That said, I'm frequently out of touch with reality . . . .

Hi Bruce

Actually, I've used NMC V7.4.x to configure libraries used by the
embedded storage node since the first EDL release that had that feature,
and it has worked reliably for me.

You obviously are not in touch with the reality of configuring libraries
in unix with the NW NMC. Rarely does the gui work, and almost always
jbconfig is required, via the command line.

Unless of course the qui actually works with 7.4, then I stand corrected
and apologize.

Hi

Why not use the NetWorker Management Console to manage the embedded
storage node?  After adding a storage node resource for the EDL embedded
storage node, select 'Scan for devices', select the embedded storage
node, click 'Start scan', and check Monitoring -> Log for progress.
When this completes, configure the library.  Once configured, you can
use the Properties tab for the autochanger and tape drives to view the
serial number (in the Device serial number field of the General tab).

I believe the embedded storage node was conceived with the premise that
you'd never need, or want, to log in to the EDL to run CLI commands like
'inquire', 'jbconfig', etc.  What do you need that you can't do with
NMC?

Thanks

I agree, there is a very good GUI application to manage the EDL, but
what's missing is a good way to manage the embedded storage node.  For
example, if I want to run an inquire command to get a listing of the
scsi devices, serial numbers, etc visible to the storage node, or if I'm
troubleshooting drive behavior with mt, I have to have EMC support open
an ssh session and have *them* login as root, as they will not hand out
that password.  I've heard, and we are trying to get this set up at our
site, that if you ask your TC nicely, he/she can have someone from EMC
set up a non-root linux user that has permission to run some of the
commands like inquire from the linux environment/embedded storage node.

This is one of the few medium grade annoyances I have with the EDL.
Another one is that, while there is a command-line interface to generate
reports about the EDL utilization, you have to log in to the GUI to get
them.  In a large environment I want to script and schedule that and
can't because of a design oversite.

One other comment about using the embedded storage node and cloning.
Assuming that a) your environment uses a shared-storage node to backup
up to the VTL and b) your budget allows for the licenses, I strongly
recommend that you zone the shared storage node to also see the physical
tape library, i.e. the embedded storage can see the VTL and the physical
library and so can the shared storage node.  The reason for this is
that, in the event that you have a connectivity problem between the ESN
and the PTL, you can clone from the shared storage node.  Clones from
the shared storage node may not happen as quickly, but the added
flexibility is well worth the minor cost. (Yes, we learned this the hard
way!)......
