Chapter 5 - Disaster Recovery for VINES

Backing Up VINES Servers

1. Create a VINES System Configuration backup tape. See "How to Back Up the VINES System Configuration Files" in this chapter of the guide.

2. Use NetWorker to back up your VINES servers as you would any server. Use the procedures detailed in the Legato NetWorker Administrator's Guide.

How to Back Up the VINES System Configuration Files

1. After EBR agent has been installed on the server, create a VINES System Configuration backup tape or disk, using the standard VINES backup/restore utility. Do this immediately after EBR agent is installed and configured, and whenever StreetTalk information stored on that server is changed.

2. Select Backup/Restore from the Operator Menu on the VINES server console.

3. Select Backup from the Backup/Restore Menu.

4. Select System Configuration Backup from the backup menu, and, when prompted, select Confirm Readability of the backup.

5. After the backup completes, store it in a safe, but convenient, location. You will need this backup if the boot disk is damaged or destroyed.

Restoring VINES and EBR Agent

1. Repair or replace the hardware.

2. Reinstall VINES, including the System Configuration files that you previously backed up.

If you are installing VINES 7.x, be sure to select the EBR installation option during the VINES installation so that you will not have to reinstall EBR agent later.

If you installed VINES 6.10 and above, up to but not including VINES 7.0, you must reinstall the EBR agent software.

3. Use the EBR menu on the VINES server console to recover data. Do this step from the server to which you are recovering data.

Note: Step 2 above also restores the TCP/IP settings. If the reinstallation does not restore the TCP/IP settings, you must do so.

How to Reinstall VINES

1. Re-install VINES from the distribution media.

The VINES installation procedure prompts "Do you want to reload a complete system backup (y/n):" Enter Y.

2. Select Continue with System Rebuild from the System Rebuild menu.

3. When prompted, insert the VINES System Configuration backup media and choose Continue to start the restore operation.

When the restore operation is complete, you are prompted to "Load Next Incremental in Series" or "Continue with Installation."

4. Choose "Continue with Installation."

VINES initializes the Mail service, if there is one, and loads the device drivers. Shortly thereafter, the Service Monitor initializes. Any services that exist with blank data areas show a status of inoperative. This typically occurs if the data area has not yet been restored.

5. If you are installing VINES 7.0 or above, reinstall the EBR agent from the distribution media.

6. After installing EBR, reboot the server to start the portmapper so the EBR agent can start.

EBR and NetWorker

Installing the EBR Agent on VINES 6.x

1. Log in to the network as a user who is on the AdminList of each server to which you will apply the patch.

2. Use DOS commands to select the drive from which you will be installing EBR (either the diskette or a network drive) as the active drive. For example, to install from a diskette in drive A:, enter the following commands at the DOS prompt:

A:
CD \EBR
DIR

The EBR directory includes the EBR agent and service executables that you install using the VINES 6.00 patch utility.

3. To install server executables, enter:

CD server

If you want to install EBR components on multiple servers, enter:

PATCH

If you want to install EBR components on a specific server, enter:

PATCH servername

servername is the name of a specific server on which you want to install the EBR components.

4. From the Patch Utility Menu, choose Install Patches. The Select Patch Names screen appears and displays the following text:

1 - EBR 1.1 Agent Installation 95/07/xx Range: 6.00(0)-7.00(0)
2 - EBR 1.1 Service Installation 95/07/xx Range: 6.00(0)-7.00(0)
3 - EBR 1.1 VINES 6.00 compatibility patch: 95/07/xx Range: 6.00(0)-7.00(0)
4 - VINES 6.00(10) Jukebox device drivers 95/07/xx Range: 6.00(10)-7.00(0)

5. Use the arrow keys to select patch #1 for any VINES server. Press ENTER to select. Press F10 when you have selected the patch you wish to apply. Do not select any patches other than #1.

6. If you specified a servername in step 3, proceed to step 8.

If you are installing EBR components on multiple servers, the Available Servers screen appears. The Available Servers screen displays information specific to each server selected, including its patch range. If the selected server's patch range is outside the range specified for this patch, you cannot apply this patch on that server.

7. Use the arrow keys to scroll through the list of available servers and choose one or more on which to install the selected EBR server components. To select a server, press ENTER. Pressing ENTER a second time deselects the server.

