na_dd - Copies blocks of data.
dd [-c]
[ [if= file ] | [ din= disknum bin= blocknum ] ]
[ [of= file ] | [ dout= disknum bout= blocknum ] ]
count= number_of_blocks
dd copies the specified number of blocks from source to
destination. Source and destination may be specified as
either a file that is a fully qualified pathname, or as a
starting block on a disk. The parameter blocknum may range
from zero to the maximum number reported by na_sysconfig
(1) -r. When indicating a starting block on a disk, both
disknum and blocknum parameters must be specified. If the
source is missing, input is taken from standard input; if
the destination is missing, output is sent to standard
output. If the number of blocks exceeds the size of the
file, copying stops upon reaching EOF.
By default, dd copies data and checksum data for block
checksum disks, and treats all blocks as data blocks for a
disk in a zoned aggregate or advanced_zoned checksum
(AZCS) RAID group. When the -c flag is specified, dd
copies both data and checksum data for a disk in an AZCS
RAID group. The -c flag has no effect on a disk in a zoned
checksum aggregate.
