   Illustration 10	g03853114

5. After the device has been connected to the VM, some text will scroll by which is initializing the hard drive. After that, the hard drive should now be shown as connected on the ALP VM.

6. Repeat Steps 1 - 5 for any other drives that will be connected for copying to the NAS.

   Note: Only three autonomy log drives will be processed at a time. More than three drives can be plugged in, but the extra drives will not show up on the main screen. The Results Drive does not count as one of these three drives. This only applies to autonomy logger drives.

Disconnecting Drives

Illustration 11	g03853118

When drives are finished copying, a message will appear stating that the drive is safe to disconnect from the log transfer appliance. Disconnect the drive with the matching disc label.

Note: Removing the incorrect drive and removing one that is in the middle of a read/write process could potentially corrupt the hard drive and make all the data permanently lost. Confirm that the correct drive is being disconnected to prevent data loss.

LTA Results Drive

The Results Drive is a large capacity, shippable disk for moving large amounts of logs from a remote site back to Cat Product Support. When attached to the Log Transfer Appliance, logs are copied from the Network Attached Storage (NAS ) to the Results Drive. The Results Drive is shipped when full, or at a configurable interval.

The LTA will usually have a Results Drive attached and is expected. For example, with two drives per site, one drive remains at site while the other drive is shipped back to Cat Product Support.

When attached to the Log Transfer Appliance, the Results Drive will receive a compressed copy of all results. If the Results Drive is not full after a configured amount of time, then the drive will begin storing compressed copies of full incoming logs. When full the Results Drive is "closed", and made ready for physical shipment to Cat Product Support.

Note: Contact Cat Product Support for the address to ship the Results Drive to.

Preparing the Results Drive

Determine Mount Location on OCS

1. The data storage device to be formatted should NOT be connected yet. If a terminal window is not already open, open one by pressing "Ctrl + Alt + t".
   Show/hide table

   Illustration 12	g03853119
   Terminal screen shot

2. In the terminal, search for the existed mounted drives using the following command. Type "mount | grep /dev/sd", then press the "Enter" key. The display should show an output similar to the illustration below . This screen will show all the currently mounted drives.

   Note: The "|" symbol is a pipe character and not a lower case letter "L".

3. Plug the data storage device into the OCS laptop.

   If configured, a file viewer window may appear. Leave the window open, as the window can be used to show that the unmounting process has worked in the later steps.

4. Determine where the drive mounted. In the terminal, search for the existing mounted drives. Type "mount | grep /dev/sd", then press the "Enter" key.

   Note: Reformatting of the correct data storage device is CRITICAL.

   Show/hide table

   Illustration 13	g03853120
   Terminal screen shot

5. The screen will show all the currently mounted data storage devices. The new line shown is the data storage device that needs to be formatted. Record the information on screen that appears in the boxes in Illustration 13. This information will be needed in the upcoming steps.

6. Now that the mounting location has been recorded, the hard drive will need to be unmounted to begin the formatting. Type the following command to unmount the drive:

   umount /media/**Data Storage Device name**

   Note: **Data Storage Device name** represents the name of the device or drive name that was recorded in Step 5.

7. If this Step was executed correctly, the file viewer window (if applicable) that opened automatically in Step 3 will not show the data storage device anymore. The window may even close automatically.

Run the Formatting Script

1. Now that the drive is unmounted, change to the scripts directory by typing the following command:

   cd ~/software/scripts/

2. Type the following command to run the formatting script.

   sudo ./format_logging_disk.sh –r /dev/sdX

   Note: The "X" following "sd" in the command will be the drive letter that was previously recorded. Ensure that the number of the partition title is left off. "/dev/sdb1" would be entered as "/dev/sdb".

3. The user will be prompted to enter a password. Now enter the root/admin password and press "Enter".

4. A warning will appear on the screen asking to type "Continue" with a capital "C" to continue with the specified formatting.

   Note: Ensure that the correct mount location was selected or the PC hard drive can mistakenly be formatted.

   Illustration 14	g03853124
   Continue formatting screen

5. After the word "Continue", with a capital "C", is typed and if the hard drive has never been formatted with the script, the system will ask for the serial number written on the outside of the drive. Enter in the external serial number with no spaces and press "Enter".

   Note: If the drive has already been given the external serial number, then this step will be skipped and the formatting will continue without any more prompts.

6. Once the script returns to the command prompt, the results drive is now safe to disconnect .

Connecting the Results Drive

Note: Before proceeding, it is assumed that the results drive is configured and formatted as an ALP Result Drive.

Illustration 15	g03853128
LTA menu

When connecting the Results Drive, follow the same procedure as if connecting a normal autonomy log drive. The only difference between the two will be after the Results Drive is plugged in, the drive will show differently as it would show in the LTA menu.

Disconnecting the Results Drive

1. When the results drive is full, there will be a message indicating the drive is ready to be removed.
   Show/hide table

   Illustration 16	g06059537

2. Disconnect the results drive from the transfer appliance by unplugging the drive from the computer. Once disconnected, ship the results drive back to Cat Product Support.

Deleting the Copied Results Drive Logs (Results Manifest)

When a disk has arrived back to engineering and all the data has been copied back, the Results Manifest ID and or Manifest Word can be messaged to the remote site operator. When entered to the ALP maintenance page, it will delete the associated logs and results (clearing the space on the NAS) that are no longer needed, since the associated logs and results have been received by engineering.

