IOS000I Message with Encryption Failure z/OS DFSMS Software Support for IBM System Storage TS1140, TS1130, and TS1120 Tape Drives (3592) SC23-6854-00 |
||||||||||||||||
If an encryption-related key exchange between the drive and the
key manager fails, an IOS000I message is issued indicating that an
encryption failure has occurred:
The control unit (CU), DRIVE, and Encryption Key Manager (EKM)
error codes are from sense bytes 08, 13-15, and 17-19, respectively.
For example:
In this example, the error
was reported by the Encryption Key Manager (EKM). For an EKM failure, refer to the Problem Determination section of the IBM System Storage Tape Encryption Key Manager, Introduction, Planning, and User's Guide, GA76-0418. When looking up the EKM failure, use the last two byes of the error code (for example, EE31 in the example above). For a control unit failure, refer to the IBM
System Storage TS1120 Tape Drive and Controller Operator Guide,
GA32-0556. Table 1 contains error codes for control unit
failures.
The The IBM System Storage TS1120 Tape Drive SCSI Reference, GA32-0562, lists the sense key, ASC, and ASCQ combinations that are reported for encryption conditions, along with a one-line description. For more detailed information about the drive-reported conditions, and also about the EKM-reported conditions, see the Problem Determination section of the IBM System Storage TS3500 Tape Library Operator Guide, GA32-0560. If there are multiple error codes reported, start with the EKM error code. In addition, any system-managed tape library scratch tape that receives the IOS000I ENCRYPTION FAILURE message along with an IEC512 I/O ERR, remains in a scratch status, but is updated in the Tape Control Data Base (TCDB) with a VOLUME ERROR STATUS of I/O ERROR. This causes it to be placed in the software error category, and the tape is unusable until the I/O ERROR condition is cleared through manual intervention (for example, use ISMF volume ALTER from scratch. Scratch moves the volume from the software error category back to the scratch category). Periodically, use the DISPLAY SMS,LIBRARY command with DETAIL to display the number of scratch volumes in the software error category. |
