Advanced POWER Virtualization on IBM System p5 - Previous ...

Note: You can use dsh based on rsh, ssh, or Kerberos authentication as long
as dsh can run commands without being prompted for a password.
See Example 5-20 for information about how to run fixdualvios.ksh in parallel on
partitions dbserver, appserver, and nim.
Example 5-20 Using a script to update partitions
# dsh -n dbserver,appserver,nim /tmp/fixdualvios.ksh | dshbak >\
/tmp/fixdualvio.out
Tip: Use the DSH_LIST= variable so you do not have to type
in the names of the target LPARs when using dsh.
Tip: Use the DSH_REMOTE_CMD=/usr/bin/ssh variable if you use ssh for
authentication.
Tip: The output file /tmp/fixdualvio.out will reside on the system running the
dsh command.
The dshbak command will group the output from each server.
Example 5-21 shows how to run the script and the output listing from the
partitions dbserver, appserver, and nim.
Example 5-21 Running the script and listing output
# export DSH_REMOTE_CMD=/usr/bin/ssh
# export DSH_LIST=/root/nodes
# dsh /tmp/fixdualvios.ksh|dshbak > /tmp/fixdualvios.out
