Optional procedure on how to configure additional host entries in cray_net.
If one or more aarch64 compute nodes have been repurposed as login nodes, then host entries for aarch64 login nodes should be added to the cray_net service in the CLE config set. They will have their hostnames and any desired aliases added to the system's generated /etc/hosts file. Hosts can be added using cfgset update in interactive mode, using cfgset update with worksheets, or using cfgset modify commands.
- Add a host entry for a login node.
This will give the hostname login1_aarch and two additional aliases.
smw# cfgset modify -a login_aarch64_1 cray_net.settings.hosts.data p0
smw# cfgset modify -s "aarch64 login node 1" \
cray_net.settings.hosts.data.login_aarch64_1.description p0
smw# cfgset modify -s c0-0c0s2n0 \
cray_net.settings.hosts.data.login_aarch64_1.hostid p0
smw# cfgset modify -s login1-aarch \
cray_net.settings.hosts.data.login_aarch64_1.hostname p0
smw# cfgset modify -a login1-arm -a login1-aarch64 \
cray_net.settings.hosts.data.login_aarch64_1.aliases p0
- Run cfgset update -m prepare p0.
smw# cfgset update -m prepare p0
- Ensure the config set is valid.
