4 – Managing Switches Installing Firmware

Installing Firmware

Installing firmware involves loading, unpacking, and activating the firmware image on the switch. SANsurfer Switch Manager does this in one operation. To provide consistent performance throughout the fabric, ensure that all switches are running the same version of firmware.

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 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.
