Task 16: Plan Zone Sets for Multiple Products (Optional)

If name server zoning is to be implemented, carefully plan the characteristics and
security objectives (differentiation of operating systems, data sets, user groups,
devices, or processes) of zone members, zones, and zone sets.
If a fabric topology is implemented, zoning is configured on a fabric-wide basis.
Planning for zoned configurations must be carefully coordinated with planning a
fabric topology.
Consider the following factors when planning to implement name server zoning:

Planning and implementing zones and zone sets is a complex and difficult task,
especially for multi-switch fabrics. HP recommends you obtain planning
assistance from our professional services organization before implementing a
director or switch zoning feature.

Zone and zone set naming conventions — Directors and switches conform
to the open fabric naming convention by using the following zone and zone
set naming rules:
— Zone and zone set names can be up to 64 characters in length.
— The first character of the name must be an upper case alpha character
(A through Z) or lower case alpha character (a through z).
— Characters other than the first character can be upper or lower case
alphanumeric characters (A through Z, a through z, or 0 through 9), a
dollar sign ( $ ), hyphen ( - ), caret ( ^ ), or underscore ( _ ).
Zone members specified by port number or WWN — Consider if zoning is
to be implemented by port number or WWN. Because changes to port
connections or fiber-optic cable configurations may disrupt zone operation,
zoning by WWN is recommended.
Zoning implications for a multi-switch fabric — To ensure zoning is
consistent across a multi-switch fabric, directors and switches must have
compatible operating parameters and unique domain IDs, the active zone set
name must be consistent, and zones with the same name must have identical
elements.
Server and storage device access control — In addition to zoning, consider
implementing server-level access control (persistent binding) and
storage-level access control.
