While performing duplication task by optimize copy (from old storage to new storage), duplication jobs are failing with error code 84 - media write error. Checked connectivity of media servers and both the storage but did not found any issue. Can you advice do I have need to perform / check anything before optimize copy duplication

 

Command used with bpduplicate
./bpduplicate -cn 1 -number_copies 1 -dstunit dstunit -dp dstpool -backupid image_ID

Tell us more about your source and destination Storage Units - what type of STU's?

We see this error:

 error 2060026 invalid server name

Did you add SERVER entries for one another on the 2 media servers?

Do bptestbpcd in both directions between the 2 media servers - ensure bpcd log folder exists on both for troubleshooting.

2 media server - e.g media01 / media02
2 storage server i.e disk Storage configured by OST (not as basic disk) - names removed from above logs.
Both the storage servers are connected with media servers (media01/media02)
STU's type - Disk pool at both storage server.

Was unable to find much about error 2060026 invalid server name so just confirmed - Storage Server names are mentioned correctly, host file is updated with both Storage servers on both media servers

SERVER enteries you mean, host properties of media server -> server enteries ?

OST storage from the same vendor?

Yes, I mean Server entries in Host Properties of both media servers.

If this is not the issue, ensure that you have all of the following logs on both media servers:

bpcd
bpbrm
bptm
bpdm

Yes, OST storage is from same Vendor. Added server entries in Host Properties

I have initiated duplication job from media01 only and got the same result. I checked but unable to find anything unusual in logs.

Attached reference logs. bpbrm and bptm has no logs.

What's your Netbackup version?

Assume your storage server is not the same as your media server...

media01 --> stsvr1

media02 --> stsvr2

media01 can talk to both stsvr1 & stsvr2, so does media02. But can stsvr1 & stsvr2 ping each other?

Check this technote as well: http://www.symantec.com/docs/TECH197523

Master server: NetBackup 6.5.6 (AIX)

Media server 01/02: NetBackup 6.5.6 (Linux)

media01 can talk to both stsvr1 & stsvr2 so does media02 and checked, stsvr1 & stsvr2 can ping each other.

In the storage server setting, did you choose media01 or media02 or both? Try to set it differently and see how it ends up.

Btw, 6.5.6 is already end of support, if you're going to get support please ensure you upgrade to version 7.x, this will also eliminate any known issue as in older version.

On storage servers setting is for both media 01/02. Tried to reconfigured storage but no luck.

Yes I am aware about EOL but due to few legacy applications I need to continue with this version till applications are upgraded :(
