Using the Alert Panel
This panel, located below the navigation control panel, displays a colored alert symbol
that indicates the most critical status of any product managed by the Fabric Manager. For
example, if one product has failed, and nine other products are fully operational, a red
diamond with yellow background, indicating a product failure, displays in the alert panel.
The alert panel displays one of four alert symbols as described in Table 21.
Using the Topology View
The Topology View displays all products in a fabric, as well as the interswitch links
between products in a multiswitch fabric. Switches and directors that are being managed
by another SDCM server display without an alert symbol.
Like the Fabric View, the icons in the Topology View have a pass-over functionality. When
the pointer is placed over an icon, the icon's label expands to display the complete WWN
or nickname of the director. This expanded label displays detailed information for
managed products. The type of information displayed is determined by the display options
selected.
The status table at the top of the Topology View displays the selected fabric's WWN,
operational status, and domain ID of the principal switch. The Fabric Status shows one of
the following:
s Operational
All units in the fabric are operational. If one managed product is degraded but
operational (indicated by a yellow triangle status symbol behind the product icon), the
fabric is operational.
s Unknown
No information about the fabric is available. This status typically results after removal
or failure of the fabric's principal switch.
s Transitioning
This state occurs during a fabric build just before the fabric becomes operational.
Unless a problem occurs, this status appears only briefly.

Determining the Default Zone Status
A default zone consists of all devices that have not been configured as members of a zone
in a currently enabled (active) zone set. You can enable or disable the default zone
separately from the active zone set.
The state of the default zone (enabled or disabled) displays at the top of the view.
s When no zone set is active and the default zone is enabled, then all devices are
considered to be in the default zone.
s If a zone set is active, then all connected devices that are not included in at least one of
the zones in the active zone set are included in the default zone.
s If no zone set is active and the default zone is disabled, then no device can access or
communicate with any other device in the fabric.
Deactivating a Zone Set
Click the Deactivate Zone Set button at the bottom of the Zoning View to display the
Deactivate Zone Set dialog box (Figure 311), where you can deactivate the currently

Fabric Zoning
This chapter explains how to:
s Zone fabrics
s Use zoning features and dialog boxes
Over view
NOTE: Designing zoning can be a complex task, especially for multiswitch fabrics. Refer to
Compaq's professional services organization before configuring zoning.
The fabric zoning feature enables you to partition devices attached to managed Fibre
Channel products into groups called zones. A zone contains devices that can access one
another through port-to-port connections. Devices in the same zone can recognize and
communicate with one another; devices in different zones cannot.
System administrators create zones to increase system security and to prevent data loss or
corruption by controlling access between devices (such as servers and data storage units),
or between separate user groups (such as engineering or human resources). Zoning allows
an administrator to:
s Establish barriers between devices that use different operating systems. For example, it
is often critical to separate servers and storage devices with different operating systems
because accidental transfer of information from one to another can delete or corrupt
data. Zoning prevents this accidental transfer of information by grouping devices that
use the same operating systems into zones.
s Create logical subsets of closed user groups. Administrators can authorize access
rights to specific zones for specific user groups, thereby protecting confidential data
from unauthorized access.
42 SANworks Director Connectivity Manager
s Create groups of devices that are separate from devices in the rest of a fabric. Zoning
allows certain processes (such as maintenance or testing) to be performed on devices
in one group without interrupting devices in other groups.
s Allow temporary access between devices for specific purposes. Administrators can
remove zoning restrictions temporarily (for example, to perform nightly data backup),
then restore zoning restrictions to return to normal processes.
Figure 41 illustrates three zones established on a single managed product with four
devices in each zone. Devices in each zone can communicate with and access devices only
in their respective zones.

Zoning Concepts
Zoning is configured by authorizing or restricting access to name server information
associated with device ports that attach to product ports. A zone member is specified by
the number of the product port to which a device is attached, or by the 8-byte world-wide
name assigned to the host bus adapter or Fibre Channel interface installed in a device. A
device port can belong to multiple zones.
