Backup And Restore Features - McDATA StorageWorks 2/140 - Director Switch Planning Manual

Backup and Restore Features

• Fabric services - This function supports the fabric controller
(login server) and name server. For redundant directors, fabric
services also implement a replication manager that synchronizes
node port (N_Port) registration databases between redundant
CTP cards and allows CTP failover.
• Loop services - This function supports FL_Port initialization for
Sphereon 4000-Series Switches and implements arbitrated loop
functions, such as transmission of loop initialization primitives
(LIPs).
• Port hardware services (fabric switches only) - This function
supports the application-specific integrated circuit (ASIC)
embedded on the CTP card, provides frame handling for fabric
switch ports, and provides the application programming
interface for light-emitting diodes (LEDs), cooling fans, and
power supplies.
Refer to Appendix B, Firmware Summary
about the differences and similarities between the operating systems.
The appendix includes three tables that summarize system-related,
Fibre Channel protocol-related, and management-related differences.
The management server provides two backup and restore features.
One feature backs up (to the management server or any LAN-
connected trivial file transfer protocol (TFTP) server) or restores the
configuration file stored in nonvolatile random-access memory
(NV-RAM) on a director CTP card, fabric switch, or SAN router. The
other feature backs up (to the CD-RW drive) or restores the entire
SAN management data directory. The backup and restore features
operate as follows:
• NV-RAM configuration (director or fabric switch) - The
NV-RAM configuration for any managed director or fabric switch
is backed up or restored through the associated Element Manager
application. Configuration data (stored in NV-RAM on each
director or switch) backed up to the management server includes:
— Identification data, such as the product name, description,
and location.
— Port configuration data, such as port names, port states,
extended distance settings, and link incident (LIN) alerts.
