Configuring Host Access to Storage Networking Drives
and Partitions
Note: Host access is available on all drives while host access controls
are only available on HP LTO-6 and LTO-7 drives.
The SNW Host Access feature provides a way to limit host access to
specific SNW tape drives and partitions via the library interface.
Note: This section describes host access for storage networking drives
and partitions only. For information about FC I/O blade LUN
mapping, see FC Host on page 204.
This section covers:
• Viewing All Access Groups on page 417 on page 383
• Requirements for Host Access on page 384
• Configuring Hosts on page 384
• Creating, Modifying, and Deleting Host Access Groups on
page 396
• Viewing All Access Groups on page 417
Without host access restrictions, all hosts can view all drives connected
to the SAN and all partitions to which there is a library control path.
Host access gives you the ability to deny/restrict access to specific hosts.
Details about host access include:
• If a control path drive has an SNW license applied to it, it will not be
seen by external applications until you create an access group and
add the host and partition to the access group.
• Access is granted using “access groups.” An access group is made
up of partitions, drives, and hosts. Drives and partitions can be in
multiple access groups, but each host can only be in one access
group.
• A partition can be assigned to a host access group if its control path
is through an SNW-licensed tape drive.
