McDATA® 4Gb SAN Switch for HP p-Class BladeSystem user guide 83
Installing firmware
Installing firmware involves loading, unpacking, and activating the firmware image on the switch. McDATA
Web Server does this in one operation. To provide consistent performance throughout the fabric, ensure
the following:
• All McDATA 4Gb SAN Switches are running the same version of firmware. Verify that this version of
firmware is compatible with the firmware of other M-series and McDATA switch models in the fabric.
• All other M-series and McDATA switch models are running the same version of firmware.
You can load and activate firmware on an operating switch without disrupting data traffic or having to
re-initialize attached devices. If you attempt to perform a non-disruptive activation without satisfying the
following conditions, the switch will perform a disruptive activation:
•
The current firmware version is a version that supports upgrading to the new version
• No changes are being made to switches in the fabric including powering up, powering down,
disconnecting or connecting ISLs, and switch configuration changes
• No port in the fabric is in the diagnostic state
• No zoning changes are being made in the fabric
•
No changes are being made to attached devices including powering up, powering down,
disconnecting, connecting, and HBA configuration changes
Ports that are stable when the non-disruptive activation begins and then change states, will be reset. When
the non-disruptive activation is complete, the switch automatically performs a hot reset. McDATA Web
Server or Element Manager sessions reconnect automatically. However, Telnet sessions must be restarted
manually.
When you need to do NDCLA/hot reset to multiple switches, only perform the NDCLA/hot reset on one
switch at a time, and allow a 75 second wait before performing the NDCLA/hot reset 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:
1. Select Switch > Load Firmware.
2.
Click
Browse, and browse for and select the firmware file to be loaded in the Load Firmware dialog.
3. 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.
4. Click OK to continue firmware installation, or click Cancel to cancel the firmware installation. The switch
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 and Element Manager 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
