In my lab environment I used iscsi as my shared storage. Today I have removed network adapters from software iscsi adapter to do some other networking stuff. After a while when im trying  to reconfigure iscsi im getting below error


Call ïscsimanager.query candidatenics"



To resolve this problem I had to reset iscsi from esx shell by following below steps


find iscsi config locations









navigate to the iscsi config location /etc/vmware/vmkiscsid




Delete all the files & reboot esx host

How to convert VMDK to RDM

Posted by dja234 Feb 16, 2017

1. Identify the disk which we want to convert


2. Identify the raw disk which we are going to point this VMDK.(in this example we are using iscsi target). We need to copy naa id


3. Convert vmdk using vmkfstools command. This will create new vmdk pointer to rdm file


4. Remove existing vmdk file and map new RDM to the vm


In a most of the vmware infrastructure environment we are using stndard vswitches . the limitation is the standard vsiwtch is when we are doing any modification and when we are creating vswitches, we have to do it manually an individually. If we have multiple port groups its a very difficult this. To avoid this thing, we can use vmware distirbuted switch. but we need to purchase enterprise plus license. To simplify this process i have created small power-shell script. I will explain this script by using my example.


i have two esxi host and esx-01. corp.local is already configured with required port groups. now we need to create all the port groups in esx-02. corp.local . therefore first i have created vswitch0 in esx-02. Then Using my scrript i can create all the port groups same as esx-01





Connect-ViServer vcsa-01a.corp.local  # Connect to Vcenter Server

$strvswitchonhost02=get-virtualswtich -name vswitch0 -vmhost esx-02a.corp.local  # Host 01 have virtual switch named vswitch0, we have to create same switch in host 02. Its already created and $strvSwitchonhost02 variable store that details

$strsovirprgrp= get-virtualporggropu -vmhost esx-01a.corp.local -virtualswitch vswitch0 -standard # Store all the virtual port details in a $strsovirprgrp array


For ($a=0 ; $a -le $intcount-1 ; $a++)




New-virtualporggroup -virtualSwitch $strvswitchonhost02 -name $strname -VLANId  $intvlan # create virtual port group/s on second host
