Topic FC4-16IP iSCSI Blade for the 4/256 SAN Director Firmware upgrade/ downgrade Fabric OS-CLI commands Distance mode Description • Do not insert the Blade until the system is running Fabric OS 5.2.1b or later. • iSCSI virtual target creation involves adding LUNs to the virtual targets. The user discovers the LUNs by executing the fclunquery command. Testing has revealed that some devices do not respond properly to the LUN query. The user will need to use tools from the array vendor to determine LUN information required for iSCSI target creation. • Any uppercase letters used for the CHAP user name will be transformed into lowercase. • Users may install up to four FC4-16IP iSCSI blades per 4/256 SAN Director chassis, or any combination of up to four blades (FC4-16IP and B-Series MP Router blades), not exceeding the individual Blade limit per chassis. Valid combinations include: • Three FC4-16IP blades + one B-Series MP Router Blade • Two FC4-16IP blades + two B-Series MP Router blades • One FC4-16IP Blade + two B-Series MP Router blades • Two FC4-16IP blades + one B-Series MP Router Blade • When upgrading from Fabric OS 5.1.x to 5.2.x or 5.3.x, if two or more inter-fabric links (IFLs) connect to an edge fabric, one IFL will stay online and the other IFLs will go online and offline. This will cause a temporary traffic disruption going from multiple IFLs to one IFL and then back to multiple IFLs. This is due to the new front domain consolidation feature in Fabric OS 5.2.0, where the IFLs connected to the same edge share the same front domain. • When downgrading from Fabric OS 5.3.x or 5.2.x, FC traffic will be disrupted if there is front domain consolidation prior to the downgrade, even in the case of a single IFL. • Upon firmware download the FC4-16IP Blade does not preserve disabled GE_Ports in disabled state. If you want to retain GE_Ports in a disabled state across firmware download, you must configure them as persistently disabled. • Obsolete commands include slotOff and slotOn; use slotPowerOff and slotPowerOn instead. The portLogPortShow command is also now obsolete. • This release does not support underscore (_) as part of the name for dd and ddset in the iscsicfg command. • When performing a configdownload, you may receive a message stating "configDownload not permitted." This indicates that an invalid parameter was passed to the switch. The invalid parameter could be from a switch security policy, such as the nl password policy, or the NTP server address. This causes a partial nl configuration to be downloaded onto the switch. For example, when an NTP server address is invalid, configdownload fails nl and all data processed prior to the NTP server address data had already been nl saved in the switchand cannot be backed out. To fix the problem, correct the nl invalid parameter and re-issue the configdownload command. Distance setting is not persistent. After a configuration uploads and downloads, distance settings reset and the desired distance is shown as 0. 12
