“-m” option. You should consult documentation on the usage of the “-m” option for mklvcopy.

4.Synchronize the newly created mirrors with the following command:

syncvg -v rootvg

5.Bosboot to initialize all boot records and devices by executing the following command:

bosboot -a -d /dev/hdisk?

where hdisk? is the first hdisk listed under the “PV” heading after the command lslv -l hd5 has executed.

6.Initialize the boot list by executing the following:

bootlist -m normal hdisk0 hdisk1

Note

Even though this command identifies the list of possible boot disks, it does not guarantee that the system will boot from the alternate disk in all cases involving failures of the first disk. In such situations, it may be necessary for the user to boot from the installation/maintenance media. Select maintenance, reissue the bootlist command leaving out the failing disk, and then reboot. On some models, firmware provides a utility for selecting the boot device at boot time. This may also be used to force the system to boot from the alternate disk.

7.Shutdown and reboot the system by executing the following command:

shutdown -Fr

This is so that the “Quorum OFF” functionality takes effect.
