MHVTL config on RHEL5

[chandan]

Hi Nia,

I tried to install, but showing lot of messages, could you please help me regarding this.

Please find the attached log file.

FYI,
[root@localhost mhvtl]# uname -a
Linux localhost.localdomain 2.6.18-53.el5 #1 SMP Wed Oct 10 16:34:02 EDT 2007 i686 i686 i386 GNU/Linux
[root@localhost mhvtl]#

Warm Regards,

Chandan,

From what I read in the log, it seems that you sucessfully build kernel modules and started mhvtl.
You should check - as suggested - with lsscsi -g and ps -ef|grep -i vtl

Kind regards, Olivier

Yes, it looks like you have successfully installed mhvtl.

"
Could not locate library config file: /etc/mhvtl/library_contents.10
Creating a default one
Please stop mhvtl & edit /etc/mhvtl/library_contents.10 to suit your requirements

Could not locate library config file: /etc/mhvtl/library_contents.30
Creating a default one
Please stop mhvtl & edit /etc/mhvtl/library_contents.30 to suit your requirements
"

This message is normal when you run mhvtl the first time ..

You just need to install "lsscsi" ... try to do "yum install lsscsi"

[nia]

Also, can I ask you to try the dev release http://sites.google.com/site/linuxvtl2/mhvtl-2010-09-23.tgz?attredirects=0 as there were many fixes included that have not made the stable release yet.

Hi Nia,

As per your instruction I had installed lsscsi, now its working fine, shell I go head and install netbackup software
so that my netbackup master server(windows server 2003) running on VM ware workstation can able to communicate with my media server that is RHEL 5 where i configured MHVTL.

Thanks a ton for your great support.

Yes, mhvtl is ready now .. The next step would be to install NetBackup media server software on your RedHat Box and you should be all set from there ...

Good Luck ..

Hi Nia,

I have installed netbackup 6.5 on RHEL 5 where I installed MHVTL. But the thing master server(windows 2003 netbackup 7) is not recognizing the media server after installing netbackup 6.5 media server software on RHEL 5. So Could you please confirm me whether I have to install any other RPM/Software so that my master server can able to recognize the media server.

Warm Regards,
Chandan

You haven't supplied much info on the NetBackup problem..

The NetBackup Install Guide is very helpful, along with the NetBackup Trouble-shooting guide. Available on the CD's or from http://www.symantec.com/business/support/index?page=landing&key=15143

However, one common mistake is not adding the media server to the "SERVER = " entry in bp.conf (unix) registry (windows)

Can you please supply the master server & media server hostnames, and the output of "bpgetconfig" run on the master server..

p.s. Don't forget this is a 'mhvtl' forum, not a NetBackup forum..

Cheers
Mark

[Mark Harvey]

One other thing..

For some reason, NetBackup does NOT like the 'SPECTRA LOGICS' defined tape library..

I would edit the /etc/mhvtl/device.conf and replace the SPECTRA with STK/L180 or STK/l700
Then re-start the mhvtl.

Cheers

Hi Mark,

Thanks for your updates, however please find the required information regarding netbackup on attached files.

Could you please let me know where I can contact for netbackup issues, as I'm new to this domain.


Cheers!!

Next step is to check name resolution:
(bpclntcmd is linked into the resolver libraries just like the rest of NBU, so it is perferred)
(All 4 cmds below to be run on both hosts)
bpclntcmd -hn chandan-fk34yz5
bpclntcmd -hn chandan-c907884
Also
bpclntcmd -ip <ip address returned from above cmds>


You should get a speedy response. Otherwise check out name resolution for problems.

Next check communication from media server to 'bpcd' port on master server
$ telnet chandan-fk34yz5 13782
(press return twice to come back to a prompt)
You should not have any delays between initial connect and pressing return to get back to the cmd prompt.
This also confirms name resolution on the master server of the media server.

You can try Symantec forums : http://www.symantec.com/connect/backup-and-archiving/forums/netbackup

Hi Chandran,

Though this is not a forum for NetBackup, but this could be your answer.

I think you forgot to add your media server hostname into your master server.
goto host property, click master server, double click your master server will bring up the global
attribute, click on server and add media server at the below portion of the screen,
restart your netbackup service for both master & media servers, you should see your media server under the
Host Property, Media server list.

Check your bp.conf file at media server located at /usr/openv/netbackup, the first line servername
should be your master server hostname.

good luck.

[Mark Harvey]

OK, the problem is with media server 'name'

The master server is configured with "chandan-c907884" hostname as the media server.
MEDIA_SERVER = chandan-c907884

Yet, when looking thru the 'bp.conf' on the media server, it thinks the hostname is : tapi

Your name resolution has to be correct !!
Make sure your master server can correctly "bpclntcmd -hn chandan-fk34yz5" and 192.168.43.129 is returned.
Make sure your master server can correctly "bpclntcmd -hn <media server hostname>" and 192.168.43.130 is returned.
Make sure your master server can correctly "bpclntcmd -ip 192.168.43.129" and  chandan-fk34yz5 is returned.
Make sure your master server can correctly "bpclntcmd -ip 192.168.43.130" and return the correct hostname.

Make sure your media server can correctly "bpclntcmd -hn chandan-fk34yz5" and 192.168.43.129 is returned.
Make sure your master server can correctly "bpclntcmd -hn <media server hostname>" and 192.168.43.130 is returned.
Make sure your media server can correctly "bpclntcmd -ip 192.168.43.129" and  chandan-fk34yz5 is returned.
Make sure your media server can correctly "bpclntcmd -ip 192.168.43.130" and return the correct hostname.

Note: The NetBackup 'bpclntcmd' is preferred over nslookup/dig/host as bpclntcmd is linked into the resolver libraries just like the rest of NetBackup. Hence using the 'bpclntcmd' you can determin what is being returned to NetBackup.

I use redhat 5.1 after upgrading kernel to 2.6.30, this step every time
 # Modprobe scst
 # Modprobe scst_tape
 # Modprobe scst_changer
 I did not find these files, then no way to continue. You are successful, the operation can send a document to a workable me.
 I mail [e-mail]
