NBU upgrade from 7.1.0.4 to 7.5.0.6

[FlyMountain]

We are planning to upgrade our NBU from 7.1.0.4 to 7.5.0.6 on HP UX IA64. I got a few questions which somebody may share your knowledge with us. Thanks.

Would like to know if any other tips.

1. the release notes say we will need to apply 7.5.0.6 immediately after 7.5 upgrade to avoid the metadata migration to initialize on 7.5. do we have to start all NBU services before we upgrade to 7.5? it looks if not, the upgrade process will automatically start some NBU services.

2. do we have to run the "metadata migration" manually or it will be kicked off automatically when we start services?

3. How about our archived catalog? do we have to restore all archived catalog back for this "metadata migration" to complete?

4. How long is going to take for "metadata migration" process for around 200,000 images?

Hi Felix, A few thoughts for you on this:

1) It is reccomended to upgrade to 7.5 then upgrade to 7.5.0.6 immediately before you bring up the services. There were some known issues with catalog import into the database at 7.5. As soon as you start the services it will attempt to import the catalog into the database

2) This process begins automatically after the services come back up.

3) Per the fix in 7.5.0.3:

1. Sites that have not yet upgraded to NetBackup 7.5 should wait until the release of NetBackup 7.5.0.3, then make the following adjustments to the upgrade procedure:

• During the 7.5GA installation, do not start NetBackup services.  This will prevent the image migration from initiating.
• Immediately after completing the 7.5GA installation, install the 7.5.0.3 maintenance release.
• After 7.5.0.3 is applied, NetBackup services can be started normally.  A correct image migration will proceed as a part of the initial startup.

4) I dont have a real world answer for you, but page 14 of the upgrade guide (found here: http://www.symantec.com/business/support/index?page=content&id=DOC5198) contains all the information to estimate the time it will take. I have found these estimations in the past to be a bit generous.

In addtion to above excellent post - the fix is especially for archived catalogs.

do we have to start all NBU services before we upgrade to 7.5?

No, you need to stop services before upgrade and not start after 7.5 installation.

Archived catalogs still have header files in normal image location. It is these header files that are migrated to EMM. So, no need to restore archived catalogs.

Please remember to run a catalog backup just before upgrade.

do i have to suspend the scheduling, all running jobs and stop all NBU services before the upgrade?

what is the recommendation from Symantec for these?

thanks,

Per the Installation guide (here: http://www.symantec.com/business/support/resources/sites/BUSINESS/content/live/DOCUMENTATION/5000/DOC5155/en_US/NetBackup7.5_Install_Win.pdf)

On Page 59, gives all the information on the install and lists the order of steps to take. I have followed these exactly and had no issue, but I have heard of others getting 'file in use' type errors that have had to shut down all NBU services to get those processes to release files, similar to this:

Hope this helps

Is recommended to apply all the patches before the image migration starts, but if you think when NBU 7.5 came out there where no patches and the upgrade worked, meaning if you fail to apply the patch and let the image migration happen, you will be fine, recommendation is to apply the patch because there are many bug fix between 75 and 7506 and is mainly to prevent a major issue during the upgrade, but if you ran the NBCC and everything was good, upgrade should be smooth.

Hope this helps.

Regards.

Hi everyone, thanks for all your input.

Is there any simple way to confirm if the "metadata migration" completed or not?

i kicked off the upgrade and looks the upgrade completed.

Phase1 starts when you start NBU services after upgrade, phase 2 starts after you run one of the commands:

On UNIX systems:
/usr/openv/netbackup/bin/admincmd/bpimage -cleanup
-allclients

On Windows systems:
install_path\NetBackup\bin\admincmd\bpimage -cleanup
-allclients
 

You can watch the process of the image clean-up job to complete (can view progress in the activity monitor portion of the admin console). Wait for status 0 completion (if not see page 21 of upgrade guide)

You can determine overall migration status with the following:

■ On UNIX systems:
/usr/openv/netbackup/bin/admincmd/nbemmcmd -listsettings
-brief -machinename masterservername

■ On Windows systems:
install_path\NetBackup\bin\admincmd\nbemmcmd -listsettings
-brief -machinename masterservername
If the result shows SLP_DSSU_MIGRATION_STATE="1", phase 1 has completed.
If the result shows SLP_DSSU_MIGRATION_STATE="0", phase 1 has not completed.
If the result shows LIST_FS_IMAGE_HEADERS = "0", phase 2 has completed.
If the result shows LIST_FS_IMAGE_HEADERS = "1" or if no result appears,
phase 2 has not completed.
