File Library and File Jukebox relocation in DP

Logical Device modifications

By executing the last step in the previous chapter, we have taken a backup of our host kiekeboe to a

local attached device. Imagine now we’d like to have this data onto tape media, but our host can’t

reach a tape device. To perform a copy-to-tape anyway without having to pass the data via the LAN

to another DP client who does see the tape drives, we will relocate our LUN’s with backup data upon

and “notify” DP of these changes.

Downloading the Existing Device Definitions

By executing the next series of commands we get our logical device definitions in ASCII format:

C:\Program Files\OmniBack\bin>omnidownload -device TransFL_Writer0 >c:\temp\FL0

C:\Program Files\OmniBack\bin>omnidownload -device TransFL_Writer1 >c:\temp\FL1

C:\Program Files\OmniBack\bin>omnidownload -library TransFL -file c:\temp\TransFL

C:\Program Files\OmniBack\bin>omnidownload -device TransJB_D1 >c:\temp\JB1

C:\Program Files\OmniBack\bin>omnidownload -device TransJB_D2 >c:\temp\JB2

C:\Program Files\OmniBack\bin>omnidownload -library TransJB -file c:\temp\transJB

The above created files must now be edited.

In each of them

HOST kiekeboe.company.com

Is changed into

HOST lminnaert.company.com

Uploading the Changed Device Definitions

To “notify” DP of these changes we need to upload them in our Media Management

database of DP.

C:\Program Files\OmniBack\bin>omniupload -modify_library TransFL -file C:\temp\TransFL

C:\Program Files\OmniBack\bin>omniupload -modify_library TransJB -file C:\temp\TransJB

C:\Program Files\OmniBack\bin>omniupload -modify_device TransFL_Writer0 -file

C:\temp\FL0

C:\Program Files\OmniBack\bin>omniupload -modify_device TransFL_Writer1 -file

C:\temp\FL1

C:\Program Files\OmniBack\bin>omniupload -modify_device TransJB_D1 -file C:\temp\JB1

C:\Program Files\OmniBack\bin>omniupload -modify_device TransJB_D2 -file C:\temp\JB2

LUN relocation

It goes without saying that the previous download and upload steps will be insufficient to get to a

working situation.

We have to create, of course, identical mountpoints on our host lminnaert as on kiekeboe and see

that the LUN’s previously attached to the host kiekeboe are now mapped on our host lminnaert who

will take care of performing the copy-to-tape.

After having done so, it’s always best to run a dummy test backup job to verify the proper functioning

of our “adjusted” device definition.
