Managing Switch Stacks; Configuring Switches In A Stack - HP StorageWorks 8/20q User Manual

• NTP (Network Time Protocol)—Enables the switch to obtain its time and date settings from an NTP
server. Configuring NTP on all of your switches and your workstations synchronizes the date/time
settings across the fabric and prevents difficulties with SSL certificates and event logs.
• CIM (Common Information Model)—Enables management of the switch through third-party
applications that use CIM.
• FTP (File Transfer Protocol)—Enables file transfers to the switch using FTP. FTP is required for out-of-band
firmware uploads, which complete faster than in-band firmware uploads.
• Management Server—Enables management of the switch through third-party applications that use the
GS-3 Management Server.
• Call Home—Enables you to configure switches and send alerts and events to email addresses or
pagers. This email-based Call Home cannot be used to contact HP Services. Call Home to HP Services
can be accomplished using HP Service Essentials Remote Support Pack as described in the HP
StorageWorks 8/20q Fibre Channel Switch Installation and Reference Guide or HP StorageWorks
SN6000 Fibre Channel Switch Installation and Reference Guide.

Managing switch stacks

The Enterprise Fabric Management Suite application recognizes switches as a stack if they are connected
by their high-speed XPAK stacking ports. Enterprise Fabric Management Suite auto-detects switches
connected by their XPAK ports and displays these stacked switches as a single stack entity in the faceplate
display (Figure
The graphic window (upper right pane of the faceplate display) displays one faceplate image for each
switch in the stack.
In the fabric tree (left window pane), the switches in each stack are nested under the stack icon, which is
nested under the fabric icon. Expanding the fabric and stack icons in the fabric tree displays all switches in
a stack. The lock image on the fabric icon indicates that the application is communicating with the fabric
through a secure (Secure Sockets Layer) connection.

Configuring switches in a stack

The stack dialog boxes are essentially the same as their corresponding switch dialog boxes, except that the
Select Switch for Initial Configuration drop-down list is added to each dialog box. The stack dialog boxes
display the information for the switch selected in the Select Switch for Initial Configuration drop-down list.
Click OK to apply the configuration for the selected switch to all other switches in the stack. The following
operations are available to configure the stack as a single entity:
• Syslog configuration. For more information, see "Syslog" (page 94).
• SNMP configuration. For more information, see
• Date/time and NTP settings. For more information, see
client" (page 91).
• Editing user accounts. For more information, see
• Security Consistency Checklist. For more information, see
• Firmware load and activation. For more information, see
• Zoning configuration. For more information, see
Additional stack operations include the following:
• Move the selected switch up or down one position in the stack within the graphic window. To move a
switch image up, select a switch, open the Stack menu, and select Move Switch Up. To move a switch
image down, select a switch, open the Stack menu, and select Move Switch Down. The Move Switch Up
menu is unavailable when you select the top switch in the stack. Similarly, the Move Switch Down is
unavailable when you select the bottom switch.
• Remove a switch from being associated with the stack if the switch is not connected to any other switch
in the fabric with an ISL connection. To remove a switch from a stack, select a switch, open the Stack
menu, and select Remove Switch.
• Remove a dead ISL connection in the stack display between two switches that is either offline or has
been physically disconnected. To remove a dead link (red), select one of the linked XPAK ports, open
the Stack menu, and select Remove Links.
