Re: [Networker] The volid on tape and the one in media base is not the same!

Fazil,
If you are recommending that I use persistent binding, then I will have
to tell you that it is useless for me to do that because I have each
tape directly connected to a port on an HBA. Since persistent binding
has to do with multiple devices attached to a single port on an HBA it
doesn't help me. What I need is persistent binding at the OS level,
which is provided by the newer udev drivers for Linux by basing devices
on the WWNN of the tape drive (at least until I have to replace a faulty
drive).

Hello,
You may want to look at previous post on persistence binding etc to get
detail on how to correct tapes from re-sequencing.
Generally, you should use persistence binding with your HBA ( Details can
be found with previous posts).Newer Tape drivers allow you to use
persistence naming scheme ( Depending on your host OS , the process can
differ).Check driver release notes.
You may find it easier to implement this schemes and redo your jbconfig
etc & then you will have more stable environment.

Re: [Networker] The volid on tape and the one in media base is not the

The way I do that is to have NetWorker mount a tape in a drive and then
go look on the system to see if it got mounted in the correct drive.
I know which drive it should be, and use the mt command to check if it
is in that drive. If it isn't, then I can either go look at the drives
to see where the tape did wind up, or I can run mt commands against the
rest of the drives until I find the one that has a tape that shouldn't
(This is always easier if NetWorker isn't playing with the jukebox at
the same time).
