if your “remotehost” solaris  server cannot mount your “nfsserver” ‘s mountpoints, you can tunnel nfs over ssh

from the nfsserver

# ssh -R "3049:localhost:2049" remotehost

once in the “remotehost”

# mount -o port=3049 nfs://localhost:/nfs/share /mount/point

 

to get an address

ifconfig nxge0 plumb
ifconfig nxge0 dhcp start
ifconfig nxge0 dhcp status

remember to fsck after umounting the metadevice

this is over nxge4 and nxge10, vlan503 and vlan800, IMPORTANT: reboot after placing files

WARNING: USE CAREFULLY : WARNING

To label the disks you can use this script, just make sure you feed it the right disks, in this case it’s all that appear as “c6t” in my server

format < /dev/null | grep -i c6t | grep "<" | awk '{ print $2 }'| while read d;do printf "label\nyes\nquit\n" | format -d $d; done

This one will login to a list of servers and create a flar in a NFS share

#!/bin/ksh

for h in `cat hosts.txt`;do
        echo "----------------------- $h"
cat <<EOF  > /tmp/$h
mkdir -p /b; mount -F nfs 10.80.120.219:/space /b; ls /b
time flarcreate -n "$h" -c -S -R / /b/flars/$h.flar
umount /b
EOF
scp /tmp/$h $h:/tmp
ssh $h /tmp/$h
done

This one will run rsyncs in the background for each host it finds in hosts.txt, and save each host’s progress in a log.

#!/bin/ksh
for h in `cat hosts.txt`;do
 echo "----------------------- $h"
 (
 ssh $h df -k | egrep -v 'cdrom|^Filesystem|/$|/devices$|/system/contract$|/proc$|/etc/mnttab$|/etc/svc/volatile$|/system/object$|/etc/dfs/sharetab$|/dev/fd$|/tmp$|/var$|/var/run$|/dev/vx/dmp$|/dev/vx/rdmp$|/cores$|/var/crash$' | awk '{ print $NF }' | while read l;do
 mkdir -p /space/$h$l
 echo "rsync --progress -zrtva $h:$l/ /space/$h$l/"
 rsync --progress -zrtva $h:$l/ /space/$h$l/
 done
 ) 2>&1 > ${h}.log &
 done
