text: **Tapes**
  Consider the following recommendations that relate to tapes: 
  
  (cid:2) Modify (CBROAMxx)**MAXTAPERETRIEVETASKS**and**MAXTAPESTORETASKS**(if you are using tape 
  retrieves because the default=1). Both of these parameters are configured at the global 
  level and at the storage group level. 
  
  (cid:2) The global level**MAXTAPERETRIEVETASKS**(tasks) is defined by**SETOAM**.**SETOAM**specifies the 
  total number of concurrent tape retrievals that are possible at a time. (It controls the 
  maximum number of tape drives that can be concurrently allocated to the OAM address 
  space for reading object data from tape.) This number must be less than or equal to the 
  number of tape drives on the system. Do not specify a number that is greater than the 
  number of tape drives that are available to OAM for the**MAXTAPESTORETASKS**or the 
  **MAXTAPERETRIEVETASKS**subparameters because a system can go into allocation recovery 
  and attempt to allocate tape drives after all of the tape drives are in use, causing system 
  problems.
