How do I copy disk-to-disk First, run format on the original disk to get the sizes of the partitions: # format /dev/rdsk/0s7 Opening '/dev/rdsk/0s7'. Reading the geometry block. /dev/rdsk/0s7 Integral SCSI revision 0, SCSI disk model 2 megabytes: 2046 physical cylinders per drive: 2046 physical heads per cylinder : 32 physical sectors per head : 64 physical bytes per sector : 512 physical 2048 drive description blocks at block 4184064 4096 diagnostic blocks at block 4186112 3600 revolutions per minute geometry block version 2 flaw map size is 0 bytes partition 0 76800 kbytes 0 start kbyte partition 1 97280 kbytes 76800 start kbyte partition 2 358400 kbytes 174080 start kbyte partition 3 204800 kbytes 532480 start kbyte partition 4 1048576 kbytes 737280 start kbyte partition 5 306176 kbytes 1785856 start kbyte partition 6 0 kbytes 0 start kbyte partition 7 3072 kbytes 2092032 start kbyte 2095104 kbytes used 0 kbytes unused format: quit Next, run format on the destination disk and set each partition to be the same as the original disk. Follow the directions in format for setting up the partition sizes. Next, run newfs on each partition that you will be copying. For example, say the destination disk's address is 3 (/dev/rdsk/3sN, where N is the partition number): # newfs -F /dev/rdsk/3s0 # newfs -F /dev/rdsk/3s2 # newfs -F /dev/rdsk/3s3 # newfs -F /dev/rdsk/3s4 # newfs -F /dev/rdsk/3s5 Next, run fsck on each of the partitions (unless they are XFS type) Finally, copy each original directory to the corresponding destination directory using dd: # dd if=/dev/rdsk/0s0 of=/dev/rdsk/3s0 bs=32k # dd if=/dev/rdsk/0s2 of=/dev/rdsk/3s2 bs=32k # dd if=/dev/rdsk/0s3 of=/dev/rdsk/3s3 bs=32k # dd if=/dev/rdsk/0s4 of=/dev/rdsk/3s4 bs=32k # dd if=/dev/rdsk/0s5 of=/dev/rdsk/3s5 bs=32k if= specifies the input file of= specifies the output file bs= specifies the block size to use for copying (high number = faster)
