I have, on a few occasions, been puzzled as to how to downgrade NetWorker on Mac OS X. There’s a couple of distinct issues that I’ve come up against, and I thought I’d outline them here now that I’ve fully resolved how to do it.<\/p>\n

The first is that when NetWorker installs, it’s meant<\/em> to install uninstall utilities into \/Library\/Receipts\/NetWorker.pkg. However, on Snow Leopard, NetWorker doesn’t write this uninstall information, meaning that technically it’s not possible to uninstall the product. There is, thankfully, a way around this.<\/p>\n

First, open up your NetWorker.dmg file, but then drop into the command line and change directory into the NetWorker.pkg\/Contents directory within the dmg:<\/p>\n

\"Important<\/a><\/p>\n

<\/a>In the above screen shot, I’ve shown the two directories you need to be aware of; NetWorker.pkg\/Contents, and NetWorker.pkg\/Contents\/Resources.<\/p>\n

You’ll note in the Resources directory that there’s a NetWorkerUninstall script, which needs to be run as root. However<\/strong>, the script depends on there being some content in \/Library\/Receipts\/NetWorker.pkg, so you’ll need to do the following:<\/p>\n

$ sudo bash\n# cd \/Volumes\/NetWorker<<version>>\/NetWorker.pkg\/Contents\n# mkdir -p \/Library\/Receipts\/NetWorker.pkg\/Contents\n# cp Archive.bom \/Library\/Receipts\/NetWorker.pkg\/Contents\n# cp Resources\/NetWorkerUninstall \/Library\/Receipts\/NetWorker.pkg\n# \/Library\/Receipts\/NetWorker.pkg\/NetWorkerUninstall<\/pre>\n
Once you run the NetWorkerUninstall script, there’ll be a brief pause before you see a flash of lines with entries such as:<\/p>\n
Removing: \/usr\/share\/man\/man8\/tur.8<\/pre>\n
and so on.<\/p>\n
At the end of this, you theoretically should<\/em> be able to run the NetWorker installer for the version you want to install. However, you’re likely to still end up with the following output from the installer:<\/p>\n
\"NetWorker<\/a><\/p>\n
It was this step that had been frustrating me. Thankfully though, I finally started to think like a combined Mac + Unix user, and released there was probably a plist style file hanging around somewhere that wasn’t being cleaned up by the uninstaller, and that if it followed Apple’s naming conventions, it would be com.emc.*.plist. So I did:<\/p>\n
# find -xdev \/ -name \"com.emc.*\" -print<\/pre>\n
Lo and behold, I found the following:<\/p>\n
\/private\/var\/db\/receipts\/com.emc.networker.bom\n\/private\/var\/db\/receipts\/com.emc.networker.plist<\/pre>\n
Removing them was the final piece of the puzzle \u2013 without them hanging around, the NetWorker installer utility didn’t pick up there was a newer version of the software installed, and I was finally able to downgrade NetWorker for testing purposes.<\/p>\n","protected":false},"excerpt":{"rendered":"
