Info

After the Expert Partitioner panel has been accepted, the SUSE Yast2 utility detects that a configuration change has occurred that impacts the boot loader. As illustrated in Figure 4-53, a pop-up will be displayed asking if the default boot loader location should be set. Click Yes. Figure 4-53 SUSE Linux Enterprise Server 11: Set default boot loader location pop-up 244 SAN Boot Implementation and Best Practices Guide for IBM System Storage
To ensure that the boot loader is configured to use a multipath device, the Booting section of Installation Settings must be reviewed. It is accomplished by selecting the Booting option as seen in Figure 4-54. Figure 4-54 SUSE Linux Enterprise Server 11: Installation Summary / Installation Settings (expert) Chapter 4.
