Unable to append tape with MTWEOFI enabled

HP Data Protector

I’ve observed the following issue on Media Agents on Linux with MTWEOFI support turned on in omnirc (to optimize performance) when running recent versions of Data Protector such as A.09.09_116. While the first write operation to a blank or expired media will succeed an append operation to a tape by the Linux Media Agent will generate …

Parallel operations executed on the same library changer device caused a subset of the operations to fail leading to aborted sessions. A Linux Media Agent controlling the library changer reported the following error. [Normal] From: …

HP Data Protector

Starting with Data Protector A.09.05 Red Hat Enterprise Linux 7.0 and 7.1 is now a supported Cell Manager platform.

Clean up after Data Protector IDB restore

HP Data Protector

IDB restore with Data Protector 8 and later is really straight forward. It allows a much more granular recovery than in previous versions, since it’s done using a fully featured module instead of a file system hot-backup. You’re able to restore the IDB (PostgreSQL database) including log file recovery, DCBF files and configuration files individually or all together …

Data Protector Push installation for Debian clients

HP Data Protector

Integrating Debian or Debian-based Linux clients (e.g. Ubuntu) into a Data Protector cell could be a pain, if you have more than a bunch of them. Patch rollout and release upgrades will even take more time if you poke around with alien to convert the Data Protector rpm into deb format. There are some simple requirements …
