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.
