Powering off and on local and external storage systems

When you power off the local system, data for each external volume in the cache memory of the local system is written to the external volume.

You do not need to disconnect the external system when powering off only the local system. However, if you do disconnect the external system, when you power on the local system again, access is disabled to the external system until you reconnect the external system.

You must temporarily halt Universal Volume Manager operations before powering off external storage systems. When the systems are powered on, you can resume all operations.

Steps in the procedures of this topic must be followed in this order:

1. When you power off the local and external systems, the local system must be turned off first before the external system.
2. When you power on both systems, the external system must be turned on first before the local system.
