Troubleshooting IBM Installations¶
Opening Port 12345¶
For default IBM Power9 systems with RHEL 7 installed, be sure to open port 12345 in the firewall. For example:
firewall-cmd --zone=public --add-port=12345/tcp —permanent firewall-cmd --reload
Growing the Disk¶
Some users may find it necessary to grow their disk. An example describing how to add disk space to a virtual machine is available at https://www.geoffstratton.com/expand-hard-disk-ubuntu-lvm. The steps for an IBM Power9 system with RHEL 7 would be similar.
