How to Make SPARCstorage Array Disks Available Early in the Boot Process

Add the following forceload entries to /etc/system file to ensure that the SPARCstorage Array disks are made available early in the boot process. This is necessary to make the SPARCstorage Array function as a system disk (boot device).

*ident	"@(#)system	1.15	92/11/14 SMI" /* SVR4 1.5 */
*
* SYSTEM SPECIFICATION FILE
*
...
* forceload:
*
*	Cause these modules to be loaded at boot time, (just before mounting
*	the root filesystem) rather than at first reference. Note that
* 	forceload expects a filename which includes the directory. Also
*	note that loading a module does not necessarily imply that it will
*	be installed.
*
forceload: drv/ssd
forceload: drv/pln
forceload: drv/soc

When creating a root (/) mirror on a SPARCstorage Array disk, running the metaroot(1M) command puts the above entries in the /etc/system file automatically.
