Editing Host file on Netbackup 5520 appliance
I could do with some help on what options are available to add entries to the host file on the 5520 appliance. I am familiar with using the CLISH and navigating to >>Network from the main menuand the using the following command: hosts add 10.0.0.1 nbutest.nbappliance.lab nbutest host show - will provide an output of information in the file. Is there anyway to access the the host file by going through Support>>Maintenance(Enter Password)>>Elevate I believe you can drop in to the normal Linux directory structure and navigate to \usr\openv\netbackup... But where is the host file located and what is is called since most Linux articles seem to refer to \etc\hosts I have tried to use vi and view the hosts & hosts.conf files located in the \usr\openv\netbackup\bin directories, but they do not seem to list the same info as what I see when running hosts show through CLISH. Any assistance would be appreciated with the above. Thanks In Advance9.1KViews0likes3CommentsAfter upgrading appliance to 2.6.0.2 , backups fail intermittantly with error 24 and 14
Hi All, We recently upgraded on of our appliance from 2.5.3 to 2.6.0.2. It was a direct upgrade to 2.6.0.2 version. Since the upgrade backups are failing with error 24 and 14 mainly socket errors and we can see winsock error 10060 in bpbkar. The interesting thing is if we move the backups to the appliance which is not yet upgraded to 2.6.0.2 and is still at 2.5.3 level, the backup goes on fine. We have opened a case with Symantec and are still struggling for more than a week. Anyone of you had similar issues after upgrade. Kindly share and advise.Solved4.7KViews2likes36CommentsNBU appliance 5220 - access to script output

A quick question about using NetBackup with compressed SQL Server backups. Our backups infrastructure consists of NetBackup v7.6 and NetBackup 5230 appliances. Our SQL server estate is a mixture of SQL Server versions 2005-2012 on Windows 2003-2012. We've noticed that the deduplication ratio (as reported by backup jobs in Netbackup Activity Monitor) for compressed SQL backups is 0% (we experimented with the NetBackup SQL Agent and alsostandard flat file backups). Now we weren't expecting to get much deduplication out of a compressed SQL Server backup - but it was a suprise to get nothing at all. Previous tests performed on other deduplication platforms(Exagrid and Windows native 2012 deduplication) showed that a noticeable (albeit muchlower rate compared with uncompressed backups)deduplication level of about4:1 was possible withcompressed SQL Server backups. So my question is - is this a configuration issue on our NetBackup infrastructure - or is there a technical\designreason why thededuplication of compressed SQL Server backups is not available inNetBackup?

Hello, Having a little trouble getting 802.3ad nic teaming working on two 5230 appliances. I've configured teaming before on Windows 2008 servers and it seems to work fine. The network team configures LACP on the switch side, and on the server side, I create the team in 802.3ad mode. On the appliance however, I create the bond, and on cli as well as through the web interface of the appliance, it looks to be created and functional, but on the switch side it doesn't look to be active. The bond has been created with eth1,2 and 3 ports (1 Gb/s). The web interface shows them all as up, and the network configuration shows the correct IP on bond0(eth1,eth2,eth3) with bond mode at 802.3ad. On the switch side, for some reason, the bond automatically splits into 2 separate bonds, 1 bond with eth1 and the other with eth2 and eth3. Both bonds show with LACP configured. We have two identical appliances, and we have tried configuring bonding on both appliances and the exact same thing happens. Has anyone come across this, or have any suggestions of what else to check? Thanks!Solved4.3KViews2likes8CommentsHOW TO - configure a SAN based Tape Drive and Libr on a 5220 Appliance
Hello Techies, Could someone please provide a step by step guide on how to configure a SAN based Tape Drive and Libr on a 5220 Appliance configured as a Media Server to a traditional Master Server. NBU v7.5 5220 -v2.5 I understand that zoning of tape drive and libr is required but how to go about selecting the HBA port and locating a WWPN from the appliance to zone and the following steps. thank you to those who reply. -ESMSolved3.9KViews2likes3CommentsNBU 5220 Performance
We recently deployed a 5220 appliance into our environment as it was to be the savior in our battle against a backup window we were no longer able to meet. When we finally got it online and into our NBU environment the initial performance was great. The area we were to most benefit was with VMware backups. The data stores mounted directly to the appliance would allow direct access to the snapshots for a fast and efficient backup. Before this, we were performing client side backups so the impact on the hosts every night was significant as we tried backing up 600+ vms. The plan was to be able to move all Dev and test off-host backups to the middle of the day as the performance impact was minimal and the end result was an increased window to complete things. As we started with noon-time backups deduplication rates were high and so were the speeds. However, this performance gain was short lived, as we began increasing the load we suddenly saw performance drop to a point of concern. Backups were no longer speedy, 3500KB per second to 10,000KB. There are some that might pop to 24,000KB, but in a sample size of 15 as I write this, only one is showing 24,000. Now, I do have a few ideas. 1. We have a 72TB appliance, therefore, 2 disk trays, during the backups, the one disk tray is going crazy, all the lights are flashing and you can really see that it is working. However, the second tray is doing nothing. While you might see a blink here or there, it is almost nothing compared to the other disk tray. Is this to be expected? When we looked at the disk configuration, it shows concat, is this normal? 2. Too much data at once and we are simply burying the appliance. In reality, what sort of performance should I be able to expect from the appliance? 3. Relating to number 2, since we only have the one appliance right now while we wait to get the remote appliance in place, we are duping off to tape. This is running at the same time as a backup, so this means at the same time the appliance is writing a lot of data, it is also reading it back to tape. 4. We are overloading the data store so that read speed is bad from source to destination. We have fewer hosts,therefore, if we limit the jobs per host we limit the number of machines backing up at once (obviously). This means that backups take way long, so we removed the limit per host and just set a limit per data store. As we are new to it all, I am not sure what impact where, but again, I am trying to list any and all ideas from the start. 5. The appliance does not support multi-pathing, therefore, we only have a single path to the disk. Beyond that I am not sure, but this is something that doesnt help with the showcasing of the appliances to management at the moment. However, given the initial performance I am confident we can get back there.Solved3.2KViews4likes50Comments
