I would advise you to open a support ticket with IBM.

When that error has been seen before, I believe one of the action plans was to cancel the recovery key operation and retry via CLI (prepare, confirm, commit).  However, without understanding the cause of the error then it is not possible to say if that would be appropriate here.

The CLI steps would be:

chencryption -recoverykey newkey -key cancel

and then prepare again using either the GUI or the CLI:

chencryption -recoverykey newkey -key prepare
chencryption -recoverykey newkey -key confirm
chencryption -recoverykey newkey -key commit

Support would be able to advise you.

Subject: Inquiry regarding recovery key generation error for FS7300 storage

Dear,

As requested by the customer, I performed USB encryption on the FS7300 storage.

Following the encryption, an error occurred during the recovery key generation process.

(Error Message : Array index out of range : 1)

While no subsequent errors have appeared, the recovery key is still not being generated.

Could you please advise on how to proceed with resolving this issue?

Thanks.
