7.

Click the Add Key button to upgrade the switch. Allow a minute or two for 
the upgrade to complete.

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.

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.

Changes to the fabric may disrupt the NDCLA process.
