        So I believe what you are saying is that a Primary copy of some
data has been destroyed and you want to recreate the onsite copy.

        Here is our procedure that is somewhat specific for a 3494 tape
library, but it has all the steps:


 Note: Words in ITALICS are examples of tape/storage pool names. You
must substitute these values with the correct ones.

   1. Update TSM database to reflect volume is destroyed.
          * TSM> update vol C00252 access=destroyed

   2. Find out what tape/tapes from the offsite copypoool are needed
from vault.
          * TSM> restore vol C00252 preview=yes
          * do "q proc" until process is gone.
          * TSM> q act sear=anr1255w (to get the list of tape/tapes it
wants).
      **** There will be a bunch of entries that look something like
this:

04/01/98   14:27:50  ANR1233I Restore preview of volumes in primary
storage
                      pool VMS_INCR_TAPEPOOL started as process 212.
04/01/98   14:27:50  ANR1255W Files on volume C00050 cannot be restored
-
                      access mode is "unavailable" or "offsite".
04/01/98   14:27:51  ANR1255W Files on volume C00239 cannot be restored
-
                      access mode is "unavailable" or "offsite".
04/01/98   14:27:51  ANR1255W Files on volume C00058 cannot be restored
-
                      access mode is "unavailable" or "offsite".
04/01/98   14:28:10  ANR1255W Files on volume C00032 cannot be restored
-
                      access mode is "unavailable" or "offsite".
04/01/98   14:28:56  ANR1255W Files on volume C00260 cannot be restored
-
                      access mode is "unavailable" or "offsite".
04/01/98   14:28:56  ANR1255W Files on volume C00083 cannot be restored
-
                      access mode is "unavailable" or "offsite".
04/01/98   14:28:56  ANR1255W Files on volume C00000 cannot be restored
-
                      access mode is "unavailable" or "offsite".
04/01/98   14:29:16  ANR1255W Files on volume C00268 cannot be restored
-
                      access mode is "unavailable" or "offsite".
04/01/98   14:29:17  ANR1235I Restore process 212 ended for volumes in
storage
                      pool VMS_INCR_TAPEPOOL.
04/01/98   14:29:17  ANR1241I Restore preview of volumes in primary
storage
                      pool VMS_INCR_TAPEPOOL has ended.  Files Restored:
43070,
                      Bytes Restored: 27207363132.

      In this case all 8 of these tapes would need to be retrieved to
restore the data from the bad tape.

   3. Retrieve offsite tape/tapes from vault and load into the library.

   4. Check the offsite tape/tapes into library.
          * TSM> checkin libvol LIBRARYX C00016 stat=private devt=3590

   5. Update access to the tape/tapes just loaded.
          * TSM> update vol C00016 acc=readonly

   6. Restore the files back to primary tapepool.
          * TSM> restore vol C00252
      It may take a while.

   7. Check to see that primary storage pool is up to date.
          * TSM> restore stg AIX_INCR_TAPEPOOL preview=yes
          * TSM> q act (preview should say 0 files restored, if not STOP
and call ADSMONCALL.)
          * To find out what pool the destroyed tape belonged to, use
the 'q vol C00252' command.

   8. Return tape/tapes 'restored from' back into the vault.
          * TSM> update vol C00016 access=offsite
          * TSM> checkout libvol LIBRARYX C00016 remove=yes
          * tape/tapes should be put in I/O slot by robot

   9. Remove the damaged tape from the database.
          * TSM> delete vol C00252
          * If this command fails, contact ADSMoncall before removing
the tape from the library.

  10. Remove tape from tape library if not already done so.
          * TSM> checkout libvol LIBRARYX C00252 remove=yes

Hello Everyone,

   I need to bring back some offsite tapes for a restore.  How do I
check them into the library, and then force Tivoli to use them.  I have
a tape that broke and now I need to bring back the offsite copy, but I
am not sure what how to set this up.  Should I bring back every tape for
that node that is offsite, any help is much appreciated.

Thank you 

James
