If you are looking for a comprehensive list of commands for the service console or even understanding of the switches associated, you have probably used Mike Lavericks guides, searched the VMware documentation set and googled away. Well someone has submitted a link that has most if not all the commands that you will ever need to use and detail on them.

Its called the B2V Guide to VMware ESX Server 3 and can be found @ http://b2v.eu/b2vguide2vmware3.htm

They have the guide for ESX 2.x as well located @ http://b2v.eu/b2vguide2vmware.htm

an example of the content is shown below.

esxcfg-
 
There are a new set of command line tools in ESX 3.x which all start with "esxcfg-". These tools are used to configure each part of the ESX 3.x configuration. For example, esxcfg-firewall is used to manage the service console firewall while the esxcfg-nic is used to manage the physical Ethernet adapters present in the server.
Watch out for vicfg- commands also. If you are using the RCLI tools for managing ESX 3i, then the esxcfg- tools are now prefixed with vicfg- although the esxcfg- prefix still works.

 
esxcfg-advcfg

The esxcfg-advcfg command is interesting as there is not a huge amount of help about this command. However, we can figure out that it is meant to do advanced configuration and we can figure out some settings that can be made. The -g switch is used to "get" settings; the -s switch is used to "set" settings.
Here are a few examples of some VMkernel parameters which can be interrogated.

[root@esx1host vmware]# esxcfg-advcfg -g /Misc/BlueScreenTimeout
Value of BlueScreenTimeout is 0

[root@esx1host vmware]# esxcfg-advcfg -g /Misc/HostName
Value of HostName is esx1.vmlab.net 

[root@esx1host vmware]# esxcfg-advcfg -g /VMFS3/ZeroedThickVirtualDisks
Value of ZeroedThickVirtualDisks is 1

[root@esx1host vmware]# esxcfg-advcfg –g /Disk/SupportSparseLUN
Value of SupportSparseLUN is 1

[root@esx1host vmware]# esxcfg-advcfg –g /Disk/MaxLUN
Value of MaxLUN is

[root@esx1host vmware]# esxcfg-advcfg –g /Scsi/ConflictRetries
Value of ConflictRetries is

[root@esx1host vmware]# esxcfg-advcfg –g /LVM/EnableResignature
Value of EnableResignature is

The question is, how much is configurable? To figure out what is configurable, we recommend that you look in the directory /proc/vmware/config which you will find in the service console command line and then you will see the following directories

BufferCache
Cpu
Disk
FileSystem
Irq
LVM
Mem
Migrate
Misc
Net
NFS
Numa
Scsi
User
VMFS3

From these directories and the files within, you can work out the paths to be supplied to the esxcfg-advcfg command as parameters. Alternatively, you could also use the command

esxcfg-info –o

to list the advanced options.

When using the esxcfg-advcfg command, remember case sensitivity!
