You can copy a hard disk onto another hard disk easily through the Command Monitor. You may want to do this to create a backup disk in case of failure, or perhaps you have a specific software setup that you wish to copy for a new system. In order for this procedure to work correctly, and for the new disk to be useful, the disks must be of identical size and manufacture. Also, the system that is to receive the new disk must use the same CPU and graphics board set that the existing system uses, because the kernel is custom configured for CPU and graphics type, and the kernel will be copied exactly to the new disk.
Follow these steps:
Bring your system down and install the new disk in the space provided for an additional disk. Select a SCSI device number that is not currently in use for the new disk. For this example, we will use device 2 on SCSI controller 0 (the integral SCSI controller) for the new disk, and device 1 on SCSI controller 0 for the disk to be copied.
Boot the system to the System Maintenance Menu.
Select option 5 from the System Maintenance Menu. You will see the Command Monitor prompt:
>>
Give the sash or boot command to load the sash:
sash
From the sash prompt, give the command:
cp -b 128k disk(1)part(10) disk(2)part(10)
You see a ''read error'' message when the copy is complete. This is the normal message that tells you that the copying software has read the entire disk. If you see a ''write error'' message, there was an error copying the disk and you will probably have to start over or install the disk by more conventional means.
