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.
Table 9 describes the types of switch resets.
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 or
McDATA Element Manager 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 or McDATA Element Manager 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
To reset a switch, perform the following procedure:
1. Select the switch to be reset and open the faceplate display.
2. Select Switch > Reset Switch:
• Select Hot Reset to perform a hot reset
• Select Reset to perform a standard reset
• Select
Hard Reset to perform a hard reset
