IBM 2-Gigabit Fibre Channel PCI, Инструкция по установке и использованию

Страница: 34 / 52

have sufficient memory, the maximum is 1024 for a Gigabit Fibre Channel PCI Adapter
(Type 4-S). The maximum is 2048 for a 2-Gigabit Fibre Channel PCI Adapter (Type
4-W).
If the SCSI target device is connected to the host through a SAN Data Gateway (SDG),
then this parameter cannot exceed the SDG limit of 240 (SAN Data Gateway is a
SCSI-to-Fibre Channel bridge).
Maximum Transfer Size: The default is 256 kilobytes, which is the largest single
transfer size. For tape, transfers of 2 megabytes or more are possible. The range is 256
kilobytes to 16 megabytes.
Preferred AL_PA: The preferred AL_PA (Arbitrated Loop Physical Address) value is
the address that the adapter requests at the beginning of every LIP (Loop Initialization
Process). This configuration option must be used to set a unique AL_PA for each
adapter in an Arbitrated Loop.
No two devices on a loop should have the same Preferred AL_PA. The outcome of
arbitration would be random and would result in Permanent I/O Errors.
Every device on a loop must have unique AL_PAs. To maximize efficiency, hosts must
have low AL_PAs for higher loop priorities. Targets must have higher AL_PAs for lower
priorities.
INIT Link Flags: This option is available for AIX 5.1 and later. This must be configured
for AL (Arbitrated Loop) mode.
Applying Changes to Database Only
The default is No for the Apply Changes to Database Only field. If the field is No, the
ODM database is changed and the device is unconfigured and reconfigured.
If the field is Yes, only the ODM database is changed. Configuration changes are not
applied to the device until it is unconfigured and reconfigured, or the system is
rebooted.
Information Fields
The rest of the FC Adapter’s Change/Show Characteristics screen contains the
following information:
FC Adapter: Parent FC adapter driver instance’s identification.
Description: Description of the parent FC adapter driver.
Status: Parent adapter driver’s current status. ’Available’ indicates that the driver and
its adapter are functioning.
Location: Location code of the FC adapter driver. The parent adapter driver instance
fcsX will have for its location code the first two values of this three-value location code.
For example, if the parent FC adapter driver instance (fcs0) has a location code of
20-58, all children will have the location code of 20-58-01.
