5020 Appliance - Optimized Duplication - Media Open Error 83
I have a site where we have implemented 4 x 5020 appliances, each configured as a seperate device (no multi-node storage pools). Site is NBU 7104, with the appliances all at 1.4.2.
There is 1 master and four media servers, and the appliances have been configured as follows:
Media servers 30, 32 & 33 are on Primary Site, media server 34 on DR site.
Appliance 1 (Primary site) - Storage server configured as attached to media server 32, with media server 30 & 33 as additional 'helping' servers.
Appliance 2 (Primary site) - Storage server configured as attached to media server 32, with media server 30 & 33 as additional 'helping' servers.
Appliance 3 (DR site) - Storage server configured as attached to media server 32, with media server 30 & 33 & 34 as additional 'helping' servers.
Appliance 4 (DR site) - Storage server configured as attached to media server 32, with media server 30 & 33 & 34 as additional 'helping' servers.
Disk pools were configured and storage units created. For the storage units, one was created with 'use any available media server', and then one was created for each of the media servers 30, 32, 33 - with only that media server being selected.
I am running a job which backs up 8.5GB of data to Appliance 1, using the storage unit specific to media server 30. The next step of the SLP does a Duplicate, specifying the storage unit which has Appliance 3 and only media server 30 specified. The backup step runs then I get the following error:

media open error(83)=
I see many references to this error in the forums, but am unsure as to how to proceed. One items points to licensing - we have an overall site license (1 for NBU and 1 for De-Dup). Both are entered, with the de-dup license also being entered on each appliance.
The main issue appears to point to both storage units (appliances / disk pools) being available to a single media server. In my case I am running the backup and the diplication to storage units tied to the same media server - media server 30. I do notice in the output above that the host ie-bcsadm034 is being noted on the bpduplicate statement - this is the media server at the DR site and it is specified as an alternate read server for this SLP.
Is my issue the Alternate read server - do I need ay reference to this at all ?
I expect to have media server 30 doing accessing boththe source and target appliances for this duplication, so why is media server 34 getting involved ? Is it down to the alternate read server being specified ?
Any input appreciated.

If you feel that the alternate read server is an issue in the duplication then leave it out or use the "any available" one.
The opt-dupe actually goes straight from appliance to appliance and never passes anything through a media server so all you need for a duplication is enough to trigger the duplication itself.
Other than that make sure all appliances can communicate with each other as that is the most important thing, especially across site, so use hosts file entries on the appliances if neccessary - very important if they have more than one network connected as they could route along the wrong network.
So all 4 appliances need to be able communicate with each other via the appropriate IP address
Hope this helps
