[Veritas-bu] DataDomain Optimized Duplication Failures
2010-10-07 11:29:44
I'm having issues with Data Domain optimized duplication
and wondered if anyone here had seen any issues like this. I've got a case
with both Symantec and DataDomain but thought I'd check here too.
Environment:
NBU 7.0 on Linux RHEL5, Nine Windows 2008 R2 Media servers
(Master and Medias are all VMs)
DDOS 4.8.1.0, OST plug-in 2.2.1.1
Using SLPs and optimized duplication to control the replication
to a remote DDR
Here's what happens:
Anytime a duplication job kicks off with more than one
image to duplicate to the remote DDR, it will complete the first one and
fail on the next one with an 83 (media open error). A new job will then
kick off with the remaining images to be duplicated. The same thing will
happen where the first one completes and the remaining N images fail. Repeat
until all images in the list complete. If a dupe job with only one image
is spawned, that image will complete successfully.
For example: duplication job starts with 3 images. The
first image completes successfully, but the job then fails. Another duplication
is started with the 2 images that did not complete and the first image
of that list completes successfully and then fails again. A final job is
started with the last image and completes successfully (status 0). This
behavior is consistent regardless of the number of images in the list.
Here's a snippet of BPDM:
