10 Authentication Enable an appropriate DDSet using the iscsiCfg - -enable ddset command. Check for open transactions using the iscsiCfg - -show transaction command. Commit any open transactions using the iscsicfg - -commit all -f command. Authentication Symptom Symptom 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. 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. 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. 74 Fabric OS Troubleshoot and Diagnostics Guide 53-1001340-01

Enable an appropriate DDSet using the
iscsiCfg - -enable ddset
command.
Check for open transactions using the
iscsiCfg - -show transaction
command.
Commit any open transactions using the
iscsicfg - -commit all -f
command.
Authentication
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.
