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 or it may or may not disrupt traffic.
Table 4-3 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 Nondisruptive 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.
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:
„
QuickTools 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.
CAUTION!
Changes to the fabric may disrupt the NDCLA process.
Table 4-3. Switch Resets
Type Description
Hot Reset Resets a switch without a Power On Self Test. This reset activates
the pending firmware, but does not disrupt switch traffic. If errors
are detected on a port during a hot reset, the port is reset automat-
ically.
