Click Next to start loading the configuration file.

After the configuration file is loaded, the system automatically applies the configuration and
reboots.

Manually Rebuilding the Virtual Library Configuration

If you are unable to manually restore the system from the configuration file, you must manually
reconfigure the network settings and rebuild the virtual library configuration:
1.

Set the network settings so you can open a Command View VLS session. See

Setting the

Network Settings

.

2.

Rebuild the virtual library and virtual drive configurations and re-enter your other configuration
settings, such as the notification alert settings. See

Configuration

,

Management

, and

Monitoring

.

NOTE:

If the node system board was ever changed and the virtual library configuration and

network settings were not saved to a configuration file, the persistent VLS serial number and Fibre
Channel port WWPNs are lost and cannot be recovered. The VLS firmware will automatically
generate a new VLS serial number and new Fibre Channel port WWPNs based on the node system
board's MAC address.

If this occurs, any capacity licenses installed on the VLS will no longer work, as they only work
with the VLS serial number for which they were issued. You can obtain new capacity licenses from
HP technical support using the new VLS serial number. You will also need to reconfigure your SAN
to reflect the new Fibre Channel port WWPNs.

Recovering from a VLS Disk Array RAID Volume Failure

If three or more hard drives have failed in a single VLS9200 disk array enclosure, a disk array
RAID volume failure has occurred. Each disk array enclosure is configured as one RAID6 volume.
A disk array enclosure RAID volume failure will corrupt all the data stored on the VLS storage pool
using that RAID volume, making it unrecoverable.

NOTE:

Only perform this procedure if a RAID volume failure has actually occurred. Other factors

can result in a false RAID volume failure being reported, such as a disk array enclosure being
powered down or the disk array enclosure external cabling being disconnected at either end.

To recover from a disk array enclosure RAID volume failure:
1.

Repair the failed RAID volume (for example, replace the failed hard drives in the RAID volume).
See

Hard Drive

.

2.

Erase all the virtual media from the disk array enclosures and rebuild all the RAID volumes on
the storage pool affected:
a.

Select Storage Pools in the navigation tree, then select the storage pool that needs recovery.

b.

Click Rebuild Storage Pool in the task bar.

c.

Click Rebuild.

d.

Click Yes to confirm.

3.

Recreate the cartridges that existed on the VLS storage pool.

VLS cartridge configurations are stored on the disk arrays and have been erased.

Recovering from a Node RAID Volume Failure

To recover from a node RAID volume failure, which occurs when both node hard drives fail:
1.

When restoring a primary node, power down all of the secondary nodes.

2.

Replace the failed node hard drives.
