Maintaining Mirrored Systems 3

This chapter contains procedures you are likely to need to maintain a disk-mirrored system, including replacing disk drives, recovering from disk failures, and using the olds scripts.

Using the alternate boot device

When you set up your mirrored system, you created an alternate boot device named bootdevice2.

The alternate boot device is a fail-safe device. If for some reason you are unable to boot from the primary boot disk—a corrupted boot disk, for example—you can tell the system to boot from the alternate device until further notice.

You do that by entering one of the following commands, depending upon whether you are at the boot prompt or in root:

_________________________________________________________________

ok setenv boot-device bootdevice2

#eeprom boot-device=bootdevice2

_________________________________________________________________

To reset the boot device to the primary disk, enter one of the following commands, again depending upon whether you are at the boot prompt or in root:

_________________________________________________________________

ok setenv boot-device disk

#eeprom boot-device=disk

_________________________________________________________________
