ESXi: console commands to digging through your hba/disk/datastore configuration

Posted by jpluimers on 2019/05/07

Two posts with interesting commands to help digging through your hba/disk/datastore configurations from the console:

One day I will write a script that – per datastore – lists all the devices related to it including their HBA and LUN.

For that, I will likely need these references:

For now this works:

  • Get the list of data stores (note the Device Name column has the NAA_ID you need below):
    esxcli storage vmfs extent list
  • Get the path information to find HBA, Channel, Target and LUN:
    esxcli storage core path list --device NAA_ID
  • Get the list of HBAs:
    esxcli storage core adapter list
  • Get device details (including Model and Revision):
    esxcli storage core device list --device NAA_ID

The example below (with most important output bolded) shows a drive connected to a SAS3008 based controller which storcli cannot access (nor MegaCli), but MegaRAID Storage Manager (MSM) can.

MSM allowed me to find the serial number of the drive by the Target Transport Details value 4433221106000000 as being on Slot number 6 (which seems to indicate Target numbers are 1-based whereas LUN is 0-based).
