NBU 7.6.0.1 Cluster performance

Question

Dear Team,

I am recently join new company.

In this environment NBU 7.6.0.1 master server cluster configured and VMWare backup configured.

Master server OS: Windows 2008 R2

&nbsp;

I observed that:

bptestnetconn -a -s –H &lt;master server host name&gt;

Is showing many MISMATCH entry. (i.e.:)

RL: 10.160.3.72 -&gt; b01ws034400.zb.if.atcsg.net&nbsp; &nbsp;&nbsp;&nbsp;:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0 ms FAST (&lt; 5 sec) MISMATCH

RL:&nbsp; 0.0.0.0 -&gt; **LKUP FAIL**&nbsp;&nbsp;

Slow (&gt;5 sec) or/and failed forward lookups:

&nbsp;

Please guide me how to remove Mismatch entry from server.

And How to increase master server performance&nbsp;and remove unwanted entries.

Also How to check cluster setting in my environment?

I believe that 'bptestnetconn -v -a -s' only uses/checks/references the 'Server=' and 'MediaServer=' entries from bp.conf on&nbsp;Unix,&nbsp;or on&nbsp;Windows from the registry.

On both Unix and Windows the 'Server' and 'Media Server' entries can be managed from the NetBackup Admin Console, in the Master Server "Host Properties" (under "NetBackup Management"), and also for any Media Server in their "Host Properties" too. &nbsp;So, it's probably best to use the Admin Console to remove names no longer required - rather than manually editing bp.conf - and/or&nbsp;manually hacking the Windows registry.

Not sure how above is related to 'Cluster performance'?

Are these hostnames VMs that are backed up via VMware Intelligent Policies?

Hi Atharava13, this is quite a nice command for testing the speed of name resolution, which can be used on all NetBackup installations (master, media, client):

&gt; bptestnetconn -v -a -s

...it performs a forward and reverse lookup of all 'server' and 'media_server' name entries that are present within the configuration of the installed NetBackup instance.

.

Dear Marianne &amp; Sdo,

Thanks for reply.

bptestnetconnn I know and related out put provided on 1st mail.

In this out put some of the client, device is showing [MISMATCH] as below, that I want remove from server.

cdesvaac996nb.zb.if.atcsg.net :&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0 sec [MISMATCH] -&gt; a01lt-p03817.za.if.atcsg.net

&nbsp;

And run the report again.

2nd I am searching commend, those will provide netbackup enviroment helth, performance and any older un removed media, client issue (Connectivity or other).&nbsp;&nbsp; that will help me to resolve the issue before occured.

Regards,

Hi,

Also We have many media server iSCSI disk partition, for SLP backup.

And all SLP will started on Sat-Sunday, every week at-least one iSCSI will not down and backup will failed.

showing Disk storage down.

Is it any commend those I will check before Sat and ensure that all disk partition (Storage units) is working fine.

&nbsp;

Regards,

Atharava.

These commands can be used to check the state (up/down) of the storage servers, disk pools, and disk volumes:

&gt; nbdevquery -liststs -U

&gt; nbdevquery -listdp -U

&gt; nbdevquery -listdv -U -stype AdvancedDisk

&gt; nbdevquery -listdv -U -stype PureDisk

.

Re name resolution: &nbsp;Are you trying to tidy up the 'server' names on a master server? &nbsp;There appear to be a lot of name entries, and so this would appear to be a&nbsp;quite large/complex environment. &nbsp;It's very difficult to offer any advice re amending/changing names without knowing a lot more about the environment, and what it is you want to achieve?
