Managing switches
During a hotreset operation, fabric services will be unavailable for a short period (30-75 seconds). To
ensure that an a Non-Disruptive Code Load and Activation (NDCLA) operation is successful, verify that all
administrative changes to the fabric (if any) are complete. When you need to do NDCLA/hotreset to
multiple switches, only perform the NDCLA/hotreset on one switch at a time, and allow a 75 second wait
before performing the NDCLA/hotreset operation on the next switch.
CAUTION:
Changes to the fabric may disrupt the NDCLA process. Common administrative operations
that change the fabric include zoning modifications, adding, moving or removing devices attached to the
switch fabric (this includes powering up or powering down attached devices), and adding, moving or
removing ISLs or other connections.
To install firmware using McDATA Web Server, perform the following procedure:
1.
Double-click a switch in the topology display to open the faceplate display.
2.
Select Switch > Load Firmware.
3.
Click Browse, and browse for and select the firmware file to be loaded in the Load Firmware dialog.
4.
Click Start to begin the firmware load process. You will be shown a message warning you that the
switch will be reset to activate the firmware.
5.
Click OK to continue firmware installation, or click Cancel to cancel the firmware installation. McDATA
Web Server will attempt a hot reset, if possible, to activate the firmware without disrupting data traffic.
During a non-disruptive activation, all Logged-In LEDs are extinguished for several seconds. If a
non-disruptive activation is not possible, an error message will be shown. To activate the firmware
image, the user may either resolve the error described in the message and perform a hot reset on the
switch or simply reset the switch (disruptive).
After an NDCLA operation is complete, management connections must be re-initiated:
•
McDATA Web Server sessions will re-connect automatically
•
Telnet sessions must be restarted manually
Applicable code versions:
•
Future switch code releases will be upgraded non-disruptively unless specifically indicated in its
associated release notes
•
An NDCLA operation to previous switch code releases is not supported
Using the CLI to install firmware
To install firmware using the CLI when a File Transfer Protocol (FTP) server is present on the management
workstation, use the Firmware Install command. Refer to the ”
more information. This command is disruptive to the fabric traffic.
1.
Enter the following command to download the firmware from a remote host to the switch, install the
firmware, then reset the switch to activate the firmware. If possible, a non-disruptive activation will be
performed.
McDATA4GbSAN (admin) #> firmware install
Warning: Installing new firmware requires a switch reset. Continuing
with this action will terminate all management sessions, including any
Telnet sessions. When the firmware activation is complete, you may log
in to the switch again.
