BUSINESS IMPACT
-----------------------
The issue has the following business impact: Can not recover needed data from certain tapes.

Changes

The tape media, required to recover the data, had been sent off site then brought back for a data recover project.

Cause

The tape drive appears to have been enrolled correctly, however the tape in question, had been sent offsite and was returned and the encryption key was missing.

Solution

A FE task was opened to have the tape drive re-enrolled with the customer's local OKM server, but it did not appear to help.

Even after the tape drive was re-enrolled the customer still was not able to read data off of a certain tape cartridge.

The problem was that the tape the customer was trying to recover data from, had been sent off site and brought back again.

The customer's encryption team imported the encryption key back to the OKM cluster.

They were then able to recover the data from the tape.
