HP StorageWorks Fabric OS 5.2.0b Release Notes (AA-RWEYB-TE, February 2007)

FC4–48 port blade for the
4/256 SAN Director
• The HP StorageW orks 4/48 SAN Director blade requires FOS 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. After the FOS has been updated and a
FC4-48 has been installed the FOS will not be able to be downgraded
lower than 5.2.0a until the FC4–48 is removed.
• The FC4–48 blade only supports core PID (fmt 1) in Secure FOS.
• NPIVsupportedonlyinports0to15oftheFC4–48blade.
• Long distance Buffer Credits. The FC4–48 has 560 credits available for
long distance. The FC4–32 blade has 624 credits available for long
distance.
• Port mirroring. The FC4–48 is restricted to one F-port mirroring allowed
between shared areas for ports 1 6-47. On the FC4–48, port mirroring
on ports 0-15 behaves the same as the FC4–32 blade.
• configure comman d only gives a maximum login per port setting. The
command allows over 127, where ports for the FC4-48 blade will honor
that value as long as its share areas values are 1 27 or less.
• Before replacing FC4–32 blade with FC4–48 blade, restore ports 16
– 31 of the FC4-32 blade if t hese por t s are used for port swapping.
Failure to do so will fault the FC4-48 blade. The only way to restore back
to original settings is to add the FC4-32 blade back in to the slot and
port swap the por ts back to the port’s default setting.
• FC4-48 ports should not belong to the zone or in an administrative
domain in which FICON devices are present.
• 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_Ports connected to a 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 zLinux on System
z. To use the 4/256 SAN Director to attach to the Sy stem z env ironment,
please use the FC4-16 or FC4-32 Fibre Channel por t b lades.
• InazoningconfigurationwithmembersDandP,wherePisgreaterthan
or equal to 256, remove these configurations before downgrading to a
lower firmware version (5.1.x or 5.0.x). Otherwise, the downgrade will
not be HA compatible with earlier versions.
FC4-16IP iSCSI blade for the
4/256 SAN Director
NOTE:
At the time of this release, HP does not support the FC4-16IP iSCSI
blade. Check h
ttp://www.hp.com for the latest supported hardware .
• Do not insert the blade until the system is running Fabric OS 5.2.0a.
• 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 upper case letters used for the C HAP user name will be transformed
to lower case.
