Failure to Import and Export Data

Publication Date:  2015-07-31 Views:  10 Downloads:  0
Issue Description
Products and versions:
  • VTL3500 V100R002
  • VTL6000 V100R003
In the navigation tree of the VTL Console, data cannot be imported or exported between virtual tapes and physical tapes.
Handling Process
Possible cause 1: Tapes of the virtual tape library (VTL) have a different capacity from tapes of the physical tape library (PTL).

1.  If the end-of-media-hit error message is displayed, the capacities do not match. You need to create virtual tapes, which must have the same capacity as physical tapes.

2.  If you have enabled data compression, check whether virtual tapes and physical tapes have the same real capacity rather post-compression capacity.

Possible cause 2: The PTL is in an abnormal state.

1.  Check whether the physical tape drives need to be cleaned or moved to proper locations.

2.  Check the event log or system log (/var/log/message on Linux) for error messages related to PTLs or physical drives.

3.  Check the element address of the PTL and ensure that drives of the VTL are assigned according to the element address of the PTL.
Root Cause
Possible causes are:

Cause 1: Tapes of the virtual tape library (VTL) have different capacities from tapes of the physical tape library (PTL).

Cause 2: The PTL is in an abnormal state.
