The tool you´re looking for is flarcreate , and it comes with your Solaris distribution.
Flar => Flash archive
A flash archive is a snapshot of a complete system, including all installed software, users , drivers and so on.....
Example to create a full (also incremental possible) flash archive on a Solaris 9 SPARC server with compression enabled:
root@sun-test-3 # flarcreate -n full-flash -R / -c -x /net full-flash
where
-n => the name seen at installation time
full-flash => the name seen on the filesystem
-c => compress
-x => exclude directories, in example /net will be excluded
-R => your root directory, or where to start (i think / is default)
I think this is what you are looking about...
see also "man flarcreate"
You can load the flash image over the network (NFS,HTTP,FTP) in a DR situation from a file server....

FLASH(9) BSD Kernel Developer's Manual FLASH(9)
NAME
flash -- subsystem for flash-like memory devices
SYNOPSIS
#include <dev/flash/flash.h>
device_t
flash_attach_mi(const struct flash_interface *fl, device_t dev);
DESCRIPTION
Flash-like devices can register themselves to the flash layer with the flash_hw_if structure. This structure has function pointers and other
fields.
The attachment can be done by calling flash_attach_mi() with this structure and the device's device_t as an argument. Return value is the
flash layer device. The flash_interface structure is shown below.
struct flash_interface {
int (*erase) (device_t, struct flash_erase_instruction *);
int (*read) (device_t, off_t, size_t, size_t *, uint8_t *);
int (*write) (device_t, off_t, size_t, size_t *, const uint8_t *);
int (*block_markbad)(device_t, uint64_t);
int (*block_isbad)(device_t, uint64_t);
int (*sync) (device_t);
int (*submit)(device_t, struct buf *);
/* storage for partition info */
struct flash_partition partition;
/* total size of mtd */
flash_addr_t size;
uint32_t page_size;
uint32_t erasesize;
uint32_t writesize;
uint32_t minor;
uint8_t type;
};
