62 Sun Storage Fibre Channel Switch 5802 QuickTools User Guide • September 2008
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.
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:
■ 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.
Note – If performing a Reset or a Hard Reset, the support files, the firmware image
files that have not been unpacked, and the configuration backup files that were
created on the switch will be deleted.
To reset a switch using QuickTools, do the following:
