HP StorageWorks Fabric OS 5.3.0c Release Notes (AA-RWEYG-TE, November 2007)

FC4–48 port Blade for
the 4/256 SAN Director
• The HP StorageWorks 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 wil l not be able to
be downgraded earlier than 5.2.0a until the FC4–48 is removed.
• The FC4–48 Blade suppor ts 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 ports for the FC 4–48 Blade will honor that
valueaslongasitsshareareavaluesare127orless.
• Before replacing an FC4–32 Blade with an FC4–48 Blade, restore ports
16–31oftheFC4–32Blade,iftheseportsareusedforportswapping.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 back into the slot and port swap the
ports back to the port’s default setting.
• FC4–48 ports should not belong to the zone or in an admini strative domain in
which FICON devices reside.
• The FC4–48 Blade does not support loop. Private L_Ports will be shown on
these ports in switchshow, but will not participate in the fabric.
• The porttest and spinfab commands on any platform will not work on
E_Por ts connected to an FC4–48 port.
• The FC4–48 Fibre Channel port Blade is not supported to connect to the
System z env ironments via FICON channels or via FCP zLinux 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 por t blades.
• In a zoning configuration with members D and P, where P is greater than or
equal to 256, remove these configurations before dow ngrading to an earlier
firmware version (5.1.x or 5.0.x). Otherwise, the downgrade will not be HA
compatible with earlier versions.
• All zones involving the shared ports (domain, port or W WN) of an FC4-48
Blade would be treated as session based in ”interopmode 2” fabric
configuration.
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 th e 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 FC4–16I P i SCSI 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 Blad e
• Two FC4–16 IP blades + two B-Series MP Router blades
• One FC4–16IP Blade + t wo B-Series M P Router blades
• Two FC4–16IP blades + one B-Series MP Router Blade
