Modular and Legacy

[Danny Petterson - DK]

Hi Gurus!

Is it possible to run a mixture of legacy and modular packages in a ServiceGuard Cluster (11.18 and 11.19)?

Thanks in advance.

Kind regards
Danny Petterson

Hm - I did find some other posts, the shows that coexistence is possible. However, I need an official HP-document which states this. Any ideas anyone?

Thsnks

it certainly is possible.
This is to allow exisiting clusters to migrate up to A.11.18 or A.11.19, and still use Legacy packages, while perhaps configuring new packages as Modular.
There is also a cmmigratepkg to allow you to migrate exisiting Legacy packages to Modular at your leisure.

There is no restriction for operating both legacy and modular packages simultaneously in either the Managing Serviceguard manual or the cmmakepkg command.

Including A.11.20 (the current version of Serviceguard), the product supports
both package formats in simultaneous operation.

I also created an document with his same text. If you need a copy, and have a software support agreement with HP, please open a software case and request document mmr_na-0283344. NOTE: the document ID will change when it is published for public viewing in the ITRC database.
The title of the document is:
HPUX Serviceguard - Mixing legacy and modular packages is possible

Ah - thanks a lot - any links about documentation for this?

And while we are at it - is it possible to use the standard migrate-procedure/ommands to migrate a legacy-package using NFS toolkit and SAP toolkit, to a modular package?

Thanks in advance.

Yours
Danny

First of all, take a read of this:
http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c02056215/c02056215.pdf

Then you need to verify which version of the NFS and SGeSAP toolkits support Modular packages

[melvyn burnard]

For SGeSAP modular support, you need a minimum of the version 5.0 Toolkit:

For NFS Tolkit, you need A.11.31.05:

You do not migrate toolkit packages from legacy to modular you rebuild the package using the newer modular toolkit for the application.

IN the ServiceGuard training course we teach both modular and legacy packages and they coexist in the cluster.

You can look at the cmmakepkg command man page to see that either can be created.

Thank you very much.
