This note is about Objective 1.1.S.2: Verify SAN LUN Accessibility. There are two simple ways to determine if a SAN LUN is accessible.
- See if you can browse the datastore in the VI client. See if you can get in the folder containing a virtual machine on that datastore (LUN).
- On the command line, list the contents of the
/vmfs/volumesdirectory. Then navigate to the LUN in question and see if the vm files show up.ls -l /vmfs/volumescd /vmfs/volumes/LUN_3(for example).
