Saving Linux Dumps to Removable Media
Use the Linux commands below to save a dump to removable media. Each site is different, so the exact commands, file names, and device names will vary.
To save the dump from one node to another that has a tape drive, do the following:
1 After the node where the dump occurred has been recovered and is up and running, save the dump to a disk file. For example:
csp -mode save -target stream
Note: For a full description of the csp command, see the man page or pdehelp for csp.
2 After the file is written to disk, FTP the dumpfile to the node with the tape drive.
3 After you have FTPed the dumpfile to the node with the tape drive, copy the file to tape:
dd if=<dumpfile> of=<devicename> bs=<block_size>
Note: For a description of the dd command, see the Linux man page for the command.
4 If necessary, perform step 3 again until all of the dump files are on the tape. Then remember to use the “no rewind on open” and “no rewind on close” tape device options, that is /dev/rmt/c100t6d0s0nn.
Use standard operating system commands to burn the dump file to removable optical media, such as DVD.
