Samba friends,
I work in Wal-Mart's IT department, specifically with Unix Servers of
various flavors, but HP-UX is predominant in our Home Office environment.
I recently built an two node HA cluster on HP 11.11 boxes. I want to be
able to have Samba use the virtual name of my cluster. Currently Samba is
configured to use the hardcoded box name, however if the box happens to go
down, we have to go in and reconfigure the clients to point to the secondary
box name. Sure would be nice to point everything to the virtual name. So I
was wondering if you have any documents that explain how you would go about
setting up Samba with HP's MC/Service Guard?
Thanks,
Dan Doffermyre

I believe that the HP Response Center has taken calls from Wal-Mart on CIFS/9000 Server (HP's supported version of Samba), so I think that at least some Wal-Mart sites are running CIFS/9000. In any case, CIFS/9000 Server has MCSG scripts (.cntl,.conf,.mon) in /opt/samba/HA/ under active_active or active_standby. In addition, there are detailed instructions on how to configure MCSG with the relocatable IP address and NetBIOS alias in the README file. The same instructions are available in the CIFS/9000 Server manual. You can get a copy of the manual at http://www.docs.hp.com/hpux/netcom/index.html#CIFS/9000. You can download CIFS/9000 Server for free from http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/displayProductInfo.pl?productNumber=B8725AA.

I didn't use HP's configuration. I installed Samba on both nodes, and used the smb.conf 'include' feature to include a bit of configuration file from a file in the cluster package, to refer to the share in the cluster package. On the node that the cluster package is not running, samba cannot find the 'included' file of course, but that doesn't bother Samba. You then get the clients to connect to the virtual (cluster) ip/name. This will work if you have Samba listening on all addresses, as is the default. Works fine, and you don't need to stop/start Samba when a package switches, so you don't bother all the other packages which may be using Samba at the same time. If you want more info, I'd be happy to oblige. Matt
Dan Check out the HP documentation for the most recent revision of the HP-UX implementation of Samba 2.2.x (referred to as CIFS/9000 Server) at: http://docs.hp.com/hpux/onlinedocs/B8725-90021/B8725-90021.html Chapter 6 is titled "Configuring HA CIFS/9000" and talks about the configurations recommended for integration with MC/ServiceGuard. HP provides scripts pre-packaged with this Samba implementation which is provided as part of HP-UX, or can be downloaded from: http://software.hp.com under "Network & Systems Management". Cheers John.
