attribute of osimage:

    chdef -t osimage -o rhels7.5-ppc64le-netboot-service -p pkgdir=https://dl.fedoraproject.org/pub/epel/7/ppc64le

  2. Install diskless SN

    genimage rhels7.5-ppc64le-netboot-service
packimage rhels7.5-ppc64le-netboot-service
rinstall <SN> osimage=rhels7.5-ppc64le-netboot-service
