femDump
Collects limited debug information to a remote directory through FTP, SFTP, or SCP. This command is a
minimal version of supportsave command.
SYNOPSIS femdump [-u user_name -p password -h host_ip -d remote_dir -l protocol]
DESCRIPTION Use this command to collect limited debug information to a remote directory through FTP or SCP. This
command is a minimal version of a supportsave command.
The files generated by this command are compressed before being sent off the switch. The core files and
panic dumps remain on the switch after the command is run. The FFDC data are removed after the
command has finished.
If there are blade processor (BP) blades installed on the switch, a support file (a tar.gz file) is generated
from each slot.
This command accepts IPv4 and IPv6 addresses. If the configured IP address is in IPv6 format, the RAS
auto-file transfer and event notification to syslog will not work in the case where the Fabric OS version is
downgraded. You must reconfigure auto-file transfer and syslog with IPv4 IP addresses.
In a Virtual Fabric environment, the command saves all chassis-based information and iterates through
the defined switch-based information for all logical switches. Chassis permissions are required to
execute this command.
Note that quotes should be used around path entries to ensure proper handling of special shell
characters.
NOTES The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
If you use anonymous FTP to run femDump on a chassis with multiple AP blades, configure the FTP
Windows server to allow unlimited anonymous users.
OPERANDS This command has the following operands:
-u user_name
Specifies the user name for the FTP, SCP, or SFTP server. This operand is
optional; if omitted, anonymous FTP is used.
-p password
Specifies the password for the FTP, SCP, or SFTP server. This operand is optional
with FTP; if omitted, anonymous FTP is used.
-h host_ip
Specifies the IPv4 or IPv6 address for the remote server.
-d remote_dir
Specifies the remote directory to which the file is to be transferred.
-l protocol
Specifies the transfer protocol. Valid values are File Transfer Protocol (FTP),
Secure Copy (SCP), or Secure File Transfer Protocol (SFTP).
If you plan to use SCP to transfer files, it is important to test the command prior to
its use with various SCP-mode services. Because the femDump command
makes several access requests to copy files, it is important that the SCP-mode
service be configured so that passwords are not required for each attempted
transfer. Failure to configure the service correctly may result in significant delays
in obtaining transferred output from the femDump command.
