Of Disks and Disruptions

We use a Novell Netware Cluster for our file services. We established this cluster approximately 2 years ago. It's been a good network network citizen, quietly doing it's job day in and day out. It's grown from one  400gb partition to multiple ones adding up to about 4TB. the only disruptions we've seen were either due to power interruptions (UPS failed,) or SAN issues. One of the things we've found over the last two years is that if your SAN admin moves the data from one disk group to another , you can NOT move it at 100%,This is a "quirk" with the  the IBM SVC, if you move the disk group at any other speed besides 100%, it's fine.
