I have Data Protection Manager 2007 on a HP DL180 G5. For DPM storage we started with a RAID 5 array (3 physical disks, 1 logical) using the E200 Smart Array Controller. That filled up and we need more short term retention so I added another 3 disks (same model, size, etc) to the array and then expanded the size of the original logical drive using the "capacity expansion" feature in HP's Array Configuration Utility (v18.104.22.168). It took forever to complete (went from about 1.4TB to 3.5TB) but finally the Array configuration utility shows the array as healthy with a capacity of 3.5TB. Unfortunately, Windows (Server 2003 Standard SP2 x64) and DPM still only see the disk as 1.4TB. The data is all still there, which is great, but I need to get the OS and them DPM to recognize the additional freespace. The little documentation I could find on the E200 says the only change the system should see is the increased freespace. Ive rebooted and rescanned disks with no luck. Any ideas?
