How to rebuild a node if one fails

Hi All,

I have a 2-node cluster connected to a Fiber SAN running NW SBS 6.5 SP5
with Cluster Services 1.8.02 and GW 6.5 SP6.

I can not find any documents describing how to rebuild a node if one
node fails (i.e. catastrophic failure)

Can anyone show me how to backup and restore the cluster without using
iManager?

Thanks in advance,

Ken

Re: How to rebuild a node if one fails

We use Portlock storage manager to take an image of the servers, so
that in the event of a failure of the type you mention, we can get
back working ASAP.

Re: How to rebuild a node if one fails


catastrophic failure of the server? its local drives? of the SAN?

Its local drive. I mean one node fails.

Thanks

I will try Portlock storage manager.

Thanks for your reply

Re: How to rebuild a node if one fails

If you need to do a rebuild and the server in question is only part of a
cluster, you can completely blow it away (uninstall NDS on server first,
then delete all references to it from your tree), rebuild it and reinstall
cluster services onto it.

It will probably clear up any other existing issues you have on that server.

I know people swear by portlock, but I've only had problems with it. Instead
of spending your time and money in getting it to work, just do a rebuild,
it's loads quicker.

Re: How to rebuild a node if one fails


phil's post is what i do. in a cluster, a server is just a host for
shared resources. it has nothing special about it - or at least
shouldn't. if you're really concerned about local drives, boot the
server from the SAN.

Re: How to rebuild a node if one fails


while i haven't had a (many) problem with portlock and I like it. I do
prefer the "blow away the node and reinstall" method - though having an
image to reinstall from helps the process along even more quickly...

Yes, but many people don't find it takes time to get it to work. It would
be interesting to know if there was something about your setup that SM
trips over, or if there's a problem in the instructions.

Perhaps you could explain more about your setup and the problems you've
had. I know this isn't a Portlock forum, but maybe we can get some
consensus about when and when not Portlock works. (That's a bad phrase,
but it will take me a while to figure out a better one. Especially on a
Monday.)
