IT26871: TABLE SPACE OFFLINE AFTER "ALTER TABLESPACE ... MANAGED BY AUTOMATIC STORAGE" COMMAND

APAR status

• Closed as program error.

Error description

• The problem can be reproduced with these steps:
  
  1) A non-automatic storage table space TS1 has a container named
  /home/db2inst1/db2inst1/NODE0000/SAMPLE/T0000004/C0000000.LRG,
  which is the same name/path as if it were created as an
  automatic storage table space.
  2) ALTER TABLESPACE TS1 MANAGED BY AUTOMATIC STORAGE
      -> It fails with SQL0299N
  3) ALTER TABLESPACE TS1 MANAGED BY AUTOMATIC STORAGE
      -> It succeeds
  4) Check db2diag.log. The table space is offline due to the
  following message:

Local fix

• Before altering the table space to automatic storage make sure
  the container name is different than if it was an automatic
  storage table space container.
