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 -4 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). To ensure that an NDCLA operation
is successful, verify that all administrative changes to the fabric (if any) are
complete. 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.
Management Interfaces:
After an NDCLA operation is complete, management connections must be
re-initiated:
SANbox 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.
CAUTION!
Changes to the fabric may disrupt the NDCLA process.
Table 4-5. 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
automatically.
