This topic describes how to copy the networking and SAN File System configuration files before upgrading the SAN File System.
You can copy the files to any location to which you will have access after upgrading the metadata server. For example, you can copy the configuration files to a diskette.
tar -cPvf network_config_mds2 /etc/HOSTNAME /etc/sysconfig/network/ifcfg-eth* /etc/sysconfig/network/routes /etc/hosts /etc/resolv.conf
tar -cPvf network_config_mds2 /root/.tank.passwd /etc/tank/server/Tank.Bootstrap /etc/tank/server/Tank.Config /etc/tank/admin/config/tank.properties ...remaining files ...
If you copy the files to another location in the network, you will need to ensure that you have network connectivity to restore them when needed.
mount /dev/fd0 /media/floppy
cp network_config_mds2 /media/floppy
cp sfs_config_mds2 /media/floppy
ls /media/floppy
unmount /media/floppy
