Installing RLMs into an image on a running non-ICE compute node

RHEL: 

cm node yum -n hostname install RPM RPM ...

SLES: 

cm node zypper -n hostname install RPM RPM ...
Removing RPMs from an image on a running non-ICE compute node

RHEL: 

cm image yum --duk -n hostname remove RPM RPM ...

SLES:

Commands for ICE compute nodes

Pushing ICE compute node images to a rack 
cimage --push-rack image_name rack_number

For rack_number, specify a rack number in the rX format.

Display ICE compute node images and kernels 
cimage --show-images
Display image, kernel, and file system mode of ICE compute nodes 
cimage --show-nodes rack_number

For rack_number, specify a rack number in the rX format.

Change the image, kernel, or file system mode of ICE compute nodes 
cimage --set [option] image_name kernel node

Update RPMs

Update RPMs on a node 
cinstallman --update-node --node hostname
Update RPMs on an image 
cinstallman --update-image --image image_name

VCS commands

Check in an image with changes or updates into version control 
cm image revision commit -i image_name -m "checking in"
Review version control history for an image 
cm image revision history -i image_name
Revert to a previous image version 
cm image revision revert -i image_name  --rev version_number

Directories

Review post-installation scripts 
ls /opt/clmgr/image/scripts/post-install
Configuration scripts directory 
/opt/clmgr/image/images/image_name/etc/opt/sgi/conf.d
Set up one-time PXE boot for HPE ProLiant DL360 Gen10, HPE ProLiant DL380 Gen10, and HPE ProLiant DL380 Gen9 server installation

Use one of the following methods to configure a one-time PXE boot on nodes with iLO devices:

  • From the admin node, use the following ilorest command: 

    ilorest bootorder --onetimeboot=pxe --url=iLO_IP -u ADMIN -p iLO_password --commit

    For iLO_IP, ADMIN, and iLO_password, enter the values for this cluster.

  • Use pdsh or ssh to log into a node, and then run one of the following commands: 

    • hpbootcfg -P -b

      or 

      efibootmgr options ...

  • On the node console, press F12 or Esc+@ (serial).

You can download ilorest and hpbootcfg from the HPE support website.
