[Networker] NetWorker 7.3 undesired features?
2006-01-10 22:26:24
I installed NetWorker 7.3 yesterday. Here are some notes on features
that I have not yet seen discussed on this list.
nsrwatch
--------
(We use this a lot)
The Device section.
It used to show devices that were full as "(full)" when done. This
was very useful. It now only shows that when it the last operation
was read. So it shows "reading, done (full)" but not "writing, done
(full)".
The Sessions section
Cloning session progress is now fairly useless (unless you are
cloning a single save set). There appears to be an attempt to get
better progress information (as in Version 5?). In version 6 and
earlier version 7s, the progress showed the number of save sets that
were complete, the total space those savesets occupied, and the total
space to complete the command. Now the number of complete savesets
is not updated regularly, and it only shows the progressive spce used
for the single saveset in progress. I suspect Legato intended to add
the progress of the incomplete saveset to the total of the already
completed savesets and got it all wrong!
The line has 5 pieces of information:
(a) Number of completed save sets.
(b) Total number of save sets for this cloning session.
(c) the source volume.
(d) volume of data already cloned.
(e) Total volume of data for this cloning session.
All versions of NetWorker (that I have used) seem to have got (b),
(c), (e) correct.
All previous versions of NetWorker (pre 7.3) that I can remember get
(a) correct.
There have been various attempts to get (d) correct. I think version
5 and earlier did get it right. Under 6 and 7.0-7.2, this showed the
space of the completed save sets, unless the source volume changed,
in which case it showed the same as (e) until the next save set
completed.
mminfo
------
mminfo -q 'volume=A00921,volume=A02310' -r volume,pool,location
Matches every volume I have, not just the two volumes on the command
line. This is contrary to the man page, and used to work!
nsradmin
--------
This used to do some regular expression matching with queries.
So you used to be able to go:
print name: /dev/rmt/[0123]hbn
and get details for /dev/rmt/0hbn /dev/rmt/1hbn /dev/rmt/2hbn /dev/
rmt/3hbn.
You now have to use:
print name: /dev/rmt/0hbn, /dev/rmt/1hbn, /dev/rmt/2hbn, /dev/rmt/3hbn
There are also many changes to the jukebox resources to enable the
new parallelism features.
nsrjb
-----
The following has been discussed, but I add my observation. I think
this may be an improvement. I am not sure what will happen if I
deposit a new blank tape.
"nsrjb -d" now seems to do the inventory step as well. Whereas
before I had to do a "mmlocate -u" (to remove my out-of-library
location), "nsrjb -d" and "nsrjb -I", "nsrjb -d -Y" is all that is
required.
The jukebox now also appears to unload tapes that are not being used
after some period of time. [A feature discussed on the list in
recent weeks]. But I do not have DDS, and cannot correlate the time
delay after last use with any obvious parameters.
