HP-UX WBEM Direct Attached Storage (DAS) Provider Release Notes (September 2013)

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.

The product has the following limitation:

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

• For disks having capacity more than 2TB (terrabyte), the “Capacity” field in the disk instance

output contains value as “Not Available”.
