Backup and Restore Features

The HAFM server provides two backup and restore features. One feature backs up
(to the HAFM server) or restores the configuration file stored in nonvolatile
random-access memory (NVRAM) on a director or switch CTP card. The other
feature backs up to a backup drive or restores the entire HAFM data (HafmData)
directory. The backup and restore features operate as follows:

SAN High Availability Planning Guide
Network Services — This function provides TCP/IP transport layers to
access management service subsystems from attached management clients.
These clients include the HAFM server or an SNMP management station.
Application Services — This function supports all software subsystems for
system initialization, logging, tracing, debugging, and communicating with
the RS-232 maintenance port.
Operating System Services — This function includes boot and loader
software, a command line monitor for engineering fault isolation, a serial
maintenance port driver, and other support for the product operating system.
Hardware Services (Edge Switch 2/16 and Edge Switch 2/32 Only) —
This function supports the application-specific integrated circuit (ASIC)
embedded on the CTP card, provides frame handling for edge switch ports,
and provides the application programming interface for light-emitting diodes
(LEDs), cooling fans, and power supplies.
NVRAM configuration — The NVRAM configuration for any managed
director or switch is backed up or restored through the Product Manager
application. Configuration data (stored in NVRAM on each director or
switch) backed up to the HAFM server includes:
— Identification data, such as the director or switch name, description, and
location.
— Port configuration data, such as port names, blocked states, extended
distance settings, and link incident (LIN) alerts.
— Operating parameters, such as buffer-to-buffer credit (BB_credit), error
detect timeout value (E_D_TOV), resource allocation timeout value
(R_A_TOV), switch priority, and preferred domain ID.
— Active zoning configuration.
— SNMP configuration parameters, such as trap recipients, community
names, and write authorizations.
