-d -t driver_name

Re-attaches the driver module to the attach chain. This command should only be run

if a previous olrad -d -u driver_name operation failed, so as to not leave the

driver in detached state. The driver name should correspond to the name shown in

the ioscan output.

This option is provided for driver developers only. It will not work as a standalone

command and can only be invoked from the "DLKM (Dynamically Loadable Kernel

Module)"

unload context. Refer to the Driver Development Guide (DDG) available at

http://www.hp.com/go/hpux_ddk

for more details on DLKM.

-d -u driver_name

Detach the driver from the attach chain and delete all the active interfaces claimed by

the speciﬁed driver module. If this command fails,

olrad -d -t driver_name

should be executed to re-attach the driver. The driver name should correspond to the

name shown in the

ioscan output. Critical Resource Analysis is run to ensure that

the removal of the driver module will not cause any disruption to the system opera-

tion.

-e slot_id Lists the affected slot IDs for the speciﬁed slot.

-F Displays the output in machine readable format. It can be used with the following

options: -q, -L, -c, -h, and -v.

-f The -f option, if speciﬁed, overrides the "data critical" errors returned by CRA. It is

important to note that olrad will not allow "system critical" errors to be overridden

and that olrad automatically overrides "warnings".

Irrespective of whether

-f is speciﬁed or not, Critical Resource Analysis (CRA) rou-

tines are run before an OLA/R/D operation, to ensure that the current OLA/R/D

operation does not interrupt the normal operation of the system; in other words, to

identify "critical" errors.

The "data critical" errors are typically not critical to the system, but they may be criti-

cal to the user. Hence, the user needs to decide whether or not to use the

-f

option

for overriding these types of errors.

-g hw_path Displays the slot ID for the speciﬁed device or interface hardware path.

-h slot_id Displays the hardware paths of the interface node(s) for the speciﬁed slot.

-I flag slot_id Controls the state of the Attention LED for the given slot. The valid values for this

ﬂag option are: ATTN (LED blinking) and OFF. Based on the ﬂag value, the slot

Attention LED is set to the appropriate state. The ﬂags are not case-sensitive.

-K cell_hw_path Veriﬁes that all the I/O interfaces under the speciﬁed Cell are inactive and have been

de-conﬁgured from the Cell. (This is a pre-requisite for performing a Cell-OnLine

Delete or Cell-OLD operation). Refer to parolrad (1M) for more details regarding the

Cell-OLD operation.

-L Displays the status of all non OLA/R/D capable slots in the system. In the output,

slots with the same bus number share the same PCI Bus. Output ﬁelds are detailed

below; some descriptions are platform dependent. N/A means Not Applicable.

On systems with non OLA/R/D capable PCI-Express slots, the output ﬁelds are

slightly varied. See the PCI Express Based Slots section below for detailed descrip-

tions of the ﬁelds displayed for such slots.

Slot displays the slot_id .

Path displays the slot_hw_path .

Bus Number identiﬁes the I/O Bus corresponding to the slot.

Max Spd displays the maximum operating speed of the PCI Bus attached to the slot.
