Issue/Introduction

Symptoms:
When connecting an ESXi host through iSCSI (software or hardware) to a Storage Array, you may experience these symptoms:
  • No targets are visible.
  • LUNs are not visible on the ESXi host
  • A rescan fails to pick up any storage devices.
  • Storage devices are visible from one or more other hosts.


Environment

VMware ESXi 6.5.x
VMware vSphere ESXi 7.x
VMware vSphere ESXi 8.0.x
VMware ESXi 6.7.x

Resolution


This issue occurs when the IQN of the ESXi/ESX host is not permitted to access the target. This can occur if:
  • Multi-host volume access is not enabled for that volume
  • The IQN or IP address of the ESXi/ESX host is not listed in the Access Control List (ACL) for that volume
  • CHAP authentication is incorrect
  • The SAN/target IP address is entered incorrectly in the Dynamic Discovery tab

For information on checking these settings, see the Configuration Guide for your EqualLogic storage array at http://www.equallogic.com/support/.

When the settings have been changed, perform a rescan on the ESXi/ESX host. See Performing a rescan of the storage on an ESX/ESXi host (1003988) for details.

If vobd returns an iSCSI error, please refer to Target information not updated by iSCSI array
