The last I heard from Dell, they said they weren't going to fix this but focus on the next release. I haven't seen an 8.4 release, so as a work around, you'll have to uninstall OMSA 8.3 from all of your machines and then install it again from the repo. Huge PITA though. Other option is to reset your vCenter VUM database and don't add back in the Dell repo. Then you'll be able to scan your hosts w/o issue again. Thanks Dell!!!
I think I have found a bug. I create Custom ISOs for ESXi 6.0 so I can include the latest drivers and the VIBs for our storage. I created a new ISO with ESXi 6.0 Update 2 with the latest Dell OpenManage 8.3.0 VIB. In vCenter(6.0) Update Manager, I have the Dell repo as a download source: [URL] I downloaded the OpenManage 8.3.0 VIB from here:  <ADMIN NOTE: Broken link has been removed from this post by Dell> However, now when I run a scan of the host with Update Manager, it fails and the error in esxupdate.log:  2016-04-28T15:44:03Z esxupdate: esxupdate: ERROR: ValueError: Cannot merge VIBs Dell_bootbank_OpenManage_8.3.0.ESXi600-0000, Dell_bootbank_OpenManage_8.3.0.ESXi600-0000 with unequal payloads attributes: ([OpenManage: 7809.081 KB], [OpenManage: 7807.439 KB]) I'm seeing older version of OpenManage that had this same error and it was a bug. Things I have done: Reinitialize VUM database, which I can then scan the hosts successfully. Once I add back in the Dell repo, it starts failing again with the above error in the esxupdate.log file. Anyone else seeing the same thing?
