Working with Diagnostic Commands
Setting a Boot Parameter
You use the
diagnostic set boot_parameter
command to set
a controller boot-time parameter to a specific value. Under normal
conditions, boot-time parameters are not set. You usually set a boot-
time parameter at the request of a technical support person.
Before setting a boot-time parameter, use the
diagnostic show
boot_parameter
command to display information about the
desired parameter. Due to the unique use of boot-time parameters,
an example
diagnostic show boot_parameter
command is
not provided in this document.
To set a boot-time parameter on an open controller, use the
diagnostic set boot_parameter
command. Due to the
unique use of boot-time parameters, an example
diagnostic set
boot_parameter
command is not provided in this document.
After running the
diagnostic set boot_parameter
command
to set a boot-time parameter, use the
diagnostic show
boot_parameter
command to display the boot-time parameter
value.
Setting the Interrupt Count
You use the
diagnostic moderation set count
command to
set the default interrupt count on a controller. The interrupt count is
the number of outstanding I/O requests on the controller needed
before an interrupt delay time takes effect, sending an interrupt to
the host computer.
Before setting the interrupt count, use the
diagnostic
moderation show count
command to display the current
interrupt count, as in the following example. In the example, the
The moderation count is currently set to
line indicates that the
interrupt count is set to 500 I/O requests.
HPN0> diagnostic moderation show count
Executing: diagnostic show Count
The moderation count is currently set to 500.
To set the interrupt count, use the
diagnostic moderation set
count
command, as in the following example. In the example, the
diagnostic moderation set count
command sets the interrupt count
to 100 I/O requests.
