The process for updating firmware on the IBM Power9 Server (Boston) is documented below.
Collect the following files and put them into a directory on the Management Node.
- pUpdate
- pnor
- bmc
If running rflash in Hierarchy, the firmware files/directory must be accessible on the Service Nodes.
Using xCAT rflash command, specify the directory containing the files with the -d option.
rflash <noderange> -d /path-to-directory/
The pUpdate utility is leveraged in doing the firmware update against the target node and will do the following:
- power off the host
- flash bmc and reboot
- flash pnor
- power on the host
Monitor the progress for the nodes by looking at the files under /var/log/xcat/rflash/.
Use the rinv command to validate firmware level:
rinv <noderange> firm | xcoll
