how to Remove unmounted/inaccessible datastore from ESXi Host

• Login to esxi with ssh

• Find the datastore id using:

    esxcli storage core device list

• Now  find out „naa.“ of unmounted/inaccessible datastore

• remove the lun id:

 esxcli storage core device detached remove -d naa.600000e00d00000000010bc100000000

• rescan hba:

   esxcli storage core adapter rescan --all

Restart iscsi software service in esxi

To restart the software iSCSI stack ,we have to follow below steps

1. Disable the software iSCSI :
   esxcfg-swiscsi -d
2. Terminate the software iSCSI processes with the command:
   esxcfg-swiscsi -k
   
   In some cases, the iSCSI stack is in an unresponsive state and does not terminate on this command. If this happens, you must find the process ID and issue a terminate command directly to the operating system for this process.
   1. Obtain the process ID for the vmkiscsi processes with the command:ps ax | grep vmkiscsid
   2. Terminate the process with the command:
      kill <process ID>
3. Enable the software iSCSI configuration with the command:
   esxcfg-swiscsi -e
4. Perform a rescan of the software initiator with the command:
   esxcfg-rescan vmhba40
