Control path and data path failover

With today's high dependency on access to business information, safe guarded data and limited
backup windows, the reliability of the backup hardware and software is vital. Additionally backup
operations are usually automated, often run at night, and any first pass operator intervention is
done remotely. To assist with these enterprise demands, Hewlett Packard Enterprise supports
data path and control path failover for MSL2024, MSL4048, MSL8048, and MSL8096 tape libraries
with LTO-5 and LTO-6 FC tape drives. Failover functionality in the LTO-5 and LTO-6 tape drives
and in the tape libraries transfers the active path and all settings to the standby path following
failures.
Data path failover—a standby path is configured for the data path to the tape drive and
activated following link failures.
Library control path failover—a second drive is configured to host a standby library control
path that can be activated following link failures.
For additional information about path failover technology and configuration, see the HPE StoreEver
Tape Libraries LTO-5 and LTO-6 Failover User Guide, which is available from the HPE Enterprise
Information Library at http://www.hpe.com/info/storage/docs.
NOTE: Path failover is not currently supported for LTO-7 tape drives in the MSL2024, MSL4048,
MSL8048, or MSL8096 tape libraries.
