11 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: defZone --show 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: iscsiCfg - -show tgt 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.

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:
defZone --show
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:
iscsiCfg - -show tgt
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:
iscsiCfg - -show lun
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:
iscsiCfg - -show fabric
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.
