Resetting a switch

Resetting a switch reboots the switch using configuration parameters in memory. Depending on the reset type, a switch reset may or may not include a Power-on Self Test (POST), or it may or may not disrupt traffic. Table 9 describes the types of switch resets.

During a hot reset operation, fabric services will be unavailable for a short period (30-75 seconds depending on switch model). Verify all administrative changes to the fabric (if any) are complete before performing an Non-disruptive Code Load and Activation (NDCLA). When upgrading firmware across a fabric using non-disruptive activation, upgrade one switch at a time and allow 75 seconds between switches.

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

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

•McDATA Web Server or 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.
