Utilities reference
These command-line utilities are only accessible through VMware TSM, also known as SSH, on ESXi and the
COS on ESX.
IMPORTANT:
VMware suggests that TSM only be used for the purposes of troubleshooting and
remediation. VMware recommends using the vSphere Client or any other VMware Administration
Automation Product to perform routine ESXi host configuration tasks that do not involve a
troubleshooting scenario. For more information on using TSM, see the VMware Knowledge Base
article
(http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&
externalId=1003677).
The VSL installation packages include various command-line utilities, installed by default to /usr/bin.
These utilities provide a number of useful ways to access, test, and manipulate your device.

information, see "Disabling auto attach (on page 26)".
Description
Attaches the IO Accelerator and makes it available to the operating system. This creates a block device in
/dev/fio. You can then add it to ESX as a storage area. The command displays a progress bar and
percentage as it operates.
