Network protocol error (39)

[Irina_Bobrova]

Hello! 

We have NBU 7.0, windows 2003 master server, rhel media server, media server with HP-UX 11.31 and two tape libraries.

Master server and rhel media server work normaly.

But anytime I try to add tape library (no matter manualy or using the wizard) to HP-UX media server I get the following message: "Cannot connect to oprd"  "Network Protocol Error (39)"

Can somebody help me?

you need to check connectivity between 2 host run below from master server & post o/p

/usr/openv/netbackup/bin/admincmd#>./bptestbpcd -client <client_hostname> -verbose

also make sure that you enter hostname entry in /etc/hosts with FQDN. 

But anytime I try to add tape library -- was it worked before ?? or you tring to implement new media server ?

[Irina_Bobrova]

When I execute this comand 

bptestbpcd -client <client_hostname> -verbose

output seems to be ok:

C:\Program Files\Veritas\NetBackup\bin\admincmd>bptestbpcd.exe -client media-server-name

-verbose

PEER_NAME = master-server.full.domain.name

HOST_NAME = media-server-name

CLIENT_NAME = media-server-name

PLATFORM = hpia11.31

PATCH_VERSION = 7.0.0.0

MASTER_SERVER = master-server.full.domain.name

EMM_SERVER = master-server.full.domain.name

1.2.3.4:3031 -> 5.6.7.8:13724

I've also checked entries in hosts files, everything looks normally.

This library works perfectly with other media server, but didn't ever work with HP-UX media server.  Yes, I'm trying to implement new media server.

Please check comms at PBX level:

On master, run :

nbemmcmd -listhosts -verbose

nbemmcmd -getemmserver

Yes, I'm trying to implement new media server. ---   I hope you followed below steps.

1. Need to zonning all existing devices with new HP-UX host.

2. Need to check tape drives visibility on OS level.

3. Install NBU media server on HP-UX host. (with proper licencing).

4. Perform device configuration wizard for new HP-UX host.

5. Create test file level backup.

We did everything according the instructions in NetBackup_DeviceConfig_Guide and NetBackup_AdminGuide.

Our HP-UX can see both tape libraries and their drives. There is one strange thing: other hosts can see two pathes for each tape library and drive, but for HP-UX server threre is only one visible path for each tape library and drive.

I've also checked licenses and there are proper licenses for media servers and shared storage, so I suppose there shouldn't be any problems...

File level backups using master server as media server run normally.

[Marianne]

The ONLY difference that I see here is that the master and linux media server are using shortname for master server but the HP-UX server is using FQDN for master.

I have learned that if FQDN is used anywhere, it needs to be used everywhere for PBX comms. Either change the HP-UX server to use shortname for master, or add aliases everywhere for FQDN, even in master server hosts file for itself.

[Irina_Bobrova]

I don't know how to change EMM Server for this host.

I've tried to add FQDN for my master server in hosts but it had no effect. 

[Yogesh9881]

Dont make any changes in EMM

Just put FQDN in ....

1. host file in Master server

2. Host file in HP-UX Media server

3. /usr/openv/netbackup/bp.conf  in HP-UX media server
