Halt HA Package to add a filesystem?

[Bob Sobey]

Please clarify for me regarding the need to halt a package to add a new filesystem.

In our 11iv1 SGv16, With the package up, I can create and mount a new filesystem, add it to the package control file, send a copy to the other node, and I'm golden. No need to bring the package down.

To add a filesystem with 11iv3 SGv18 - I understand I need to bring the package down? In a dynamic enterprise HA environment, this seem rather appalling. Have we taken a step backwards, or am I missing something? I hope I'm mistaken. Thanks; Bob

per call with HP:
------------
A.11.16 works with legacy package control scripts. You can manually change the script, and while the package is running create a file system and mount it to a volume in a cluster VG. In A.11.18, you can do the same thing if it is a legacy package, but you cannot do it to a modular package and keep the package running.

Shalom,

To add a new file system for use in an existing package, you probably want to bring down the package.

The reason is you want to test whether the package is going to activate the volume group and mount the file system at start up.

Technically though you can create the file system on shared storage, mount it manually, configure the new volume group to not auto activate and boot without actual downtime.

So the reason answer is "It depends" It depends on how much risk you want to take.

I would think however, altering the package configuration and checking the package would be possible.

You should be able to add a new file system to a running package whether created with modular or legacy format.
Give it a try with a dummy package to verify for yourself.

However, modifying or removing a file system in a modular package will cause the package to halt and restart when you perform the cmapplyconf to update the cluster with the new detail.

thanks folks; we'll see. may even add filesystem mounts in the pkg .sh file ...
