Rebuild the Media Information Region for T10000 Drives

Rebuild the MIR to recover from a bad RFID chip.

The T10000 tape drives use information recorded on each tape cartridge to reduce access times and manage the useful life of the cartridge. This information is recorded and stored in the cartridge's radio frequency identification (RFID) chip and at the beginning-of-tape (BOT) in an area known as the media information region (MIR).

Occasionally, the REBUILD MIR utility can try to recover from a bad RFID chip in the cartridge. If the utility fails, try the rebuild utility on more than one drive. If the utility still fails, create a dump file, and send it to technical support for analysis.

Note:

There is no special process to rebuild a MIR for the type of T10000 tape drive (A or B, and encryption-capable or unencrypted). The rebuild MIR process is an offline process that maps data and defects on the tape and does not care if the data is encrypted or not.

1. Make sure drive is unloaded before activating the Build MIR utility. Rebuild MIR flashes on the operator panel while the MIR is rebuilding.
2. Approximate time for a full tape Build MIR varies by the cartridge type:

   • Standard T1 Data cartridge is approximately 120 minutes.

   • Sport T1 Data cartridge is approximately 48 minutes.

3. If a CHKxxxx appears, see the FSC Dictionary for information.
4. Connect a tape drive to the VOP.
5. Use the Menu and Select buttons to navigate to the utility:

   • Press Menu to bypass

   • Press Select to activate.

6. When Ld Cust Tp appears, insert the write-enabled data cartridge with the invalid MIR.

   With encryption-capable tape drives, a series of messages may appear several times until the rebuild MIR operation continues. Examples of these messages include:

   KMS2.0: my_tcp_connect select returned 0 err=236(op now in progress)

   KMS2.0: AUDIT_CLIENT_GET_CLUSTER_Information_SOAP_ERROR

   KMS2.0: All drives keys turned off

   After these messages occur, the Rebuild MIR starts.

7. When the MIR is rebuilt, the cartridge unloads. Remove the cartridge.
8. Insert another write-enabled data cartridge requiring a MIR rebuild; or Press Menu to exit the build MIR submenu.
