  • 1.  What LUN does an RDM point to?

    Posted Aug 12, 2013 05:45 PM

    I am in the process of updating some home grown ESX 4.1 U3 service console disaster recovery scripts to run in the vMA with ESX 5.1 U1.

    I have run into an issue.

    Under the service console on 4.1, I could use vmkfstools --queryrdm to determine what LUN (ok, vml, but it amounts to the same thing) an RDM pointed to.  In the vMA version of vmkfstools, the --queryrdm option is specifically not supported.  In the absence of this option, how do I determine what LUN an RDM points to?  Is there some way to use any of the metadata in the .vmdk file to determine this?

    You can run the command directly from the console (ESXi Shell or SSH) of an ESXi host.

    Yes, I could, and I may have to consider that if a better way doesn't present itself.  The problem is that I am trying to do this from within a Perl script that gets automatically run every day.  Perl no longer seems to exist in the ESXi shell and and neither does crontab.

    I would prefer to find some way of doing this from the vMA...