Note: Do not perform these steps unless a Manifest ID or Manifest Word has been received to confirm purging data off the ALP. Improper use of this feature could result in data being removed that wasnot intendedto be purged.

1. Click inside the LTA VM screen to have the keyboard enter the VM console.

   Illustration 18	g06059543

4. Once enter has been pressed, the ALP will load the "Acknowledge Results Manifest" screen. The list will contain all the active and closed manifests of results drives. Using the provided Manifest ID or Manifest Word, enter in the matching number as shown below in green. Once the number has been typed, press enter.
   Show/hide table

   Illustration 19	g06059571

5. A confirmation will show up. Type "Yes" with a capital "Y" and press enter. Anything but that will return back to the Maintenance Interface window.

6. After enter has been pressed, the Results Manifest will delete all logs and snapshots off the NAS that have been acknowledged as being transferred back to engineering from the selected manifest. This action could take some time depending on how many logs have been deleted. After the purging of data has occurred, the ALP screen will return to the Maintenance Interface window as shown in Step 2.

7. To return to the main ALP screen, press "Alt + F1".

8. To pass the keyboard and mouse functions back to the host computer, press "Ctrl + Alt".

Troubleshooting

Transferring a Corrupt Log File

1. Connect the logger to an appropriate power supply and to an OCS laptop using a USB cable.

2. Transfer the relevant files to the OCS laptop.

   Note: The file names list times in UTC time not local time.

3. Transfer the files to Cat Technical Support as needed.

Resetting the Log Transfer Appliance VM

If the machine is not functioning properly, a restart of the machine may be necessary to make it work normally again.

3. Wait for the machine to reboot. When the machine has fully booted, the "Log Transfer Appliance" screen will appear.

Taking a Diagnostic Report

A diagnostic report should be taken whenever an unexplained issue happens with the ALP. When a diagnostic report is generated, the ALP saves the configuration state of each ALP VM and multiple logs from each, saving the diagnostic to a zipped file for later analysis. This method allows for Cat Product Support to analyze the zipped log files later and possibly determine the root cause of the ALP issue.

Note: If the ALP LTA VM is unresponsive, there is no way for the ALP to take a diagnostic report. If the VM is still responsive but experiencing an issue, a diagnostic report should always be taken to assist with troubleshooting analysis.

1. Click inside the LTA VM screen to have the keyboard enter the VM console.
   Show/hide table

   Illustration 23	g03853135
   Normal "Maintenance Interface" screen

2. Once inside the VM console, press "Alt + F3". The Maintenance Interface screen will appear.
   Show/hide table

   Illustration 24	g03853136
   VM console

3. Type "D" and press enter to generate a diagnostic report. The diagnostic report may take some time to generate. There will be some messages displayed at the bottom of the screen indicating which VM it is logging files from.

4. Once enter has been pressed, the ALP will ask for a reason of taking the diagnostic report. Be descriptive as possible in describing what is wrong with the ALP interface so that engineering can better troubleshoot the issue. Once the description has been typed, press enter to continue.

5. When the diagnostic report is finished generating, the screen will refresh and return to the normal "Maintenance Interface" screen as seen in Step 2.

6. To return to the main ALP screen, press "Alt + F1".

7. To pass the keyboard and mouse functions back to the host computer, press "Ctrl + Alt".

8. Notify engineering that a description of what the diagnostic report was taken. Include a short description of the failed behavior and what time it was taken.

Repairing a No-Software Log Transfer Appliance VM

If any of the ALP nodes are in a no-software state, the nodes can easily be recovered by using the ALP Maintenance Interface.

1. Click inside the LTA VM screen to have the keyboard enter the VM console.
   Show/hide table

   Illustration 25	g06059416

2. Once inside the VM console, press "Alt + F3". The Maintenance Interface screen will appear. Ifanyof the "Application Versions" show as "NOT_AVAILABLE", then the ALP has entered a no-software state for that specific node. Proceed to the next step if the VM has achieved this no-software state.
   Show/hide table

   Illustration 26	g06059419

3. Type "1" and press enter to reboot all the processing nodes. Once enter has been pressed, type "Yes" with a capital "Y" to reboot the nodes.
   Show/hide table

   Illustration 27	g06059423

4. The ALP LTA will now reboot all the nodes. Depending on the amount of the nodes present on the ALP, the node reboot may take some time, as there is a delay between the restart of each node to prevent the no-software state of the VM’s from occurring.
   Show/hide table

   Illustration 28	g06059444

5. Once all the machines have been sent the reboot command, the main window of the ALP Maintenance Screen will show up again. Sometimes, some of the machines may show up as "Offline". The "Offline" status is most likely because the software status check was performed before the node had finished rebooting. If this condition has occurred, proceed to the next step. If all the nodes have the same Application Version and none are in a no-software state, proceed to Step 7.
   Show/hide table

   Illustration 29	g06059448

6. A refresh of the Maintenance Interface window will have to occur to see if the node has booted correctly to have an Application Version. To do this type "R" and press enter.

   The screen will refresh with an updated query of all the nodes. If all the nodes have the same Application Version and none of theme are in the no-software state, continue to the next step. If a refresh of the Maintenance Interface window does not continue to get all the nodes with an Application Version, contact engineering to look into other possible solutions to the issue.

7. To return to the main ALP screen, press "Alt + F1".

8. To pass the keyboard and mouse functions back to the host computer, press "Ctrl + Alt".
