Usage Guidelines
The CallHome configuration commands available in the (config-callhome) submode.
A CallHome message is used to contact a support person or organization in case an urgent alarm is raised.
Once you have configured the contact information, you must enable the Call Home function. The enable command is required for the Call Home function to start operating. When you disable the Call Home function, all input events are ignored.
Note
Even if Call Home is disabled, basic information for each Call Home event is sent to syslog.
Examples
The following examples assign contact informations:
switch# snmp-server contact personname@companyname.com
switch(config-callhome)# email-contact username@company.com

Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(2).
Usage Guidelines
This command makes the running and the backup copy of the software identical.
A file can only be copied from an active supervisor to a standby supervisor, not from standby to active.
This command does not allow 127.x.x.x IP addresses.
The copy function will not be completed if the required space is not available in the directory. First change to the required directory (for example, cd bootflash:) and verify the available space (for example, dir bootflash:).
The entire copying process may take several minutes.
Do not copy a file from an external source directly to the standby supervisor. You must copy from the external source to the active supervisor, and then copy the saved file to the standby supervisor.
Examples
The following example saves your configuration to the startup configuration.
switch# copy system:running-config nvram:startup-config
The following example copies the file called samplefile from the slot0 directory to the mystorage directory.
switch# copy slot0:samplefile slot0:mystorage/samplefile
The following example copies a file from the current directory level.
switch# copy samplefile mystorage/samplefile
If the current directory is slot0:mydir, this command copies slot0:mydir/samplefile to
slot0:mydir/mystorage/samplefile.
The following command downloads a configuration file from an external CompactFlash to the running configuration.
switch copy slot0:dns-config.cfg system:running-config
The following command downloads a configuration file from an external CompactFlash to the startup configuration.
switch# copy slot0:dns-config.cfg nvram:startup-config
The following command saves a running configuration file to an external CompactFlash.
switch# copy system:running-config slot0:dns-config.cfg
The following command saves a startup configuration file to an external CompactFlash.
switch# copy system:startup-config slot0:dns-config.cfg
The following example creates a copy of the binary configuration in NVRAM.
switch# copy system:running-config nvram:startup-config
The following example creates a backup copy of the binary configuration.
switch# copy nvram:startup-config nvram:snapshot-config
The following example overwrites the contents of an existing configuration in NVRAM.
