Re: How to map a RDM to a VM via the CLI

Thank you for your answer, but you DID NOT create an RDM.  Your example creates a virtual disk.

from link: http://www.vm-help.com/esx40i/manage_without_VI_client_6.php

"vmkfstools -c 255G -d eagerzeroedthick -a lsilogic IOMETER.vmdk "

With that type of virtual disk then the command

     "vim-cmd vmsvc/device.diskaddexisting 272 /vmfs/volumes/datastore1/IOMETER/IOMETER.vmdk 0 1"

does work.

However, I am creating an RDM, which is needed for our testing of I/O traffic.  I use the command

vmkfstools  -r  /vmfs/devices/disks/naa.60060160cd103300b2678da7b981e211 /vmfs/volumes/datastore3/Linux1Auto1/Linux1Auto1_3.vmdk

This creates the RDM vmdk files:

-rw-------    1 root     root         5368709120 Mar  6 10:10 Linux1Auto1_3-rdm.vmdk
-rw-------    1 root     root                487 Mar  6 10:10 Linux1Auto1_3.vmdk

However, when trying to add the disk to a VM this is what occurs.

     vim-cmd vmsvc/device.diskaddexisting 2 /vmfs/volumes/datastore3/Linux1Auto1/Linux1Auto1_3.vmdk 0 1
     Reconfigure failed

This corresponds to the vim-cmd documentation that states it does not work with RDMs

So, once again I ask VMware.  How do you add an RDM disk to a VM with a CLI command?

Thank you.
