Disk Rebalance

Start Rebalance disks

vsan.proactive_rebalance --start --time-span 86400 --variance-threshold 0.30 --time-threshold 1800 --rate-threshold 100000 <cluster path>

Stop Rebalance disks

vsan.proactive_rebalance --stop <cluster path>

Check Rebalance status

vsan.proactive_rebalance_info /localhost/SouthEast/computers/Raleigh

vsan.resync_dashboard /localhost/SouthEast/computers/Raleigh

Cluster

Remove host or witness from fault domain

esxcli vsan cluster leave

Troubleshoot

esxcli vsan cluster get

vsan.check_state .

vsan.disks_info <host path>

Stress Test

/localhost/SouthCentral/computers/Houston> vsan.health.cluster_load_test_run -r houston_stress -t "Stress test" -d 28800 ./

Check vSAN upgrade status

vsan.upgrade_status -r 60 /localhost/VSAN-DC/computers/VSAN-Cluster/ 

Decrypt Files from QNAP with OpenSSL

If you have encryption enabled on your QNAP storage, to decrypt it, do the following.

Decrypt one file
     openssl enc -d -aes-256-cbc -k <decrypt password> -in filename.jpg -out filename.jpg


Decrypt multiple files in a folder.
     for f in * ; do [ -f $f ] && openssl enc -d -aes-256-cbc -k <decrypt password> -in $f -out _$f;

Change Network Failover Detection Policy on vSwitches and Portgroups

This script traverses all clusters and host and check if Beacon Probing is set the NetworkFailoverDetectionPolicy.  If Beacon Probing is set, change it to Link Status.

#import-module VMware.VimAutomation.Core

#Connect-VIServer -Server vcenter_hostname

#uncomment for testing

#$vmhosts = "hostname1","hostname2"

　

#uncomment for live run

#get the hostnames of all the hosts in every cluster

$vmhosts = get-cluster | get-vmhost | select name

foreach($vmhost in $vmhosts)

{

    #Gets all the vSwitch names that has beacon probing set on the host.

    $switch_policy = Get-VirtualSwitch -VMHost $vmhost.Name | where {$_.Name -ne "vSwitchiDRACvusb"} | Get-NicTeamingPolicy | Where-Object {$_.NetworkFailoverDetectionPolicy -eq "BeaconProbing"} | select -ExpandProperty VirtualSwitch # | select VirtualSwitch | format-wide