When you select a server, a line on the Available Servers screen displays information about that server. The following character codes may appear:

$ - Indicates that you selected the server
Z - Indicates that the server provides your Z drive
R - Indicates that the server is your routing server
AT, MC, or SMP - Indicates the server platform

The number that appears beside the server name indicates its position on the list of servers to be patched. For example: ...Z...R...AT.... 6 -$Admin1

This line indicates that server Admin1, an AT server, is the sixth server on the available servers list. In addition, the line indicates that Admin1 is the VINES file server (Z) and routing server (R) for this workstation.

8. After you select the patches to apply and the servers you want to patch, either:

- Press F10 to begin the installation as soon as possible (ASAP).

or:

- Specify the desired installation time. Press F4 to specify a later time for the installation to begin. Press Enter to continue.

9. Press F10. The Patch Utility begins copying files from the server directory.

Patch informs you of the total number of files being copied and incrementally displays the file numbers being copied. For example, a message similar to one of the following may appear:

Copying 57 files to server Admin1
Copying file #18

Files are copied to a temporary directory on the server until the time arrives for the component to be applied. The patches are applied to the selected servers at the time you specified on the Display Install Time screen or ASAP if you did not specify a time.

10. Install the EBR agent software option code that enables the EBR agent only. See "To Install the EBR Software Option Code" later in this guide.

11. After you install the desired EBR components and the software option code on a server, you may use MSERVICE to create and manage the service.

Installing the EBR Agent on VINES 7.X or VINES 8.x

1. From the Operator Menu on the VINES server console, select Shut Down Server Software.

2. From the Shut Down Menu, select Shut down services and return console to Operator Menu.

3. Insert the VINES 7.X or 8.X release media CD-ROM in the server CD-ROM drive.

4. From the Operator Menu, select Backup/Restore.

5. Select Reload EBR Files from Release Media. The system responds with this prompt:

If EBR files are reloaded, the server will automatically be rebooted.
Do you wish to continue? [y/n]:

6. Answer the prompt. The default is Y.

If you patched the server since installing the base software, you must reapply the most recent patch after loading EBR. The system checks for devices and prompts as follows:

DEVICE Drive found -- Do you want to load EBR Files from DEVICE? [y/n]:

The first device is the CD ROM. If you answer N to CDROM, TAPE is the next device. If you answer N to TAPE, the system assumes you want to use diskettes and prompts you to continue. The default for these prompts is N.

7. Answer the prompts appropriately.

- If you answer N to all three prompts, you return to the Backup/Restore menu.

- If you answer Y, the system loads the EBR files and reboots the server. Reapply a patch if so instructed in step 6.

8. Install the EBR server agent software option code. See "To Install the EBR Software Option Code," which follows.

9. After installing the EBR server agent and the EBR software option code, use a Banyan server management tool to create the service. You must reboot the server before you start the agent.

EBR Software Option Code

To Install the EBR Software Option Code

1. From the Operator Menu on the server console, select Shut Down Server Software.

2. From the Shut Down Menu, select Shut down services and return console to Operator Menu.

3. From the Operator Menu, select System Maintenance.

4. Select Manage Software Options.

5. Select INSTALL options.

6. Select Install OPTION CODE options.

7. Enter the 14-digit Option Code and the 3-digit Option Enabler at the prompts.

8. Press ESC until you return to the System Maintenance Menu.

9. Select Return to Operator Menu.

10. Select Restart Services.

Using EBR Server Agent to Restore VINES Services

Note: When you enter data during this procedure, such as server names, enter the data exactly as they were entered when they were defined. All entries are case-sensitive. If a name contains spaces, enclose the name in quotes (" ") or the EBR agent will not accept it.

1. Select Backup/Restore from the Operator Menu.

2. Select Enterprise Backup/Restore (EBR) from the Backup/Restore menu.

3. When prompted, enter the VINES administrator's StreetTalk name and password.

4. Verify that the server you are doing the recover on is looking for its files on the correct NetWorker server. Select Change Recover Source from the Enterprise Backup/Restore menu.

5. Locate the parameter "Use the EBR service on server:_______".

6. If you need to access a recover source (server) other than what is displayed, enter the name of the Windows NT NetWorker server that backed up the system.

