    This may be because there may be a VMFS volume already created on this disk. Or this disk is already used as RDM.

    To reinitialize the iSCSI configuration:
    1. Log in to the ESX/ESXi host as the root user.
    2. Run this command to disable the Software iSCSI initiator:

      # esxcfg-swiscsi -d

    3. In the ESX/ESXi host, rename all files in the /etc/vmware/vmkiscsid folder . This folder has these files:

      • initiatorname.iscsi
      • iscsid.conf
      • vmkiscsid.db
      To rename the files, run these commands:

      # mv initiatorname.iscsi initiatorname.iscsi.old
      # mv iscsid.conf iscsid.conf.old
      # mv vmkiscsid.db vmkiscsid.db.old

      Additional files, such as vmkiscsid.db-journal, if present, must also be renamed.

    4. Reboot the ESX/ESXi host.
    5. After rebooting the host, run this command to re-enable the Software iSCSI initiator:

      # esxcfg-swiscsi -e

      Note: A new software iSCSI initiator ID is generated. This IQN needs to be added to the SAN.

    6. Run this command to scan for disks that are available through the Software iSCSI interface:

      # esxcfg-swiscsi -s

    Since you're messing with CHAP reboot the host and then check your logs if it doesn't come back.
