Migrating a shared IBM 3494 library to a library manager

If you are sharing an IBM® 3494 library among Tivoli® Storage Manager servers by using the 3494SHARED server option, you can instead share the library by using a library manager and library clients.

1. Complete the following steps on on each server that is sharing the 3494 library:
   1. Update the storage pools by using the UPDATE STGPOOL command. Set the value for the HIGHMIG and LOWMIG parameters to 100%.
   2. Stop the server by issuing the HALT command.
   3. Edit the dsmserv.opt file and make the following changes:
      1. Comment out the 3494SHARED YES option line
      2. Activate the DISABLESCHEDS YES option line if it is not active
      3. Activate the EXPINTERVAL option line if it is not active and set the value to 0.
   4. Start the server.
   5. Enter the following Tivoli Storage Manager command:

      disable sessions

2. Set up the library manager on the Tivoli Storage Manager server of your choice.
3. Do the following on the remaining servers (the library clients):
   1. Save the volume history file.
   2. Check out all of the volumes in the library inventory. Use the CHECKOUT LIBVOLUME command and set the REMOVE parameter to NO.
   3. Set up a library client.
4. Do the following on the library manager server:
   1. Check in each library client's volumes. Use the CHECKIN LIBVOLUME command with the following parameter settings:
      • STATUS=PRIVATE
      • OWNER=<library client name>
        Note: You can use the saved volume history files from the library clients as a guide.
   2. Check in any remaining volumes as scratch volumes. Use the CHECKIN LIBVOLUME command and set the STATUS to SCRATCH.
5. Halt all the servers.
6. Edit the dsmserv.opt file and comment out the following lines in the file:

   DISABLESCHEDS YES
   EXPINTERVAL 0

7. Start the servers.
