Chapter 6: Volume Configuration 6-15
Example:
If you are working in
a V-Switch cluster,
this volume must be
configured on both
V-Switches.
In Figure 6-10, Simple Volume 5 and Simple Volume 12, both built over an
entire physical disk, are concatenated to create a concatenated volume,
Concat 1. Data is read/written first to Simple 5. When the data chunk
gets to the end of Simple 5, it continues with Simple 12 reflecting the
volume order as entered in the CLI command.
