Configure DAL Mounts (Optional)

Optional procedure on how to configure DAL mounts.

If the system has a direct attached Lustre (DAL) filesystem that is mounted on login nodes, in addition to adding the login_nodes_aarch64 node group to the client_mounts setting of the cray_lustre_client service, the auto boot file must be modified to mount the DAL filesystem on the aarch64 login nodes after it is started with the lustre_control start command.

Modify the auto boot file to mount the DAL filesystem on the aarch64 login nodes after it is started with the lustre_control start command.
The following example assumes that the auto file has the following two lines to start the DAL filesystem and then mount it on the existing login node.
```
lappend actions { crms_exec_on_bootnode "root" "module load lustre-utils; lustre_control start -f dal" }
lappend actions { crms_exec_on_bootnode "root" "module load lustre-utils; lustre_control mount_clients -f dal -w login" } 
```

Add the two new nodes to the second line if the two aarch64 login nodes were added to the system with hostnames login1-aarch and login2-aarch.

lappend actions { crms_exec_on_bootnode "root" "module load lustre-utils;lustre_control mount_clients -f dal -w login,login1-aarch,login2-aarch" }
