McDATA® 4Gb SAN Switch for HP p-Class BladeSystem Installation Guide (AA-RW1XC-TE, November 2006)

McDATA® 4Gb SAN Switch for HP p-Class BladeSystem installation guide 33
Using McDATA Web Server or Element Manager to install firmware
Installing firmware involves loading, unpacking, and activating the firmware image on the switch. McDATA
Web Server and Element Manager do this in one operation. To provide consistent performance throughout
the fabric, ensure that all McDATA 4Gb SAN Switch for HP p-Class BladeSystem switches are running the
same version of firmware. Verify that this version of firmware is compatible with the firmware of other
McDATA switch models in the fabric.
The pending firmware version will differ from the active version during the brief period while the switch is
resetting to activate the firmware. Firmware management tools enable you to install and activate new
firmware.
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.
Future switch code releases will be upgraded non-disruptively unless specifically indicated in the associated
release notes. An NDCLA operation to previous switch code releases is not supported.
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 or Element Manager:
1. Select Switch > Load Firmware.
2. Click Browse, and browse for and select the firmware file to be loaded in the Load Firmware dialog
box.
3. Click Start to begin the firmware load process. A message warns 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 attempts 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.
An error message notifies you if a non-disruptive activation is not possible. To activate the firmware
image, the user can either resolve the error described in the message and perform a hot reset on the
switch, or simply reset the switch.
5. After an NDCLA operation is complete, management connections must be re-initiated:
• McDATA Web Server and Element Manager sessions automatically reconnect.
• You must restart Telnet sessions.
