The Copy Utility Tool allows you to back up data from a SCSI disk device, and at a later time, to restore the data from the backup medium to the desired disk. The tool offers the following functions: File, Backup, Restore, Verify and Option.
CAUTION: The Copy Utility Tool contains commands which can destroy data. For example, the Backup and Restore commands will overwrite pre-existing data on the target device.
The Copy Utility Tool supports SCSI hard disks, DDS and 8mm tape drives. Within this category, the Copy Utility supports only those devices that are supported by Hewlett Packard Company. If the device is not an HP-supported device, the Copy Utility tool displays a warning message, but allows users to proceed at their own risk if they chooses so.
If the backup device is a disk, its size must be equal to or greater than the size of the disk being backed up. In other words, for a disk-to-disk copy, the size of the destination disk must be be equal to or greater than the size of the source disk.
If the backup device is a tape drive, this tool supports backup on multiple tapes. When the copy reaches the end of the current tape, this tool prompts you to insert the next tape and continue.
This tool reports any error(s) detected during the course of its execution. It terminates its task as soon as the number of errors detected exceeds the allowable number of errors. Tool progress and detailed information about the errors are logged in the Copy Utility Activity Log.
If you experience problems, consult the Troubleshooting help topic.
To run the Copy Utility Tool on a device:
To back up data from a SCSI disk:
If the backup device is a disk, its size must be equal to or greater than the size of the disk being backed up. In other words, for a disk-to-disk copy, the size of the destination disk must be be equal to or greater than the size of the source disk.
If you run into problems, see the Troubleshooting help topic.
To restore data from a SCSI backup device to a SCSI disk:
To verify data by comparing data on a SCSI disk with the copy on a SCSI backup device.
Consult the tool's Activity Log, accessible from the Utility submenu of the main UI command level.
Make sure the device is connected, powered on, and on-line.
If the selected disk is a system (root) disk, some of the Copy Utility Tool functions can cause the computer system to become slow to respond.
You can stop the executing function by pressing the Control-C Key and then pressing the ABORT or INTERRUPT function key. To stop the tool entirely and return to the STM main menu, select the ABORT function key.
The Copy Utility Tool may be waiting for you to respond to a query message it is displaying. Answer the query and continue.
The Copy Utility Tool requires a license to operate. Install the license and try to run the tool again.
The Copy Utility Tool offers the following menu commands and function keys:
Use the Save As command to save the contents of the Tool's main window to a file. (Only the most recent 200 lines can be saved.)
Use the Print command to print the contents of the Tool's main window. (Only the most recent 200 lines can be printed.)
Use the Exit command to exit from the Copy Utility Tool.
The Start Backup command allows you to back up data from a SCSI disk to a SCSI backup device.
You may use the Set Option command to specify the maximum number of errors allowed before the task terminates. This allowable error count applies only to read errors from the source device. If the tool detects any error when writing to the backup device, it reports the error and terminates the operation regardless of the maximum allowable error count.
If the backup device is a disk, its size must be equal to or greater than the size of the disk being backed up. In other words, for a disk-to-disk copy, the size of the destination disk must be be equal to or greater than the size of the source disk.
The Start Restore command allows you to restore data from a SCSI backup medium to a SCSI disk.
The maximum number of errors allowed set by the Set Option command has no impact on the restore operation. If the tool detects any read or write error, it reports it and terminates the operation regardless of the maximum allowable error count.
The Start Verify command allows you to validate the data in the backup or restore copy.
You may use the Set Option command to specify the maximum number of errors allowed before the task terminates. This allowable error count applies to read errors from both the source and target devices. When the number of the errors detected exceeds the maximum allowable one set by the Set Option command, the tool terminates the verify task.
The Set Option command allows you to specify the maximum number of errors before the tool terminates the ongoing task. This maximum allowable error count affects only the Start Backup and Start Verify commands.
The counter of errors is re-set every time a new task is initiated. For example, after you execute a Start Verify operation, if the number of errors detected exceeds the maximum allowable value, the tool terminates this task and returns to the main screen. On the next task (perhaps Start Backup), if the number of errors detected during the backup operation is greater than the maximum allowable value, the tool terminates the backup operation and returns to the tool's main menu.
The General Help command displays online help for the Copy Utility Tool (the help system you are currently viewing).
For information on using the help system, select the "HELP ON HELP" function in the main STM Help menu.
For online help on STM as a whole, use the Help menu in the STM main menu.
The Version command displays version and copyright information for the Copy Utility Tool.
Pressing Control-C (CNTL-C) allows you to interrupt or abort execution of tool, or to escape to the user interface. After you press Control-C, the following function keys are displayed:
The ESCAPE TO UI function key allows you to disconnect from the currently executing tool and return to the main UI command level. To reconnect to the tool, use the ATTACH function key in the UI.
The INTERRUPT function key allows you to interrupt the tool.
When the tool receives the interrupt, it stops whatever it is doing and asks you if you want to continue with the operation. If the reply is "Continue", the tool resumes what it was doing at the time of the interrupt. If the reply is "Abort", it terminates the operation and returns to the Copy Utility main menu and function keys.
The tool may not immediately receive the interrupt as it could be in the middle of an operation that should not or could not be interrupted. The interrupt is received as soon as the tool completes the operation.
The tool will receive and ignore user interrupts when it is already in the process of returning to the main menu and function keys.
All three operations, Backup, Restore and Verify, can be interrupted and terminated in the middle of the operation. Interrupt and subsequent termination do not negatively affect the source device in those operations and the target device of the Verify operation. However, if the operation is Backup or Restore the data on the target device will not be usable after the interrupt and subsequent termination, because the operation was stopped at the middle and only partial data were copied over.
The ABORT function key allows you to abort the tool.
The tool will be requested to abort and the state of the tool execution in the system map will be set to ABORT_PENDING. When the tool actually exits, its state will be set to ABORTED.
The CONTINUE function key allows you to continue with tool execution. The tool will continue execution just as if the Control-C key had not been pressed.
