HP-UX WBEM DAS (Direct Attached Storage) Provider Release Notes (766961-001, March 2014)

• Problem:

The events are lost when diagnostic products are upgraded on a DRD cloned disk.

Description:

Prior to September 2012 release version of diagnostics product, the postgres 7.4.2 version

was supported. However version 8.4.8 is shipped from September 2012 release. Due to the

missing data compatibility between PostgreSQL version 7.4.2 (prior to September 2012) and

8.4.8 (September 2012 release or later) when diagnostics products are upgraded from prior

to September 2012 release to September 2012 web release and later, the postgres data

need to be migrated to 8.4.8 format. Data migration involves backup in 7.4.2 version using

the pg_dumpall and restore in 8.4.8 version using the psql operations. Both of these operations

requires a running postgres service. But in the DRD environment there is a limitation that no

service can be run on the cloned disk when products are either installed or upgraded. This

limits diagnostics product upgrade steps from taking the backup of the postgres 7.4.2 data.

As a result, the data such as events and error records is lost during such circumstances.

Workaround:

You can select any of the following two alternatives:

1. To install the product on the DRD cloned disk as a normal upgrade scenario. The scenario

will be same as fresh installation and user may refer to event.log for historical event data.

2. To have a seamless migration of the data from postgres 7.4.2 version. In this case, the

user is required to perform the manual steps listed in the Installation scenarios of Postgres

8.4.8 guide at: www.hp.com/go/hpux-diagnostics-sfm-docs.

Limitations

The product has the following limitation:

• It is a read-only provider and hence does not allow users to modify, create, or delete instances.
