This will be the posts focused on using Data Protection Manager with Tape Library Sharing
For Data Protection Manager to be able to use library sharing the Tape Library and the Backup Servers needs to be connected though Fiber Channel , no other data paths are supported
One other option is to use partitioning so one Library can be sliced up into mutiple devices , this will from a Data Protection Manager standpoint be treated as a standalone installation
The install here follow the reference documentation from http://technet.microsoft.com/en-us/library/hh758124.aspx but adding the steps to get the fabric configured
Call me old fashioned but i really still like Tape as long term retention , sharing the library will help keep cost down as we can use larger library
In this example we have 2 servers DPM01 and DPM02 , DPM01 will act as library server and DPM02 will act as library client.
Prereq : DPM01 and DPM02 are booting off the SAN in this example so their Alias and Zoning against the storage have already been completed
The servers have no library or tapes connected
From a Fabric point of view we login to our switch and create a “New Alias”
To keep things simple we create a Alias called Tape
On our list of world wide names we select the two tape drives in the library and “Add Member”
After creating the Alias we need to create a Zone that will enable access from the Library Servers to the Library.
So Zone – > New Zone
On the newly created Zone we add the Tape Alias and the DPM01 and DPM02 server
The two Alias for DPM01 and DPM02 was created the same way as the Tape , create Alias select WWN
After creating the Zone and Alias we need to enable the Zone Config , select DPMTAPE and Add Member
And to enable the Zone select “Enable Config” this will commit the changes and make the Libarary available for the two servers
And then its time to install drivers on both nodes.
For larger production workloads its recommended to have a dedicated server for handling the Library
On all other servers the Media Changer needs to be disabled
So in this environment the Media Changer on DPM02 must be disabled from the device manager
