media open error  (83)

All the 7 media servers are with the same platform, each media server has 3 HBAs for FT services, and each HBA connected with 6-12 clients. Each client has 2-3 policy, and jobs run at the same time may reach up to 15 per media server. I noticed that during one backup period, 12 jobs are started in that media, only 3 successful started, others failed with status 83, the Devices-Media Servers-View FT Conncetions shows only 3 connections.

It's strange that the error occurs in random client, even one job failed with status 83, after an hour another job in the same client works fine.

Some configurations are as follows:

NetBackup Version: 7.1

OS(both media adn client): SUSE Linux Enterprise Server 10 (x86_64)

Storage Unit: VTL with 8 drivers, maximum streams per drive is set to 4

Maximum concurrent FT connections  12

NUMBER_DATA_BUFFERS  16

SIZE_DATA_BUFFERS  262144

# /usr/openv/netbackup/bin/admincmd/nbftconfig -getconfig

u nbumaster 2 4 preferred 5 5

Do you have NUMBER_DATA_BUFFERS_FT config file in place?

See http://www.symantec.com/docs/TECH71062

Yes, I have tried to create NUMBER_DATA_BUFFERS_FT with 8 and 12 and 16, and the error continue to occur. Right now I removed that file, I don't know whether I should try 32?

Are you select Limit job per policy in policy atttribute?

please unselect it or change the number to 15

Try NUMBER_DATA_BUFFERS_FT with value of 32.

The case that prompted TECH71062 was solved with value of 32.

I have tried NUMBER_DATA_BUFFERS_FT 32 (also reduce Number of FT pipes to 10 according to TECH62006) and the error still occurs

Maybe time to log a support call?
