Part III. Online Storage

The Online Storage section covers how to set up and manage iSCSI and FCoE storage connections.

Online storage reconfiguration must be done carefully. System failures or interruptions during the process can lead to unexpected results. Red Hat advises that you reduce system load to the maximum extent possible during the change operations. This will reduce the chance of I/O errors, out-of-memory errors, or similar errors occurring in the midst of a configuration change. The following sections provide more specific guidelines regarding this.

In addition, Red Hat recommends that you back up all data before reconfiguring online storage.
