LTO Ultrium compression logs
Hi,
I’m looking for a way to query the compression logs of a LTO Ultrium drive:
- (uncompressed) bytes received
- (compressed) bytes written to tape
- compression ratio achieved.
My research so far:
- in the past I used ddsinfo (for DDS) and tapeinfo (for DLT) but I haven’t found such a tool for LTO
- I have tried hptapeperf: it makes a predefined performance test and gives you the resulting compression ratio (not exactly what I’m looking for)
- STM gives you the compression ratio so far (as stored, I guess, in the drivers’s compression logs)
- TapeTool does allow you to view the compression logs (by generating a support ticket).
The latter would do the trick but I’m looking for:
- a simpler way (a standalone utility, much in the way of ddsdinfo-tapeinfo)
- if possible, including the ability to clear the compression logs (as ddsinfo-tapeinfo do).
Thanks in advance.
Best regards.

Re: LTO Ultrium compression logs
HP LTT has LTO compression test available.
