Resolving iSCSI error messages on the storage system

There are a number of common iSCSI-related error messages that might display on your storage system console.

The following table contains the most common error messages, and instructions for resolving them.

Message Explanation What to do
ISCSI: network interface identifier disabled for use; incoming connection discarded The iSCSI service is not enabled on the interface. You can use the iscsi interface enable command to enable the iSCSI service on the interface.

For example:

iscsi interface enable e9b
ISCSI: Authentication failed for initiator nodename CHAP is not configured correctly for the specified initiator. Check CHAP settings.
  • Inbound credentials on the storage system must match outbound credentials on the initiator.
  • Outbound credentials on the storage system must match inbound credentials on the initiator.
  • You cannot use the same user name and password for inbound and outbound settings on the storage system.
ifconfig: interface cannot be configured: Address does not match any partner interface. or Cluster monitor: takeover during ifconfig_2 failed; takeover continuing... A single-mode interface group can be a partner interface to a standalone, physical interface on a cluster partner. However, the partner statement in the ifconfig command must use the name of the partner interface, not the partner's IP address. If the IP address of the partner's physical interface is used, the interface is not successfully taken over by the storage system's interface group.
  1. Add the partner's interface using the ifconfig command on each system in the HA pair. For example:
    system1> ifconfig vif0 partner e0a
    
    system2> ifconfig e0a partner vif0
  2. Modify the /etc/rc file on both systems to contain the same interface information.
