10 Zoning Zoning The following issues address zoning problems that can occur in iSCSI. Symptom No DDSet or zoning configuration enabled and iSCSI host cannot discover any targets. Probable cause and recommended action Default zoning is set to no access. Check default zoning using the defZone --show command. Either create a zoning configuration or set default zoning to All Access using the defZone command. Symptom No DDSet or zoning configuration enabled and iSCSI host cannot discover any targets. Probable cause and recommended action Virtual targets have not been created, virtual targets are not online, or changes have not been committed. Check virtual targets using the iscsiCfg - -show tgt command. Make sure all virtual targets are reported as online and committed. If the virtual target is offline, either no LUNs have been mapped to that virtual target or the physical LUN is offline. If the virtual target is not committed, then use the iscsiCfg - -commit all -f command. The -f operand is use to force the commit operation, in which case uncommitted changes on other switches are erased. Symptom No DDSet or zoning configuration enabled and iSCSI host cannot discover any targets. Probable cause and recommended action No LUNs have been assigned to the virtual targets. Check LUN mapping using the iscsiCfg - -show lun command. Make sure LUNs have been assigned to the virtual targets. Assign LUNs using the iscsiCfg --add lun command. Symptom No DDSet or zoning configuration enabled and iSCSI host cannot discover any targets. 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 Changes made to the iSCSI database do not appear on iSCSI hosts. Probable cause and recommended action The DDSet has not been enabled or the database has not been committed. Check the currently enabled DD Set using iscsiCfg - -show ddset command. Make sure it is reported as enabled and committed. Fabric OS Troubleshoot and Diagnostics Guide 73 53-1001340-01