44 SANworks Director Connectivity Manager
Zoning concepts include:
s Zones
s Default Zone
s Zone Sets
s Zone Library
s Active Zone Set
Zones
A zone is composed of a set of members (maximum 4096) that can access each other. A
member can be a product port or the WWN of the device. Ports and devices spread
throughout multiple managed products in a multiswitch fabric may be grouped into the
same zone. Members of a zone can communicate with one another; members in different
zones cannot. The number of members that you can configure for a zone varies according
to the number of zones in the zone set, the length of the zone names, and other factors, but
is essentially bounded by the available nonvolatile random-access memory (NVRAM) in
the managed product.
The type of zone members identified for a zone may be mixed and matched. For example,
two members may be specified by a port number and the third member by the WWN of
the device.
Please note the following naming conventions when naming zones:
s The first character of a zone name must be a letter (A-Z, a-z).
s A zone name cannot contain spaces.
s Valid characters are all letters, all numbers, and the special characters ($-^_).
s A zone name can have a maximum of 64 characters.
Using WWNs
To identify a zone member by WWN, use the 16-digit WWN of the device. For example:
10:00:08:00:88:40:C0:D4
In the SANworks DC Manager, Fabric Manager and Product Manager, the WWN is
preceded with the switch or director manufacturer's name. The WWN is assigned to the
Fibre Channel interface or HBA installed in devices such as servers or storage devices.
Although the device may also have a node WWN, this WWN is not used for zoning
Fabric Zoning 4 5
identification. If you have assigned a nickname to the WWN through the Configure
Nicknames dialog box, that nickname appears when you point to the WWN. In this case,
you will assign the nickname as the zone member.
The advantage of identifying a zone member as the WWN of the attached device is that
the identification will not change if fiber cable connections to ports are rearranged. This is
especially important if you are using spare ports. You can simply move the fiber cable to a
spare port from a failed port and still maintain the zoning configuration.
The disadvantage of identifying a zone member by the WWN is that removal and
replacement of a device HBA or Fibre Channel interface (thereby changing the device
WWN) disrupts zone operation and may incorrectly include or exclude a device from a
zone.
Using Port Numbers
To identify a zone member by port number, use the domain identification number of the
managed product and the port number on that managed product. For example:
Domain 1, Port 1
Port numbers can be 0-n, with n representing the number of ports on the managed product
minus one. When you define a zone member by a port number, any device attached
through that port is included in the zone. A port number that you assign as a zone member
is automatically prefixed with the domain identification number of the managed product.
The advantage of identifying a zone member by port number is that if the HBA on an
attached device fails, you do not have to identify the member with the WWN of the
replacement HBA.
A disadvantage of port zoning is that someone may rearrange cable connections to ports
(because of port failures or other reasons) and inadvertently allow devices to communicate
that should not have access to each other.
NOTE: If a managed product's Domain ID changes, you must reconfigure all zones that
contained the managed product's port as a zone member. Compaq recommends assigning
unique preferred Domain ID's to each switch in the fabric using the Operating Parameters dialog
box in the Product Manager.
46 SANworks Director Connectivity Manager
Default Zone
A default zone consists of all devices that have not been configured as members of a zone
in a currently active zone set. Here are some important points to remember about zone
sets:
s You can enable or disable the default zone separately from the active zone set using the
Default Zone option in the Configure menu. Enabling the default zone allows all
devices and ports not configured as members of the active zone set to communicate. If
the default zone is disabled, these ports and devices cannot communicate.
s When no zone set is activated, then all devices are considered to be in the default zone.
s If a zone set is active, then all connected devices that are not included as a members of
a zone in the active zone set are included in the default zone.
Zone Sets
A zone set is a group of zones that you can activate or deactivate as a single entity across
all managed products in either a single switch or a multiswitch fabric. Only one zone set
can be active at one time. Devices that are members of zones in the zone set can only
communicate with members of zones in the same zone set. However, devices can be
included as members of more than one zone set. By activating a zone set, you are making
all zones in the set active. You can configure up to 1024 zones in a zone set and up to 64
zone sets.
