3. Configure the new FTP server to use port 21.
4. Start the new FTP server.
Collecting FDMI device information
FDMI device information is updated once a day as a server-side service, with a few exceptions:
• Downloading firmware to HBAs starts FDMI data collection so that the data matches the download.
• FDMI data for a new fabric is collected when it is discovered. Because the device nodes and ports must
be in the database prior to storing FDMI data, data collection does not start until the device discovery
is complete.
You can, at any time, select Discovery > Refresh Fabric to update the FDMI device information.
If FDMI data cannot be collected, an alert appears with a brief description of the problem. The alert
remains unresolved until the server can collect FDMI for that fabric.
NOTE: There must be at least one FDMI-capable switch in the fabric for FDMI information to be
collected.
Rebooting switches
This section provides information on creating reboot groups and performing sequenced reboots. A reboot
group contains one or more switches from a single fabric. You cannot group switches from different fabrics,
and each switch can belong only to one reboot group.
Create a reboot group containing multiple switches from the same fabric if you want the selected switches
to reboot simultaneously. You might want to create reboot groups containing switches that run the same
firmware, serve the same function, reside in the same physical location, or share any other attribute. After
creating reboot groups, you can then configure a sequential reboot of the reboot groups.
A sequenced reboot allows different areas of your SAN to reboot and stabilize before other switches in the
fabric begin to reboot. This reduces the load of interswitch traffic on the SAN. For example, you can use
the following reboot strategies:
• Simultaneously reboot switches that run the same firmware.
• Simultaneously reboot switches of the same model.
• Reboot the core switches of a fabric and then the edge switches.
• Reboot the backbone of a large SAN and then reboot other sections.
• Reboot distant physical locations sequentially.
Consult the following sections for information about creating reboot groups containing single or multiple
switches, adding switches to existing reboot groups, and configuring a sequenced reboot:
• Creating a reboot group with multiple switches, next
• Creating single-switch reboot groups, page 162
• Assigning switches to a reboot group, page 163
• Performing a sequenced reboot, page 163
Creating a reboot group with multiple switches
Create a reboot group containing more than one switch if you want the switches to reboot simultaneously.
To create a reboot group:
1. Select Tools > Reboot > Create Reboot Sequence.
The Create or change reboot groups and sequence window opens (Figure 98).
