So. The next Zen will be the big focus of BS-07, most likely.
Here is more:

Please note that Open Enterprise Server services currently run on SUSE Linux Enterprise Server 9. New purchases of Open Enterprise Server will not include SUSE Linux Enterprise Server 10 until it officially becomes part of Open Enterprise Server in the next release, scheduled for mid-2007.Hmm. This tells me that what we'd be seeing at BrainShare '07 will be beta builds of OES2. March is not 'mid-2007'.
As I said, this is fairly simple to do through ZenWorks. Create a new Application Object and enter in the details manually. Put this on the "path to file"
Un-register Vgx.dll
On the topic of clusters, do you find the benefits of a cluster/SAN setup out weighed by the increased complication in node upgrades/patching and the "all your eggs in one basket" when it comes to storage on the SAN.One of the biggest things to get used to with clustering is that your uptimes for your cluster nodes will go down dramatically from what you're used to with your existing mainline servers, but your service uptimes will go up. Once we put in the cluster we haven't had an unplanned multi-hour outage that wasn't attributable to network issues. The key here is 'unplanned'. We've had several planned outages for both service-packing and actual hardware upgrades to the SAN array itself.
BENCHTEST-LIN:helpNote the bolded commands. Perhaps Novell has slipped in Shadow Volumes in a post-SP2 update? Doing help on the 'create shadow_volume' command gives this output:
change volume

create shadow_volume
create volume

mount
purge volume
remove volume

BENCHTEST-LIN:help create shadow_volumeand "help shadow"
NAME: create shadow_volume - Create NCP shadow volume
SYNTAX:
create shdadow_volume ncp_volume_name path
DESCRIPTION:
Use this command to create an association between an NCP volume
and a NCP shadow volume. This command only adds the NCP shadow
volume mount information to "/etc/opt/novell/ncpserv.conf".
This command can be added to a cluster load script.
You can run ncpcon console commands without entering NCPCON by
prefacing the command with ncpcon.
EXAMPLE:
create shadow_volume vol1 /home/shadows/vol1
BENCHTEST-LIN:help shadowYes, 'EXAMPLE:' is blank in the HELP. Hmmmmmm. I don't see any documentation updates, but those commands are indeed present. Richard Jones mentioned that shadow volumes are an OES2 feature, and to try it out in the beta. Perhaps there is an OES2 beta in the near future? Who knows.
