Backup Restore Smarts after patching

Hallo there I am a newbie on this forum.

And we are running Smarts for not a long period of time. When we patch software ist normal to create a kind of backup

when something is wrong we like to revert to the old version.

I understood that creating a backup with using tar is not working because the patch inpacked the Installshield.

Unstalling en reinstalling the old pach cause that the special custmisations are lost. How to prevent this.

Please can some one help a simple procedure how to backup and restore  when a patch is not working correctly?

Greetings

Chris Alberts

Hi Chris,

just take a look on the pdf file which is provided as additional download to each patch.

There you will find how to install and even uninstall patches.

The binary smgetinfo is used to take backup of your current installation.

To uninstall a patch point to the appropriate _rpuninst folder and invoke the uninstaller but keep following in mind.

Uninstalling a patch removes all previously applied patches and returns the

EMC Ionix software to the baseline product version.

If you want to revert to a previous patch, you must:

◆

Uninstall the currently installed patch to return to the baseline version.

◆

Reinstall the previous patch.

For example, to revert from Patch 200 to Patch 198, you must uninstall Patch 200,

then reinstall Patch 198.

As a side note, it is rare but possible that the semantics of a given MODEL attribute might be changed.  To insulate yourself from those changes make sure that your domain manager startup includes the "--ignore-restore-errors" option.

WIthout that enabled, the system will complain in the logfile about a mismatch of definitions and then just stop.
