[Veritas-bu] Linux, libraries and NBU 7.0.1
Good day Folks
Having some issues with visibility of libraries robots and tape drives on a
Redhat Media server. Not being a native 'nix admin I could use a hand.
Environment:
Red Hat Enterprise Linux AS release 4 (Nahant Update 5), 2.6.9-55.Elsmp
4x HP MSL 6062 Libraries with 2x E1200-320 NSRs and 4x LTO4 a piece
Under
2003r2 x64 Windows master (MSCS cluster) Robot control host, emm, catalog
Shared storage option
Along with
3x 2003r2 x64 media servers (these see all devices)
So on the RH:
All the devices are visible when cat is run against /proc/scsi/scsi
Also if I review the HBA hosts at the emulex HBAcmd all devices are visible.
If I service netbackup stop and run hp_ltt (library tape tools) I see one
library vs 4, I see 7 NSRs vs 8, and 12 drives vs 16.
Having the netbackup service and running tpautoconf from the local linux shows
the same thing.
Running Device discovery from the NBU console shows the same thing also.
Tpautoconf -report_disc Shows I have some missing paths that are my robots and
a couple of new drives but I am not sure what to make of this as all serial
numbers seem to show true to what is existing in the libs. (see below body)
I feel like I am on the cusp of fixing this but I am missing some syntax or bit
on knowledge for cleaning this up. Looking at tpconfig also but the switch
combos there look potentially hostile, though the menu drive looks more
friendly.
Your input would be appreciated as to recommended method to proceed in sorting
this out.
Thanks in advance
Regards

Re: [Veritas-bu] NBU and Clustered MSCS fileserver, Flashbackup?
So if I understand the people and the threads on this correctly I need to: 1. Create an additional LUN for each cluster resource group on my Fileserver. 2. add that LUN to the cluster resource group as disk. 3. On the drive properties for the data drives within a resource group, change the VSS settings to point to the newly created LUN, doing this on all nodes of the cluster I presume. 4. Add flashbackup to the policy, point it to the Virtual server name, and off we go? Did I miss anything? Thanks again.

Is this true? This does not work or this is not supported? Is anyone using flashbackup on win clusters? It's absolutely false - it does work and we use it a lot on clusters with far more than 5TB of data. You need to create a snapshot volume and you MUST add this to the cluster group with the data volume. Then use the cluster virtual server name that contains these volume to do the backup. So far I have broken these jobs down into multiple streams and that has bought me some ground, but I suspect the real issue here is the millions of files being parsed. I have also balanced to jobs across two media servers. Does anyone have any insights or opinions as to how I may be able to speed up these jobs. We found roughly a 2x performance increase using FlashBackup although I haven't benchmarked it in several years. Not only that, but the CPU hit on the client is considerably reduced from walking the file systems. 64-bit clients really, really help. One thing to watch out for is the maximum job on the client. Because you're using virtual server names, you may end up running multiple jobs on the same physical server. Although I've complained to Symantec many times about this, they have yet to give us any ability to control the number of jobs you can run. What I do is dedicate a DSSU to the cluster for the large data volumes and set the limit to 1. It ensures that only job runs in the cluster but my admins whine like you wouldn't believe if I kick off 2 jobs on the same node. There's currently no way to ensure that only 1 job can run per node in your cluster. This is one of the reasons why I have claimed - and continue to claim - that NetBackup doesn't really support clusters. It tolerates them but real cluster support isn't there yet. .../Ed ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

Re: [Veritas-bu] RMAN and MS-SQL Backup Fail - Error 21
I had a issue similar but also showed the occasional status 25. Turned out it was Mcafee Anti Virus. Particular attention should be paid to the Mini Firewall drive as noted in workarounds point 3. If you have upgraded VSE version you will need to rename/delete the file again http://seer.entsupport.symantec.com/docs/295599.htm also I put the master and medias ip in each others host file for good messure.

I've got the oddest issue I've been working two weeks. Two weekends ago my RMAN and MS-SQL backups began failing with errors 21. The jobs don't fail right away, and not every job fails. An RMAN job might write none or all but one of its datasets than fail with Status 21 - Socket Open Error. Re-runs are generally successful. I'd say about 30% of all RMAN and MS-SQL backups are failing with this nightly, and its not always the same database or dataset. I moved the jobs from a media server to the master, and the issue still occurs leading me to believe this is a master server issue. I've had a case open with Symantec all week and they are definitely seeing errors when the Master goes to open communications with the client to start the backup, but cannot determine why (so far.) Has anyone else ever run into this / have any ideas? I'm neck deep in Windows registry at this point trying to figure something out but I've got no joy so far. I've goggled and checked Symantec's site but this doesn't seem to be a common issue. -Jonathan ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

[Veritas-bu] Media servers on MSCS clusters
Good day I need a little clarification on some licensing. If I remember correctly the shared storage option and the openstorage option used to be both enclosed in one option, this being openstorage correct? I am reviewing how SAN media servers might be installed into a clustered environment. Specifically the Enhanced media server configuration. On Page 115-116 of the high availability guide. ftp://exftpp.symantec.com/pub/support/products/NetBackup_Enterprise_Serv er/290237.pdf The last bullet in the installation prerequisites state that the openstorage option is require for backup to tape. This would use the shared storage option for tape would it not? This would make more sense to me if this is a typo left over from old documentation. The usage here is to have a san media server not being failed over ( stand alone) on both nodes of a mscs cluster but running the backup policy via the cluster virtual name, the tape drives and disk Storage units would also be mapped to this Virtual name. Has anyone used a configuration such as this? What are people's opinions on backing up (multi TB) clustered environments? Any insight would be greatly appreciated Thanks SSS Sean Spellacy Senior Technical Analyst, IMIT, Backup and AntiVirus Vancouver Island Health Authority ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

[Veritas-bu] Master server...Hardware migration
Greetings good people. Long time lurker, first time caller so to speak. So thanks in advance Currently running 2 x NBU master domains(prod,nonprod). Both NBU 6.5.2 on 2k3 x64 enterprise in a master/media active/passive MSCS clusters. There is the need however to do some hardware juggling. The plan in a nutshell is: -To migrate the few nonprod clients onto the prod. -Recycle the non prod cluster into stand alone media servers for prod. Nonprod DBs can be lost. -Create a new active/passive master server cluster on new hardware. -Restore hot DB bak to new hardware with old shutdown (rollback) -Recycle old prod hardware to media servers prod. -Rebuild nonprod next fiscal maybe (new test environment). My question is regarding the taboo regarding changing host names for master servers. Since I am running NBU as a clustered app do I only need to keep the Netbackup virtual server name the same in my master move? Do the actual node host names of the cluster affect Netbackup? And of course Am I missing anything else or are there any gotchas I should be made aware of? Still pretty new to NBU so your comments, insights and suggestions are welcomed.
