Lefthand 4500 - Cluster

JamesL — Fri, 26 Mar 2010 10:06:07 GMT

Hi
I had my first LH4500 1.8TB last year. Configured for Thin provision with 300GB and 1TB of volume space.
I recently add another LH4500 5.4TB. I added to the same management group and same cluster.
Looking at the "node use" tap in the cluster, i have 6.5TB RAW, Usable is ONLY 2.61TB. My second LH's usable space reads 1.3TB, same as my first LH.
How can i get the full capacity of the second LH? All are configured with RAID5.

THANKS!

The only way to get the full capacity from the 5.4T node in your situation is to remove it from the existing cluster, create a new cluster and add it to that new cluster. When adding storage modules to a cluster they should be of similar capacity and performance to get the best from them. A simple analogy would be adding physical disks to a RAID array on a Smart Array controller - if they have different capacities then all disks will operate at the capacity of the smallest.
