Symptom Cannot set up mutual CHAP.
Probable cause and recommended action
A CHAP name that matches the IQN of an iSCSI initiator is treated differently in the CHAP database.
When a CHAP name is set to the IQN of an iSCSI initiator, it will be used for initiator CHAP during
mutual CHAP login.
Symptom After an iSCSI host logs out of a target, it cannot log in to that target again.
Probable cause and recommended action
There is an inconsistency in the iSCSI database.
Check using the iscsiCfg - -show fabric command.
Make sure the aggregated state is in sync.
If it is not in sync, fix the inconsistency and perform a commit using the iscsiCfg - -commit all
command.
Symptom iSCSI host can discover targets, but cannot log in to them.
Probable cause and recommended action
Zoning is enabled, but iSCSI virtual initiators are not in the same zone as the targets.
Check zoning using the cfgShow command.
Make sure iSCSI virtual initiators are in the same zone as the targets. Display the port WWN of the
iSCSI virtual initiators using the nsShow command.
