Resetting a switch
Resetting a switch reboots the switch using the switch configuration parameters last saved in permanent
memory on the switch. 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.
During a hotreset 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.
NOTE:
Changes to the fabric may disrupt the NDCLA process. More than one McDATA Web Server
session will 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:
•
The McDATA Web Server session 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
