Conrad; I went through this procedure and it worked, but its not
quite right. I need to assign five of the 14 tape drives for NDMP
and both the GUI and nsradmin say that the NDMP button in the tape
resource is read only and cannot be changed. When I ran jbconfig,
it asked if any of the devices were for NDMP and I said yet, but it
never prompted me for the storage node name, password, and other info.
Does anyone have any ideas on how to fix this?
I figured it out. In 7.4, the jbconfig utility works differently than
7.2.1. With 7.4, jbconfig never prompted me for the NDMP drive
details. I was wrong to assume a prompt would appear. What I did was
repeat Conrad's process a second time, but then when I got to the
devices that we use for NDMP backups, I had to change the path from
the default to the NDMP style path. For example, for my first NDMP
drive, I had to change /dev/rmt/5cbn to hostname:/dev/rmt/5cbn. As
soon as I did that, it asked me if it was for NDMP. I responded in
the affirmative, then jbconfig prompted me to enter the password.
Also, since I have tape pools set up with drive assignments, I had to
go through all my tape pools and deassign them before I could delete
the devices. In 7.4, when you do three way NDMP backups on your
NetWorker server, it also creates a storage node resource for the
entire tape library. I discovered that this storage node resource was
also duplicated, so I deleted the duplicates before I ran jbconfig a
second time.
Unfortunately, after I did all this stuff, the tape library resource
lost its connection to the media database, so I am in the process of
inventorying all 751 tapes. That process has a ways to go. I am
having trouble where a tape gets inventories in one of the NDMP
devices; it reports communcaitions errors, so I am doing a reset now
and I will disable those drives until the inventory is done.
Otherwise, tapes are mounting in the other devices now to be read. I
also discovered that I had to reconfigure the timer settings in the
tape library resource because I started to see communications
errors. As soon as I increased the timer settings by 20 seconds, the
errors went away and the inventory proceeded smoothly.
