How do I use volume ID

I have no idea what are you describing. The only time I saw volid mentioned was during relabeling of tapes.

Why would you use volume ID for anything at all? But anyway, each volume has volume id. You can find it as part of volume label and you can find in media database to be recorded.

For example, mminfo -av -q volid=976472604 -r volume will tell you volume which belongs to volid.

How to find other things you can see in manual for mminfo.

It is not - it is related to volume.

Hi this is the message I got:

media info: verification of volume "backupserver_c102",volid 976472604 succedd.

I've just not had a lot of experience with the media database. I'll do what you suggest I just didn't know how the volume ID related to SSID

Oh I see. Usually message like that you see when tape reached physical end of tape. NW will then try to randomly access some data at the end of tape and thus perform kind of verification of the volume. Usually you will see something like:

nsrd: media notice: LTO Ultrium-2 tape 000001 on \\.\Tape0 is full
media notice: LTO Ultrium-2 tape 000001 used 1239 GB of 190 GB capacity
media info: verification of volume "000001, volid 1576063759 succeeded.
nsrd: write completion notice: Writing to volume 000001 complete

So this message is nothing to worry about and something to expect each time tape has been marked full once that it reached physical end of tape.

he didnt state it, but if he is seeing this all the time, it may be that someone has turned on the "verify on unload" option.

Oh yes, that would be another possibility (I remember Legato didn't encourage users to use it before as that functionality was broken).
