IT48342: DISMOUNT OF A NEWLY USED SCRATCH TAPE FAILS WITH ANR8355E I/O ERROR READING LABEL USING 8.1.27 SERVER

APAR status

• Closed as program error.

Error description

• After upgrading IBM Storage Protect server to version 8.1.27,
  the
  dismount of a scratch tape, can fail with:
  
  
  
  ANR8355E I/O error reading label for volume xxxxx in drive
  xxxx.
  
  This only happens when encryption is set in the device class for
  
  
  an LTO drive, and checktapepos is set to no.
  
  It does not affect already used tapes, that are not scratch.
  
  
  In the following example, the following configuration was set.
  
  Devclass -> Drive Encryption: On
  
  q vol xxxx  f=d ->  Drive Encryption Key Manager: IBM Storage
  Protect
  
  The Library GUI ->  Encryption -> "Application Managed
  Encryption"
