Re: CPP6310 - Interface error: Device TAPMLB01 (resource TAPMLB01) -- MIDRANGE-L

I would open a (pre-)PMR. After explaining what has happened, you will probably be asked to provide some system dump data *before you power cycle the device and vary off the MLB.

When I’ve done this the QMGTOOLS are helpful in gather the data that IBM needs to see and be able to send it to them.

I had an Interface failure, CPP3610, on my 3573 Fiber Channel 4 Half Height Tape library.
Caused multiple BRMS failures.
Two of the four drives were in a failed status, another was deallocated.
Varying off/on the TAPMLB01 did not resolve the issue.
Library would not reboot via the GUI interface.
Took a midnight trip to the data center to power down/recycle the library.
All errors cleared.

I had a similar issue back in March, Library would reboot, took a midnight trip.
This failure the power button was non-responsive, had to pull the power cords to reboot the tape library.

Reviewing the issue/errors, and the fact that two drives went into a failed state, (each port on the ENOA controls two drives)
the root cause was either
1) the EN0A- PCIe3 16Gb 2-port Fibre Channel Adapter
2) or the Cisco 9148 Fiber channel switch.

Is there any way to determine the root cause?
A new VTL is in progress, but if the TAPMLB01 library is not the root cause, can this same type of error occur on a VTL?

Any thoughts from the group?