Here are some important points to remember about zone sets:
s If no zone set is active, and the default zone is disabled, then no devices can
communicate.
s If you activate a zone set when there is already an active zone set, that set will replace
the currently active zone set.
s If you deactivate the current active zone set, then all devices connected in the fabric
become members of the default zone.
Please note the following naming conventions when naming zone sets:
s The first character of a zone set name must be a letter (A-Z, a-z).
s A zone set name cannot contain spaces.
s Valid characters are all letters, all numbers, and the special characters ($-^_).
s A zone set name can have a maximum of 64 characters.
Fabric Zoning 4 7
Active Zone Set
An active zone set is a zone set that is currently active on a single-switch fabric or across
all managed products in a multiswitch fabric. At any time, you can disable zoning by
deactivating the active zone set and enabling the default zone, or you can enable zoning by
activating a zone set. When a zone set is active, all zones that are members of that zone set
are active. Only one zone set can be active for the fabric at one time. If no zones are active,
then all devices are considered to be in the default zone.
Zone Set Library
The Zone Set Library contains all of the zone sets configured through the Fabric Manager.
Any zone set in the library may be selected and activated on a fabric. You can view this
library through the Zone Sets dialog box. This dialog box provides a branching tree
structure of all zone sets, zones, and members of each zone.
Zone Library
The Zone Library contains all zones configured through the Fabric Manager. Any zone in
the library may be selected and added to a zone set. You can view this library through the
New Zone Set and Modify Zone Set dialog boxes. By selecting a zone and clicking View
Zone Members on the dialog box's Actions menu, you can see all members currently in a
zone.
Controlling Access at the Server or Storage Device
Features available at the server or storage device can add methods, beyond zoning, to
increase network security measures, differentiate between operating systems, and prevent
data loss or corruption by controlling access between devices or between separate user
groups (such as Engineering or Human Resources).
Server-level access control is called persistent binding. Persistent binding uses
configuration information stored on the server and is implemented through the server's
host bus adapter (HBA) driver. The process binds a server device name to a specific Fibre
Channel storage volume or logical unit number (LUN), through a specific HBA and
storage port WWN. In essence, this feature creates a reliable route across the fabric that
sustains the small computer system interface (SCSI) connection between a server and
storage device.
48 SANworks Director Connectivity Manager
For persistent binding:
s Each server HBA is explicitly bound to a storage volume or LUN, and access is
explicitly authorized (access is blocked by default).
s The process is compatible with open system interconnection (OSI) standards. The
following are transparently supported:
Different operating systems and applications.
Different storage volume managers and file systems.
Different fabric devices, including disk drives, tape drives, and tape libraries.
s If the server is rebooted, the server-to-storage connection is automatically
re-established.
s The connection is bound to a storage port WWN. If the fiber optic cable is
disconnected from the storage port, the server-to-storage connection is automatically
re-established when the port cable is reconnected. The connection is also automatically
re-established if the storage port is cabled through a different managed product port.
Access can also be controlled at the storage device as an addition or enhancement to
redundant array of independent disks (RAID) controller software. Data access is
controlled within the storage device, and server HBA access to each LUN is explicitly
limited (access is blocked by default). Storage-level access control:
s Provides control at the storage port and LUN level, and does not require configuration
at the server.
s Is typically proprietary and protects only a specific vendor's storage devices.
Storage-level access control may not be available for many legacy devices.
NOTE: Refer to Compaq's professional services organization before establishing persistent
binding.
NOTE: Refer to Compaq's professional services organization when establishing access control
features at the storage device.
Merging Zoned Fabrics
Managed products are linked through ISLs to form multiswitch fabrics. In a multiswitch
fabric, the active zoning configuration applies to the entire fabric. Any change to the
configuration applies to all switches in the fabric.
Fabric Zoning 4 9
Configurations of Merged Zoned Fabrics
When fabrics join through an ISL, adjacent managed products exchange active zone
configurations and determine if the configurations are compatible and can merge. If the
configurations can merge, the fabrics join. The resulting configuration will be a single
zone set containing zone definitions from each fabric.
