Chapter 10: Path Failover
Configuring Host Access to Storage Networking Drives and Partitions

Quantum Scalar i6000 User’s Guide
• Drives must be licensed for SNW before they can be added to access
groups. Once a drive has been licensed for SNW, it is inaccessible to
hosts until they are granted access via the host access feature. See
License Drives for Path Failover
• Tape drives that are licensed for SNW can only be accessed by hosts
that are in the same host access group as the drives.
• Tape drives that are not licensed for SNW can be accessed by any
hosts that are zoned to the drives WWPN.
• If the control path and any control path failover tape drives for a
partition are licensed for SNW, then only the hosts in the same
access group as that partition will be able to send medium changer
commands to that partition. Hosts not in the same access group as
a partition will not be able to send medium changer commands to
that partition. However, hosts that are not in the same access group
as a partition do still have access and can send commands to any
non-SNW-enabled tape drives in that partition.
• Host access to a partition means the host can issue media changer
commands to the partition.
• Host access to a drive means the host can issue SCSI commands to
the drive.
Requirements for Host
Access
To use host access, you need the following:
• A Storage Networking license on the library (see
• Drives licensed for Storage Networking (see
• To add a partition to a host access group, the partition must have its
control path via a SNW drive (see
Configuring an IBM or HP LTO-5 or
later Drive as the Control Path
• Hosts configured (see
• Host access groups configured (see
Configuring Hosts
All hosts that are zoned or directly connected to the drives are available
to be assigned to host access groups. You may wish to modify existing
