WORM capability doesn't work in mhvtl.
Hello Guys,
I created WORM tape using mktape command in mhvtl.
#mktape -l 10 -m W00003LW -s 500 -t WORM -d LTO6 WORM #mktape -l 10 -m W00002LW -s 500 -t WORM -d LTO6 WORM
I can see both of them under /opt/mhvtl and in /etc/mhvtl/library.contents.10
However when i label them in WORM pool.These tapes don't get labeled as WORM tapes because they are still be seen as NON-WORM tapes.
I tried a lot but i think there is an issue in emulator (mhvtl). It's not WORM capable. If it is then it should label the WORM tape in the WORM pool.
Any chance of obtaining the syslog (/var/log/messages) ? I've only ever used NetBackup against WORM media - and that was several major versions ago. You should find the media behaves like worm - in that you can't rewind to previous block/filemark and attempt to re-write data. However, what mode page/log page updates should be performed may not be updated correctly. Hence the request for syslog - so I can see what pages are being requested from the backup application.
Thanks Mark
Hello Mark,
I have attched the /var/log/messages as you requested.
Moreover some information about the machine of mhvtl
Hello Mark,
Good morning !! Did you get chance to look into the logs attached ?
Hello Mohit,
I've had a quick look at the logs and can't see anything stand out. While the screenshot went unrecognised - the logs show it is NetWorker. So, I thought I'd spin up a copy and see if I could recall how to set it up (it's been ~20yrs since I last seriously used nsr). Any hints on how to setup WORM would be good. I'm currently having troubles finding a CentOS version where I can actually install my copy (8.22) - all sorts of GLIBC-2.x errors when trying to install the RPMs.. I think I'm going to have to try and get a more recent version of NetWorker :)
Can I confirm you are using the latest (github) version of mhVTL or a pre-built RPM ? If so - what version.
Hello Mark, Below is the procedure to setup WORM label, media pool for your ease.
At first we need to identify whether our device (tape-drive in our case) is WORM/DLTWORM capable or not. To check this in networker we can go to:
Devices --> Libraries --> Select your library --> Choose or select a drive --> Properties.
Under device properties, Select Information tab and check WORM and DLTWORM capable parameter.
As you can see above, your device is WORM capable but not DLTWORM capable because it’s an LTO tape drive and not the DLT (digital Linear tape) tape drive. Networker automatically sets these attributes and, consequently, they are read-only and cannot be changed.
Creating a WORM media pool.
Create a Label template first to be used by WORM media pool. To achieve this, from your NMC select: Media --> Select Label Template --> right click --> Click New.
Create label template window will appear. Choose the name of the Pool as WORM and fields as per your infra-requirement and click OK.
WORM label template created to be used for WORM pool as shown below.
To create WORM media pool, Select Media pools --> Right Click --> Click on New.
Create media pool window will appear. In General tab, Fill the Pool name, type, and label name. In Label template, Select the template WORM created by us earlier.
In the selection criteria tab, Select the drives which are WORM capable as per your requirement. You can set the target media type and media type preferred as per your tape and drive model and made. In my demo case, I am keeping it as by default (empty).
In configuration tab, make sure to check the WORM pool ticked under WORM configuration.
Keep the other fields as it is by default and click OK to create WORM media pool. Now we can see a WORM pool is created under media pools.
Now try to assign a WORM tape into WORM media pool. When we have a WORM tape/media available in our PTL then we don’t need to change the default properties of WORM tape handling parameter.Below is the default setting for WORM tape handling parameter.
Now we will try to label a WORM tape into a WORM pool created by us. Here in our demo environment, We have WORM tape available with barcode as W00003LW
Hello Mark,
Hope you are doing great now-a-days !! By any chance, Have you tried testing WORM ?
I've got my hands on NetWorker 19.9 - I've not had a chance to install/configure it. Hopefully tomorrow..
Which all packages have you installed on server? You need to install client, extended client, storage node, authc, server and nmc package in the same order as I've written. Run and check if you are able to see all the packages with the command. rpm - qa | grep - i lgto
Later you need to configure authc and nmc after successfull installation.
I actually left it to RPM to figure out install order :)
rpm -Uvh lgtoclnt-19.9.0.0-1.x86_64.rpm lgtoman-19.9.0.0-1.x86_64.rpm lgtonmc-19.9.0.0-1.x86_64.rpm lgtonode-19.9.0.0-1.x86_64.rpm lgtoserv-19.9.0.0-1.x86_64.rpm lgtoauthc-19.9.0.0-1.x86_64.rpm lgtoxtdclnt-19.9.0.0-1.x86_64.rpm
The result is:
[root@mhvtlNetWorker ~]# rpm -qa --last | grep lgto
lgtoman-19.9.0.0-1.x86_64 Thu 17 Aug 2023 16:13:34 JST
lgtonmc-19.9.0.0-1.x86_64 Thu 17 Aug 2023 16:13:33 JST
lgtoserv-19.9.0.0-1.x86_64 Thu 17 Aug 2023 16:13:29 JST
lgtoauthc-19.9.0.0-1.x86_64 Thu 17 Aug 2023 16:13:20 JST
lgtoxtdclnt-19.9.0.0-1.x86_64 Thu 17 Aug 2023 16:13:17 JST
lgtonode-19.9.0.0-1.x86_64 Thu 17 Aug 2023 16:13:14 JST
lgtoclnt-19.9.0.0-1.x86_64 Thu 17 Aug 2023 16:13:12 JST
I shall uninstall and re-install in the above order.
Re: configure authc & nmc Yep, installed latest JRE from Oracle and the configure steps appeared to be successful.
Good morning MArk,
Just saw your commens. You can refer the below txt file for installation steps:- Networker server Installation-Linux .txt
Hello Mark,
Hope you are doing good today. Wishing you a wonderful day ahead !!
Just wanted to know if you are gradually moving towards the testing :-)
Sorry - still trying to get the NetWorker installed and running. I assume 'nsrd' should be running on the 'server' (It's an all-in-one setup). I can manually start 'nsrd' and nsradmin then connects. But nsrd doesn't start by itself via any 'systemd/rc scripts' I've forgotten how NW determines if it's the server or just a storage node. (or is that dependent on packages installed ?)
GM Mark,
YES, server package needs storage node package. As you said, it's all in one setup so you should have all the packages installed as I explained earlier. Please refer my installation steps notepad attached earlier to accomplish your installation. Moreover see recommended system specifications like ram, cpu and your disk space especially /opt for networker to be running.
Thanks.

System specification for my LAB networker backup server. Just for your reference.
#systemctl stop gst #ps -ef | grep -i gst (make sure all the NMC processes are stopped for java-based networker management console) #systemctl stop networker (Stop networker)
ps -ef | grep -i nsr (no networker process should be running)
delete all temporary files under or from /nsr/tmp. #systemctl start networker (start networker )
tail -30f /nsr/logs/daemon.raw (monitor networker logs) (wait untill your storage node is in ready state)
ps -ef | grep -i nsr (make sure all networker processes are running)
systemctl start gst
#ps -ef | grep -i gst
Login to the the NMC now.
Hello Mark,
Hope you are doing great !!.
I just want to let you know that i am still waiting and relying on your testing with WORM.
Hello Mark ,
Good Afternoon ,Hope you are doing good !!
Do you have any update on the issue i reported to you ? Let me know if anything else is reuired from me .
Thanks & regrads, Mohit .
Still having problems getting NetWorker to start up.
Any chance of confirming which NetWorker processes are actually running on the server node ?
I'm off for a couple of weeks without access to my computer. I'll be checking into it further when I get back.
Thanks for the patience. Mark
