LAN SYSTEMS BACKUP PROCEDURES

Overview of LAN Systems Backup Servers

The LAN System servers are located in a cabinet to the left of the IBM 3490E (Research Foundation’s) tape drives in the computer room. The servers are labeled as LSBACKUP1 and LSBACKUP2. There is a keyboard and monitor labeled the same way for each server. There are two tape drives on the LSBACKUP2 server and 1 tape drive on the LSBACKUP1 server. All the equipment is labeled with the server name and in the case of the tape drives the auto pilot set name is very important. A summary follows:

 

Server Auto Pilot Set Name Location

 

LSBACKUP1 LSBACKUP Middle right side of cabinet

LSBACKUP2 LSBACK2B Middle left side of cabinet

LSBACKUP2 FS1BACK Middle left side of cabinet

 

Note: The auto pilot set names LSBACK2B and FS1BACK are both on the same server.

Note: Always blank two tapes for the Weekly and Monthly Backup runs. The second reel may or may not be required.

Safe Retention

The Monthly backup tapes are held for two years. These tapes are stored in the gray cabinet next to the RF (Research Foundation) 8300 series tape rack for the RF system. The CURRENT Monthly tapes are in the tape rack with the Daily and Weekly tapes, but the previous Month’s tapes are stored in the vault in Fronczak Hall on the 1st floor. At the completion of each Monthly run, take the previous Month’s tapes from the Computing Center to the vault in Fronczak Hall and bring the older set back and place them in the gray cabinet in room 104 Computing Center.

Daily Procedure

  1. At start of second shift, pull the tapes for today’s backup from the tape library and fill out the log book located in the tape server cabinet.
  2. Remove the previous night’s backup tapes from the tape drives.
  3. Load the tapes for today in the proper drives making sure tapes also have an external label on them with date, type of backup , and server name.
  4. Blank each of the tapes. Always blank two tapes for the Weekly and Monthly runs. The second tape may or may not be required. It is best to blank the 2nd tape first, remove that one, and then blank the 1st tape and leave that tape in the drive for the backup to start.

Monitoring the Servers

The LAN servers consists of five windows. They are:

 

Arcserver Tape Server Window - used by us for blanking tapes and checking labels

System Console - used by us for checking for error messages

Monitor Screen - not used to us

Arcserver Message Screen - used by us for checking for error messages

Arcserve Scheduler Console - used to see if any backups are still active

 

Press ALT ESC to cycle through the windows. Press ESC to back up to a previous window.

 

Viewing the Tape Status

Check the tape status panel of each drive.

 

 

Check the "ARCSERVE TAPE SERVER". Console display located on the top shelf in the cabinet will show the display for both Lsback2b and Fs1back. Highlight DEVICE MANAGEMENT hit enter, then hightlight TAPE DRVIE STATUS and hit enter. This will show which backup is running and if the tape is labeled.

 

NOTE: It is important that you check the tapes to make sure they are blank. This is done by going to the ARCSERVER TAPE SERVER display and highlighting TAPE DEVICE MANAGEMENT then hit enter, then highlight ERASE then hit ENTER. A display will appear that shows the tape drives and the label of the tape on it. Remember, the tape must show BLANK before the backup starts. If the tape is labeled and needs to be BLANKED, then go to the BLANKING A TAPE section.

Changing Tapes

Make sure the "TAPE IN USE" light is not flashing on the drive that you want to unload.

 

Press ALT ESC to cycle to the Arcserve Scheduler Console screen and make sure there is no backup active. This is a very important step because it is possible to unload a tape and a backup is still active and will be aborted and must be restarted by Lan System’s staff.

 

Press "UNLOAD" button. When the green light appears next to the "OPERATE HANDLE", lift handle and remove tape.

 

Put in the next tape, make sure that it is properly labeled, then lower the handle.

Blanking a Tape

  1. Load tape in tape drive (see CHANGING TAPES section).
  2.  

  3. Press ALT ESC and toggle through until you get the "ARCSERVER TAPE SERVER" screen.
  4.  

  5. Under AVAILABLE OPTIONS window select "TAPE DEVICE MANAGEMENT" and press enter.
  6.  

  7. Under TAPE DEVICE MANAGEMENT WINDOW select "ERASE" and press enter.
  8.  

  9. The ERASE screen will appear, highlight the tape you wish to BLANK and hit enter (use up/down arrows to change tape drive).
  10.  

  11. On the ERASE screen the following will appear highlighted:
  12.  

    ERASE MODE: QUICK – ERASE ONLY DESTROY THE LABEL

     

  13. Press enter. The AVAILABLE OPTIONS screen will appear, it will show the following.

 

FULL ERASE (DESTROY ALL DATA AND TAPE LABEL)

QUICK – ERASE ONLY DESTROY TAPE LABEL

QUICK ERASE PLUS (DESTROY TAPE LABEL AND SERIAL NUMBER)

 

  1. Use the down arrow to select:

 

QUICK ERASE PLUS (DESTROY TAPE LABEL AND SERIAL NUMBER)

 

  1. Then press enter. Now press:
  2.  

    F2<DONE>, this will start the erase.

     

  3. The process takes approximately 1-2 minutes for each tape. To do more than 1 tape, press ESC until DEVICE MANAGEMENT screen appears then start process again.

Error Messages

Check the LAN Server consoles during each shift for any messages that are repeated every minute. If this happens, contact Sharon Arieno.

 

For example:

Oct 25 09:25:14 E1103 Unable to get media list

Oct 25 09:25:55 E1103 Unable to get media list

Oct 25 09:26:35 E1103 Unable to get media list

 

Here’s another message indicating a problem.

 

Media is device group ARCSERV2 is not in the scratch set of pool LSBACK2b_DLY. Please mount one of the following media in device group ARCSERV2:

Media Name Serial # Media Pool Seq.

1. D-LSBACK2B-XXX – X/X/XX XXXXXXX LSBACK2b_DLY 1

2.

3.

4.

5.<Blank>

 

The job will be cancelled in 9999 minutes.

 

The above message indicates that a blank tape needs to be inserted because the job is trying to start and it requires a blank tape. At this point, if you try to "blank" a tape and receive an error "error device open" then the alternative is to insert a new tape and job should start within a few minutes.

 

The following errors are only informational and do not require any intervention.