7. Select Recover Server Data from the Enterprise Backup/Restore menu.

8. When prompted, select Continue to continue the current operation.

- If the data is valid, a list of services (alias view) is displayed followed by the EBR recover prompt (\\>). This list can be displayed by typing DIR. The list of commands can be displayed by typing ?

- If the data is not valid, you receive the message "unable to initialize alias root."

9. Using mark, select all services you want recovered. In this case, it would be all services on the Boot/Primary disk:

\\> mark servicename

You may use this command as many times as necessary. Be careful to mark the mail service, file service, and StreetTalk Directory Assistance service that you are recovering.

You could also select all services:

\\> mark *

and then deselect those services you do not want restored with unmark:

\\> unmark servicename

10. If you want to recover versions other than the most recent version, complete these steps:

- To choose the versions you want restored, you can review the backup time by entering:

\\> versions

- Mark the version you want to use:

\\> change time

- Enter the time.

11. To display which tape volumes are needed for the restore operation, enter:

\\> volumes

You can now locate the media containing those volumes.

12. To force an overwrite of existing files, enter:

\\> force

If you do not use force, you are prompted to accept the overwrite on any duplicate (existing) files.

Note: This is necessary because the data restored from the VINES System Configuration backup could be out of date.

13. Go back to the server console and enter:

\\> recover

This starts the recovery procedure.

14. Insert the first volume listed in the output of volumes into the tape drive.

15. On a NetWorker server, access the NetWorker Administrator module and mount the volume you just inserted into the drive.

16. Messages similar to these display:

Recovering 13794 files into their original locations. Total estimated disk space needed for recover is 246MB Not all Volumes are on-line (some off-line) SNI1.003 at /dev/rct4 SNI1.004

17. At the prompt "Proceed with Recover command at this time? [Y]", press Enter for yes. Check the Pending messages window in the NetWorker Administrator module to review the status.

18. After the restore is complete, enter:

\\>quit

A log file of the recover process displays.

19. To save the log file as a file, press F4. By default the log file is saved to drive Z.

20. If you are doing a full disaster recovery, reboot your computer.

EBR Console Operations

1. Select Backup/Restore from the Operator Menu.

2. Select Enterprise Backup/Restore (EBR) from the Backup/Restore Menu. You are prompted for your username and password, which are verified and stored for later use by those EBR Console operations that need them.

3. Enter your StreetTalk username and password. The EBR Main Menu appears.

When EBR Agent is installed, the following functions on the Enterprise/Backup Restore menu are not operational:

- 4 - Index Maintenance

- 5 - Local Tape Operations

- 9 - Configure EBR Mail User

Recovering Server Data

1. To recover backup data to a server, select Recover Server Data from the Enterprise Backup/Restore menu and press Enter. The Confirm Operation screen appears, prompting you to continue with the recover operation.

- If you select CONTINUE, the recover submenu appears.

- If you select ABORT, the EBR main menu appears.

The recover submenu provides access to the recover browser. Server data is organized in the recover browser hierarchical file system directory in a DOS or UNIX® view. The recover browser displays the following information:

- Services hosted on the server, listed by StreetTalk name. These always appear at the top of the hierarchy where the recover browser starts looking for data to recover.

- StreetTalk groups listed by StreetTalk name.

- Mailboxes (if the server hosts a mail service) listed by the owner's StreetTalk name.

- Mail Folders (if the server hosts a mail service) listed by folder name.

- Files and directories in VINES Files services listed by DOS name. Information about files and directories can be configured using the VIEW subcommand.

Verifying Recoverability of Data

1. Select Verify Recoverability of Data from the Enterprise Backup and Restore menu and press Enter.

The Confirm Operation screen appears, asking if you want to continue with the verify operation.

2. Select CONTINUE. The verify screen appears. You can browse your server's on-line index of backup data.

In addition, you can build a recover list of services, directories, and files that can be verified as recoverable.

3. To verify recoverability of data, use the recover browser to scroll through the index of saved data and build a recover list using mark and unmark. When you type verify from within the verify submenu, all the steps needed to recover the data (finding the volume, reading the tape, and so on) are performed, but the data is not recovered.

Changing the File Service Viewpoint

1. Select Set Default File Service View from the Enterprise Backup and Restore menu and press Enter.

2. Select the default view.

You can display files in DOS or OS/2, Macintosh, or UNIX views.
