Backup and Restore Features
The HAFM appliance provides two backup and restore features. One feature
backs up (to the HAFM appliance) 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:
■ NVRAM configuration — The NVRAM configuration for any managed
director or switch is backed up or restored through the Element Manager
application. Configuration data (stored in NVRAM on each director or
switch) backed up to the HAFM appliance 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.
■ HafmData directory — Critical information (for all managed products)
stored in the HafmData directory is backed up or restored using a backup
application. The application is configured to automatically back up the
contents of the data directory to a removable disk when the HAFM appliance
is rebooted or when directory contents change.
The HafmData directory includes:
— All HAFM configuration data (product definitions, user names,
passwords, user rights, nicknames, session options, SNMP trap recipients,
e-mail recipients, and Ethernet event notifications).
— All log files (HAFM logs and individual Element Manager logs).
— Zoning library (all zone sets and zone definitions).
— Firmware library.
— Call-home settings (phone numbers and dialing options).
— Configuration data for each managed product (stored on the HAFM
appliance and in NVRAM on each director or switch).
