Saves information about base-customized devices in the Device Configuration database onto the boot device.
savebase [ -o Path ] [ -d File ] [ -v ]
The savebase command stores customized information for base devices for use during phase 1 of system boot. By default, the savebase command retrieves this information from the /etc/objrepos directory. However, you can override this action by using the -o flag to specify an ODM directory. By default, the savebase command writes the information it retrieves to the boot disk. Alternatively, you can use the -d flag to specify a destination file or a device, such as the /dev/hdisk0 device file.
The savebase command determines what device information to save using the PdDv.base field corresponding to each entry in the CuDv object class. Specifically, the PdDv.base field is a bit mask which represents the type of boot for which this device is a base device. The savebase command determines the current type of boot by accessing the boot_mask attribute in the CuAt object class. The value of this attribute is the bit mask to apply to the PdDv.base field to determine which devices are base.
Note: Base devices are those devices that get configured during phase 1 boot; they may vary depending on the type of boot (mask). For example, if the mask is NETWORK_BOOT, network devices are considered base; for DISK_BOOT, disk devices are considered base. The type-of-boot masks are defined in the /usr/include/sys/cfgdb.h file.
