Fastpass

Using fastpass to run commands:

  1. First set up fastpass by adding servers that can be used by fastpass (this only needs to be done once):

    vifp addserver vmware-01.example.org --username admin

  2. Set one of the servers you added as a fastpass target for running commands on:

    vifptarget -s vmware-01.example.org

  3. Run command: run any command as usual, and it will run on the targeted fastpass server

Add multiple servers to fastpass at once:

for n in $(seq -f "%02g" 1 32); do vifp addserver vmware-$n.example.org --username admin --password adminpass; done

Run commands on multiple servers at once (configure and restart syslog):

for n in $(seq -f "%02g" 1 32); do echo vmware-$n.example.org; vifptarget -s vmware-$n.example.org; esxcli system syslog config set --loghost='tcp://splunk.example.org:1514'; esxcli system syslog reload; esxcli network firewall ruleset set --ruleset-id=syslog --enabled=true; esxcli network firewall refresh; esxcli system syslog config get; done

List servers added to fastpass:

vifp listservers

List fastpass targets:

vifptarget -d

Clear fastpass targets:

vifptarget -c

Misc

Change the DNS servers on multiple ESXi hosts:

for n in $(seq -f "%02g" 1 32); do vifptarget -s vmware-$n.example.org; vicfg-dns -D 192.168.0.10,192.168.0.11; vicfg-dns; done

Change the management network subnet mask on multiple ESXi hosts:

for n in $(seq -f "%02g" 1 32); do echo vmware-$n.example.org; vifptarget -s vmware-$n.example.org; vicfg-vmknic --ip `vicfg-vmknic -l | grep vmk0 | awk '{print $5}'` -n 255.255.255.0 "Management Network"; done

Change the default gateway on multiple ESXi hosts:

for n in $(seq -f "%02g" 1 32); do echo vmware-$n.example.org; vifptarget -s vmware-$n.example.org; vicfg-route 192.168.0.1; vicfg-route -l | grep default; done

Remove a NIC from a dvSwitch on multiple ESXi hosts:

for n in $(seq -f "%02g" 1 32); do echo vmware-$n.example.org; vifptarget -s vmware-$n.example.org; esxcfg-vswitch -Q VMNIC -V ` esxcfg-vswitch -l | grep VMNIC | egrep -v DVSWITCH | cut -c 4-7` DVSWITCH; done

(replace DVSWITCH with the name of the dvSwitch and VMNIC with the vmnic to remove)
