HP StorageWorks Fabric OS 5.3.0 Release Notes (AA-RWEYD-TE, July 2007)

FC4–48 port blade for
the 4/256 SAN Director
• The HP StorageW orks 4/48 SAN Director blade requires a minimum of Fabric
OS 5.2.0a. Do not insert the FC4–48 blade into the 4/256 chassis until
the chassis is running Fabric OS 5.2.0a or later. After Fabric OS has been
updated and an FC4–48 has been installed, the Fabric OS will not be able to
be downgraded earlier than 5.2.0a until the FC4–48 is removed.
• The FC4–48 blade supports only core PID (fmt 1) in Secure Fabric OS.
• NPIV is suppor ted only in ports 0 to 15 of the FC4–48 blade.
• Regarding long distance buffer credits, the FC4–48 has 560 credits available
forlongdistance. TheFC4–32bladehas624creditsavailableforlong
distance.
• Regarding port mirroring, the FC4–48 is restricted to one F-port mirroring
allowed between shared areas for ports 16–47. Port mirroring on ports 0–15
behaves the same as the FC4–32 blade.
• The configure command gives only a maximum login per port setting. The
command allows over 127, where por ts for the FC4–48 blade will honor that
valueaslongasitsshareareavaluesare127orless.
• Before replacing an FC4–32 b lade with an FC4–48 blade, restore ports
16–31 of the FC4–32 blade, if these ports are used for port swapping. Failure
to do so will fault the FC4–48 blade. The only way to restore the original
settings is to add the FC4–32 blade b ack into the slot and port swap the
ports back to the por t’s default setting.
• FC4–48 ports should not belong to the zone or in an administrative domain in
which FICON devices are present.
• The FC4–48 blade does not support loop. Private L_Ports will be shown on
these ports in switchshow, but will not partici pate in the fabric.
• The porttest and spinfab commands on any platform will not work on
E_Ports connected to an FC4–48 port.
• The FC4–48 Fibre Channel port blade is not supported to connect to the
System z environments via FICON channels or via FCP zLinu x on System z.
To use the 4/256 SAN Director to attach to the System z environment, use
the FC4–16 or FC4–32 Fibre Channel port blades.
• In a zoning configuration with members D and P, where P is greater than or
equal to 256, remove these configurations before downgrading to an earlier
firmwareversion(5.1.xor5.0.x).Otherwise,thedowngradewillnotbeHA
compatible with earlier versions.
FC4–16IP iSCSI blade for
the 4/256 SAN Director
(continued)
• 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 vir tual 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.
• AnyuppercaselettersusedfortheCHAPusernamewillbetransformedinto
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
