EISA and the DPM storage pool

  • Artikkeli

I found this newsgroup thread interesting because I learned about something new to me, EISA partitions.

The issue was not being able to add a disk to the DPM storage pool. The clue was that on the disk is a 55 MB "EISA Configuration" partition. The resolution is that a disk with an EISA partition cannot be in the storage pool because when you add a disk to the storage pool, it becomes DPM's -- it's converted to dynamic if it isn't dynamic already, and DPM uses the entire disk. As Karandeep posted, "DPM would not and cannot overwrite OEM partitions as that may contain important data."

The learning part for me was...what is an EISA partition? I had never heard of it before. In an Automated Deployment Services (ADS) Knowledge Base article, I found out "Some original equipment manufacturers (OEMs) include a diagnostic partition that is installed from media that they provide. The diagnostic partition may also be named the OEM partition, or the Eisa partition."

So now we all know (and the next set of documentation will mention!), EISA partitions must be removed from disks before you can add the disk to the DPM storage pool.
