Should cluster be shutdown for network loss

Greetings,

My networking people want to schedule time to make a change to the netwotk that will result is network connectivity loss (routing) for a couple of minutes. Nothing with regards to IPs, gateways, etc will change. So my question is should I shut down the cluster for this or will it be OK? I would think only the applications (Oracle databases) should be shut down.

We're a 5 ES45 node cluster V5.1B PK5 on Memory Channel.

Thanks,
Vic

Hi Vic,

As you have a memory channel cluster, that should make everything independant of the network, so no you shouldn't need to shut down the cluster.

You'll probably also get away without shutting down the databases.

Cheers,

Re: Should cluster be shutdown for network loss

TRU cluster does not care about corporate network.
It must have cluster interconnect up and running.
Since you have Memory Channel, you do not have to worry. Even if you had independent network switch for ethernet cluster interconnect, it would be OK.
