Problem with Media Library 3581 and internal Drive LTO2

Hi guys and girls

Today I get Media Library 3581, autoconfigurator created following devices:

Opt Device Type Text
TAPMLB01 *MLB CREATED BY AUTO-CONFIGURATION
TAP04 3580 Tape Unit

But status is:
TAPMLB01 VARIED ON
TAP04 VARIED OFF

If I tried to Vary On TAP04 I get message:

Message ID . . . . . . : CPD2616 Severity . . . . . . . : 40
Message type . . . . . : Diagnostic
Date sent . . . . . . : 02/17/10 Time sent . . . . . . : 13:32:20

Message . . . . : Device TAP04 vary failed. No recovery attempted.
Cause . . . . . : Device vary failed. Reason code is 00003404. Reason
codes have these meanings:
--00003404: An error occurred during vary on processing.
Recovery . . . :
--00003404: Check your hardware to ensure it is connected correctly and is
powered on. Look for any tape VLIC logs (major code 2E00) or error logs
that were created around the time of failure which may indicate the problem.
Then try the request again. If the problem occurs again report the problem
(ANZPRB command).