If configurations cannot merge, the expansion ports (E_Ports) on each product become
segmented. Segmented E_Ports cannot carry traffic from attached devices (class 2 or 3
traffic), but can carry management and control traffic (class F traffic) between managed
products.
Zoning configurations are compatible if the active zone names in each fabric are unique. If
there are identical zone names in each fabric, then the zones must have identical members
for the fabrics to join.
Rules for Merging Zoned Fabrics
Certain rules are enforced to ensure that zoning is consistent across the fabric. Table 41
summarizes rules for joining two fabrics through an ISL. The the following terms are used
in the table:
s Not zoned
No zone set is active in the fabric and the default zone is enabled. In other words, all
devices in the fabric are visible to all other devices in the fabric.
s Zoned
A zone set is active in the fabric and/or the default zone is disabled. In this case,
devices can discover other devices that are members of the same zone.
s Zoning configuration
Combination of the active zone set definition and the default zone state (enabled or
disabled).
Table 41: Merging Fabrics - Results for Zone Configurations
Fabric A Fabric B Result
Not zoned Not zoned Fabrics join successfully. The new fabric remains not zoned.
Not zoned Zoned Fabrics join successfully and the active zone set will propagate
across the fabric. Fabric A inherits zoning configuration from
Fabric B.
410 SANworks Director Connectivity Manager
Table 41: Merging Fabrics - Results for Zone Configurations (Continued)
Fabric A Fabric B Result
Zoned Not zoned Fabrics join successfully and the active zone set will propagate
across the fabric. Fabric B inherits zoning configuration from
Fabric A.
Zoned Zoned Fabrics can merge if the zone names in each fabric are unique.
The resulting active zone set is a union of the zones from each
fabric. Once you have merged the two zoned fabrics, click the
Save Active Zone Set As button in the Zoning View to save the
active zone set to the zone set library.
If there is a zone name conflict (the same zone name in each
fabric) then the zones must have identical members for the
fabrics to join.
If the two zones have the same name but contain different
members, then the E_Ports will segment and the fabrics will not
join.
NOTE: If merging zones will result in segmented E_Ports and the fabrics will not join, you can
join the fabrics by deactivating the active zone set on one of the fabrics (default zone is
enabled). This eliminates any conflicts because the fabrics will then join using only the active
zone set. After the fabrics join, you can make adjustments to zoning configurations as you
desire.
Configuring and Managing Zoning
This section contains detailed steps for establishing new zones and zone sets in a fabric.
Steps are also provided for other zoning tasks. In addition, a quick reference chart on using
zoning options and dialog boxes to perform specific zoning tasks is included in Table 42.
NOTE: Designing zoning can be a complex task, especially for multiswitch fabrics. You should
obtain help from Compaq's professional services organization before configuring zoning.

Using zoning options available from the Configure menu, you can establish zones for
devices attached to ports in one product (single-switch fabric) or in multiple products
linked through ISLs. A fabric containing multiple managed products linked through ISLs
is called a multiswitch fabric.
Configuring New Zoning for a Fabric
Use the following tasks to configure a new zone and zone set, then activate the new zone
set for the fabric. Steps are provided in each task to show how to use dialog boxes and
other features of fabric zoning.
All features to configure zones and zone sets are available through the Zone Sets dialog
box. To display this dialog box, choose Zone Sets from the Configure menu.
Task 1: Create Zones
A zone is a set of physical ports on managed products in the fabric and/or devices attached
to the ports. Ports are identified by the managed product domain and physical port
member. Devices are identified by the WWN of the device. Use this task to define and add
up to 1024 zones.
To create zones, perform the following steps:
1. In either the Topology View or Zoning View, choose Zone Sets from the Configure
menu.
The Zone Sets dialog box displays.
The Zone Set Library area of the Zone Sets dialog box displays all of the defined zone
sets. If zone sets are not defined, this library is empty. Click the horizontal magnifying
glass icon by a zone set to expand the list of zones included in the set. Click the
vertical magnifying glass icon by a zone to expand the list of members included in the
zone (as shown in Figure 44).
