4. If steps 1, 2 or 3 did not reveal a problem, use HP Command View EVA to request the HSV
controller to shut down the drive enclosure. Completing this action will halt the drive enclosure
data transfers.
5. Contact your authorized service representative and request assistance.

EMU conditions

The format of an EMU condition report is 0.7.01.ec, where:
• 0.7. is the EMU element type number
01. is the two-character EMU element number
•
• ec is the error code
NOTE:
There is only one EMU in a drive enclosure. Therefore, the element number is always 01.

Resetting the EMU

In some cases, the only corrective action for an EMU error is to replace the EMU. Call your authorized
service representative if this action is required. Another option is to reset the EMU using the following
procedure.
1. Firmly grasp the EMU mounting handle and pull the EMU partially out of the enclosure.
NOTE:
You do not need to remove the EMU from the enclosure or disconnect the cables. You must
avoid putting any strain on the cables or connectors.
2. Wait 30 seconds, and then push the EMU in and fully seat the element in the backplane. The
EMU should display any enclosure condition report within two minutes.
