OTS 9000 in SG environment

[Paresh Parikh]

I have a sg pkg running with OTS configured using the physical IP of the server. I know there is a way to force an IP change when I failover to another node. (nsap ??) Does anyone know how I can failover my package and then change the IP for OTS on the failover server?
Thanks,
Paresh

Hi Paresh,

I have a sg pkg running with OTS configured using the physical IP of the server. I know there is a way to force an IP change when I failover to another node. (nsap ??) Does anyone know how I can failover my package and then change the IP for OTS on the failover server?

MS SG is designed to support packages which are vertual machines ( collection of applications and programmes ).
If you plan to use packages and applications so that in case of failover the applications switch to the alternate package,

So, your OTS application MUST use the virtual address of a package and not the physical address of a server.

and MS SG maps the package address on the server physical address on which it runs.

By this your OTS application will be MS SG compatible.

Good luck.

Hi Paresh,

If you are running OTS in a MC-SG cluster, then it must be running in a package. Are you trying to failover the OTS to the other node in the cluster?

I am attaching a MC-SG quick reference document.

If you are trying to failover to the other node, you can halt the package (cmhaltpkg) and start the package on the other node (cmrunpkg -n node2 pkgname). You can check what packages are configured using cmviewcl. All the cm* commands are in /usr/sbin.

-HTH

Oops,

Forgot to attach the document.
Here you go

I suggest you read the Managing MC/ServiceGuard manual at:
http://docs.hp.com/hpux/onlinedocs/B3936-90045/B3936-90045.html
and the particular section is Appendix F:
Using OTS/9000 on the LAN

extract:

MC/ServiceGuard supports OTS/9000, Hewlett-Packard's implementation of OSI Transport
Services and related protocols. To configure OTS/9000 with MC/ServiceGuard, perform the
following steps:

1.Configure OTS/9000 on all cluster nodes. See your OTS/9000 documentation for complete
information.

2.Configure an IP subnet for each LAN card that has OTS on it. This is needed because
MC/ServiceGuard actually monitors the LANICS (LAN interface cards) through configured
IP subnets. See Chapter 3 for information on specifying IP subnets in MC/ServiceGuard.
