Ed,

 

Curious to know what issues/what type of clusters you had trouble with?  What method were you using?  We generally use http and have updated clients in a application cluster without any issues.

Is anyone using this to upgrade client agents.  All things I've seen/read are negative about the product.  We wasted many hours trying to get it to work on version 6.5 when it first came out.  6.5.3 is supposed to fix some issues, I don't want to go down the LU road again without the possibility of success!  Anyone have it up and running successfully?


There are many caveats to getting this going properly and some are severe enough that we're not able to implement it for us for some of the clients.  We had a lengthy discussion with the developers of the client deployment packages at the last Symantec Tech Day in December so they're aware of the restrictions.

One of the biggest gotchas for us is that it's pretty much unusable in a cluster environment.  One of its checks is to see if the client is actually doing a backup before it tries to upgrade itself.  If you have multiple names for your hosts - and this is the case for close to 100% of the cluster users - this check can fail and your backup and/or upgrade job will fail.

In general, the NetBackup support for cluster clients is pretty poor.  Yeah, Symantec has hacked "support" in there but it's simply the case of not breaking in a cluster but that's about it.  LiveUpdate is just another example of where Symantec's cluster "support" fails to solve the problems properly.
