Personal opinion of article - Mere speculation based on LinkedIn, job adverts and theorizing (next to last paragraph includes "appear to be", "failure of some sort", "seems apparent though"). So far, Hitachi, Oracle and Sun have been 'accused' of being the source of the problem...not Microsoft or Danger. A perfect combination of blamestorming and terrible "journalism".
Professional opinion of article/event - Way too much speculation, but there are two issues that we all need to keep in mind... 1) Always test upgrades/changes in a production-mirror environment. I recall a processor upgrade that had to be rolled back because of an incompatibility with the underlying operating system. 2) Always have a plan to return to a known good state without data loss. This includes having a known good backup (the only way to know this is to have performed a successful recovery) and capturing any data as it flows to the new system so it can be applied to the restored backup in case it has to be rolled back.

"On this reading the Oracle RAC was fed garbage by the Sun servers corrupted during an update process, and this fouled up access to the data." I wonder if they were using OCFS/OCFS2 on those linux servers. Doing an OCFS upgrade several years ago, we lost all our drive information. The data was still on the SAN mind you, but for whatever reason we could no longer get to it. The host servers didn't see the partitions any longer after the upgrade to OCFS and we had to remount the partitions and reload from backup. It was a very strange experience to say the least. */Chris Taylor/**Sr. Oracle DBA* Ingram Barge Company Nashville, TN 37205 Office: 615-517-3355 Cell: 615-354-4799 Email: chris.taylor@xxxxxxxxxxxxxxx <mailto:chris.taylor@xxxxxxxxxxxxxxx>*CONFIDENTIALITY NOTICE**: This e-mail and any attachments are confidential and may also be privileged.
