Site-aware zipl environment
A site-aware zipl environment supports failover setups accross multiple sites. You can define a sections in a zipl environment file for each site of your failover environment, thus providing flexible boot configurations across sites, see Figure 1.
Each section can have site-specific keyword-value pairs defined that replace kernel parameters at boot time. For details on how to create sections, see Defining sections in the zipl environment file.
You use the load parameter specification to select a site-specifc section when setting up re-IPL with chreipl or booting with the IPL command. On the HMC, the field is Load parameter. For details, see Activating site-specific kernel parameters.
