To enter the interrupt command mode, enter the
scope interrupt command
from FC interface command
mode. From interrupt command mode, you can specify the FC interrupt mode using the
set interrupt-
mode {intx | msi | msix}
command. The modes are as follows:
•
intx: Line-based interrupt (INTx)
•
msi: Message-Signaled Interrupt (MSI)
•
msix: Message Signaled Interrupts with the optional extension (MSI-X). This is the recommended
and default option.
To enter the FC port command mode, enter the

Command
Description
set outstanding-io-count
count
I/O throttle count, the number of I/O operations that can be pending in the vHBA at one
time. The range is 1 to 1024; the default is 512 operations.
set max-target-luns count
Maximum LUNs per target, the maximum number of LUNs that the driver will discover.
This is usually an operating system platform limitation. The range is 1 to 1024; the

set flogi-timeout msec
FLOGI timeout value, the number of milliseconds that the system waits before it tries to
log on again. The range is 1 to 255000; the default is 2000 milliseconds.
To enter FC port login command mode, enter the
scope port-p-logi

command mode. From FC port login command mode, you can enter the following commands:
Command
Description
