Non Pre-programmed RLM Card Replacement Procedure.

Solution

Description
Information needed to replace Non Pre-programmed RLM card in SL500.
Before Powering off the library:

Run and record the following CLI (Command Line Interface) commands: (save data in case of problems when unit is returned to operation).

   a. library getconfig

   b. frameinfo print

   c. network print

 Verify that the serial number and the frame and feature info is correct for this unit. (This is not an optional requirement).

To assure data is mirrored from the RLM to the RLC you need to use the CLI command "Shutdown" to start the procedure.  

Failure to follow this step or any of the steps in the virgin RLM replacement procedure will wipe out all internal data on the RLM and RLC cards and you will have to revert to the old RLM replacement process in <document: />.

• Library code MUST be at v1048 or higher.

• NOTE - YOU MUST BE CAREFUL with a new FACTORY purged & non-programmed RLM card.  There is no way to tell it from a USED RLM just by looking at it.  Take care not to compromise it before installation or you will have to Order a new one per <document: /> 

The RLM is the backplane for the SL500 library.  The backplane is installed on the back wall of the base module behind the card cage, drive slots, power supplies, and fans.

Steps to Follow
New Non-programmed RLM Replacement Rules:

1. An RLM card can only be replaced if the original RLC card is available to be reinserted into the new RLM card.

2. The RLC and RLM cards CANNOT be replaced simultaneously.

3. The replacement non-programmed RLM card must be un-used and from the area depot.  It cannot come from another machine or have been loaded into another machine without going back through the factory purge and rebuild process.

4. Failure to observe these rules will result in loss of library data that cannot be restored on site, and a machine specific 'Code A' RLC card will need to be ordered from the factory.

5. Any RLM removed from a library must be returned to the factory for purging of current data in the RLM and re-programmed.

CAUTION: ESD Sensitive: Damage may occur to the RLM, RLC, RLW, MPW, or MPU2 cards.  Make sure you follow the ESD procedures in the Safety section.

6. Issue the CLI command "shutdown".

Note:
The shutdown command mirrors configurable values from the RLM card to the RLC card such as serial number, WWNs, passwords, network settings, SCSI command values, etc. It also parks the robot and issues a halt to the processor.

7. Wait until the robot is parked before proceeding to the next step.

8. It is important to fully read pages 194 - 236 of the StorageTek SL500 Replacement Parts Catalog, PN96120 Rev.E, BEFORE you start replacement process.

You only get one chance to do this procedure if you do not follow all the steps in order you will almost always corrupt or destroy the data in the RLM and RLC cards and you will not be able to continue until a new pre-programmed RLM card is built for you by manufacturing.  The data can not be recovered once it is corrupted or destroyed and you will have to revert to the old RLM replacement process: SL500 - Procedure to Order a Programmed Replacement RLM Card (Doc ID 1013985.1)

Note:

There can be different points of failure on the RLM card that may cause different library components not to function while others remain functional such as the robot, keypad, and front door switch.   If any one of these components are not functioning, you may be required to manually raise the robot's X-table into its parked position.

Note:

• Recommendation from David Hunt in UK Training:

• Now a message appears on the CLI like this:
• SERVICE>> shutdown
•  
• --------------------- WARNING !! ---------------------
• Proceeding with this command will render the library inoperative and terminate this CLI session.
• You will no longer be able to log on and a full power cycle will be required.
• ------------------------------------------------------
• Do you wish to proceed with shutting the library down? (y, yes, n, no) y
•  
• Shutting down library..
• ------------------------------------------------------
• Syncing files ..
• Parking robot (this may take a while)
  
• Robot park complete
• Halting the library
• OK
• SERVICE>> Terminated

 It is suggested that when the message TERMINATED is seen, it is time to power down the library.
