Re: [Networker] Cloning idle read and write
2006-03-13 11:23:47
Hi Jonny,
Sounds remarkably familiar..
I've had a case open on this hang situation with Legato support for
about 18 months now. I know another customer at Nokia is having the same
issue.
It seems to be specific to Solaris, and cloning on Storage nodes. The
HBA's, drives, IP network, specific versions of Networker don't seem to
make any difference to the symptom.
We first saw the issue on 7.1.1. We're now on 7.2.1 because the
Networker development team said that changes had been made to the tape
selection code (the bit where the problem probably lays) in that
release, but (as you've seen), no joy. The support analyst has asked
that we start the investigation from the ground up again, so I'm loosing
hope of the issue ever getting resolved. We do a large quantity of
cloning, but currently the Master server (a VERY hard working E280) is
having to do all the work, as the Storage nodes get in to this hang state.
Feel free to e-mail direct if you want further info, or are willing to
add your voice to our efforts to get Legato to fix this.
Thanks
Will

Hi
This is my first post to this list, I have been lurking for quite a while
now.
We are running Networker Server 7.2.1.Build.311 on a Sun Fire 480R on
Solaris 8.
One of the backup clients has 2 stand-alone DLT7000 tape drives, running on
a UltraSPARC 2 on Solaris 2.6
It is running Networker Client 6.1.3.Build.428
The backup runs successfully. The cloning is then run, however near
completion I see in the nwadmin GUI
reading, idle
writing, idle
And will it remain that way until I kill the nsrclone process.
Has anyone encountered this before?
Cheers
Johnny
