Installing Firmware

 

 

 

 

During a hotreset operation, fabric services will be unavailable for a short period (30-75 seconds depending on switch model). To ensure that an 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.

„Adding, moving or removing ISLs or other connections.

Management Interfaces:

After an NDCLA operation is complete, management connections must be re-initiated:

„SANsurfer Switch 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. To install firmware, do the following:

1.In the faceplate display, open the Switch menu and select Load Firmware.

2.In the Firmware Upload dialog, click the Browse button to browse and select the firmware file to be uploaded.

3.Click the Start button to begin the firmware load process. You will be shown a message warning you that the switch will be reset in order to activate the firmware.

4.SANsurfer Switch Manager prompts you to activate the new firmware using a hot (non-disruptive) reset, if possible. Click the OK button to reset the switch and activate the new firmware.
