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: 1. Replace the failed node hard drives. See SATA hard drive. 2. Install the operating system on the new hard drives. a. Connect a keyboard to the keyboard connector. See Rear panel components. b. Connect a monitor to the video connector. See Rear panel components. c. Insert the VLS Quick Restore CD into the CD-ROM or DVD-CD drive. The VLS Quick Restore CD auto starts. d. Press R on the keyboard to start the re-installation of the operating system. The installation takes 30 minutes or less to complete. The screen may freeze for the last 10 minutes of the installation. This is normal. The VLS Quick Restore CD is ejected and the system reboots when the installation is complete. 3. Restore the configuration settings. See Restoring the configuration settings. 4. If one or more capacity licenses had been added to the VLS, re-install the VLS capacity license(s). See Re-installing the VLS capacity licenses. Restoring the configuration settings The VLS virtual library configuration and network settings can be quickly restored from the configuration file created by performing Saving configuration settings. See Restoring the virtual library configuration from a configuration file. If a configuration file was not created, you must reconfigure the network settings, and rebuild the virtual library and virtual drive configurations, and the VLS300 storage pool configurations (see the section called "Recreating the VLS300 storage pools". The cartridge configurations, however, do not have to be rebuilt, as they are stored on the disk arrays. See Rebuilding the virtual library configuration. Restoring the virtual library configuration from a configuration file Restoring the virtual library configuration from the configuration file restores the virtual library and virtual 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 Setting the network settings. 2. Open a Command View VLS session and log in as the administrator. See Opening a Command View VLS session from Command View TL. 3. Add all secondary nodes using the Add Node Wizard.

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:
1.
Replace the failed node hard drives. See
SATA hard drive
.
2.
Install the operating system on the new hard drives.
a.
Connect a keyboard to the keyboard connector. See
Rear panel components
.
b.
Connect a monitor to the video connector. See
Rear panel components
.
c.
Insert the VLS Quick Restore CD into the CD-ROM or DVD-CD drive.
The VLS Quick Restore CD auto starts.
d.
Press
R
on the keyboard to start the re-installation of the operating system.
The installation takes 30 minutes or less to complete. The screen may freeze for the last 10
minutes of the installation. This is normal.
The VLS Quick Restore CD is ejected and the system reboots when the installation is complete.
3.
Restore the con
fi
guration settings. See
Restoring the con
fi
guration settings
.
4.
If one or more capacity licenses had been added to the VLS, re-install the VLS capacity license(s).
See
Re-installing the VLS capacity licenses
.
Restoring the con
fi
guration settings
The VLS virtual library con
fi
guration and network settings can be quickly restored from the con
fi
guration
fi
le created by performing
Saving con
fi
guration settings
. See
Restoring the virtual library con
fi
guration
from a con
fi
guration
fi
le
.
If a con
fi
guration
fi
le was not created, you must recon
fi
gure the network settings, and rebuild the virtual
library and virtual drive con
fi
gurations, and the VLS300 storage pool con
fi
gurations (see
the section
called “Recreating the VLS300 storage pools”
. The cartridge con
fi
gurations, however, do not have to be
rebuilt, as they are stored on the disk arrays. See
Rebuilding the virtual library con
fi
guration
.
Restoring the virtual library con
fi
guration from a con
fi
guration
fi
le
Restoring the virtual library con
fi
guration from the con
fi
guration
fi
le restores the virtual library and virtual
drive con
fi
gurations, 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 con
fi
guration
fi
le:
1.
Set the network settings so you can open a Command View VLS session. See
Setting the network
settings
.
2.
Open a Command View VLS session and log in as the administrator. See
Opening a Command
View VLS session from Command View TL
.
3.
Add all secondary nodes using the Add Node Wizard. For each secondary node:
