HP StorageWorks Fabric OS 5.X Advanced Web Tools Administrator Guide (AA-RVHYB-TE, September 2005)

Fabric OS 5.x Advanced Web Tools administrator guide 33
Opening modules in a secure fabric
When opening more than one module in a secure fabric, wait for each module to load completely before
opening another. For example, if you want to access both the Zone Admin and the Switch Admin
modules, open one of the modules and wait for it to load completely before opening the second module.
Abnormal behavior might occur if you attempt to open two modules simultaneously in a fabric with secure
mode enabled.
Certain Advanced Web Tools features are limited or disabled when secure mode is enabled on a fabric.
For more information about secure mode, see the HP StorageWorks Secure Fabric OS administrator
guide.
Primary-FCS-only functionality
The following Advanced Web Tools functionality is reserved for the primary FCS when secure mode is
enabled:
• Zoning administration is allowed only from the primary FCS switch when secure mode is enabled. For
all other switches in a secure fabric, the Zoning button is disabled.
• SNMP community strings can be modified only from the primary FCS switch when secure mode is
enabled. For non-FCS switches, you can view the SNMP community strings, but they are read-only,
and the SNMP access control lists on the SNMP tab are not displayed.
• User account administration is allowed only from the primary FCS switch when secure mode is
enabled. The changes are then propagated to all switches in the fabric.
Disabled functionality
Telnet access to a switch and the Telnet button in Advanced Web Tools are both disabled when secure
mode is enabled for a fabric. You must use sectelnet or SSH to access the Fabric OS CLI in a secure
fabric. These capabilities are not accessible from Advanced Web Tools. For more information on
sectelnet or SSH, see the HP StorageWorks Secure Fabric OS administrator guide.
The SNMP Access Control List is replaced with RSNMP_POLICY and WSNMP_POLICY when secure
mode is enabled for a fabric. The SNMP Access Control List is not displayed in Advanced Web Tools.
Recommendations for working with Advanced Web Tools
Listed below are recommendations when working with Advanced Web Tools:
• When using a mixed fabric—that is a fabric containing switches and directors running 4.x, 3.x, and
2.x firmware—use the most advanced switches or directors to control the fabric. For example, use the
5.x and 4.x switches or directors as the primary FCS, the location to perform zoning tasks, and the
time server (CLI). You should use the most recently released firmware on your switches.
• If switches are accessed simultaneously from different connections (for example, Advanced Web
Tools, CLI, and API), changes from one connection might not be updated to the other, and some
modifications might be lost. Make sure when connecting with simultaneous multiple connections that
you do not overwrite the work of another connection.
• Several tasks in Advanced Web Tools make fabric-level changes, for example, the tasks in the Zone
Admin module. When executing fabric-level configuration tasks, wait until you have received
confirmation that the changes are implemented before executing any subsequent tasks. For a large
fabric, this can be up to a few minutes.
• HP recommends a maximum of five simultaneous HTTP sessions to any one switch. An HTTP session is
considered a Fabric Manager or Advanced Web Tools connection to the switch.
