Random ESXi 5 CLI Tips and Shortcuts #2

by admin

One task that crops up often when working with ESXi host storage from the command line is how to match up VMFS datastores to the storage device they live on. There are a couple of ways to find this information from the CLI, either directly or by using a vMA. Using ESXCLI you can get the information by running:

~ # esxcli storage vmfs extent list
Volume Name           VMFS UUID                            Extent Number  Device Name                                           Partition

Alternatively, you can use vicfg-scsidevs from a vMA (or esxcfg-scsidevs if run locally):

~ # esxcfg-scsidevs -m
mpx.vmhba1:C0:T2:L0:1                                            /vmfs/devices/disks/mpx.vmhba1:C0:T2:L0:1                                  4ff9dae8-858c7e95-12f0-000c29e8410a  0  TestVOL
