Control path and data path failover
With 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 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 and later generation tape drives in the MSL2024, MSL4048,
MSL8048, or MSL8096 tape libraries.
