13 Disaster recovery

This section details the VLS disaster recovery procedures. It is comprised of the following topics:

• Recovering from a node RAID volume failure

• Recovering from operating system failure
Recovering from a node RAID volume failure
To recover from a node RAID volume failure, which occurs when both node hard drives fail:

drive configurations, and administrative and network settings (including the VLS serial number and
persistent FC port WWPNs).
To restore the virtual library and network settings from the configuration file:
1.
Set the network settings so you can open a Command View VLS session. See
