Irrespective of whether -f is specified or not, Critical Resource Analysis (CRA) routines
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 "criti-
cal" errors.
The "data critical" errors are typically not critical to the system, but they may be critical
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.
-n Display the number of OLA/R/D capable slots in the system.
-P flag slot_id Controls the state of the power indicator. Currently, the only valid value for this flag
option is:
RAIL. The -P option can be used with RAIL to set the power indicator to
follow the specified slot’s power state; in other words, the power indicator is turned solid
ON if the slot power is ON, or the power indicator is turned OFF, if the slot power is
OFF. The flag is not case sensitive.
-q Displays the status of all OLA/R/D capable slots in the system. In the output, slots with
the same bus number are treated as shared slots. Output fields are detailed below;
some descriptions are platform dependent.
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.
Spd displays the current operating speed of the PCI Bus attached to the slot. The card
inserted into the slot determines the current operating speed, together with the capabil-
ity of the slot’s PCI Bus.
Pwr displays the slot power status.
Occu displays whether the slot is occupied or not.
Susp displays if the card in the slot is suspended or not.
Driver(s) Capable displays the OL* capability of the interface driver/s that
claimed the PCI device/s present in the slot. OLAR field displays whether the interface
driver/s are capable of OnLine Add/Replace operations.
OLD field displays whether the
interface driver/s are capable of OnLine Deletion operation.
Max mode displays the maximum operating mode of the PCI Bus attached to the slot.
Mode displays the current operating mode of the PCI Bus attached to the slot. The
card inserted into the slot determines the current operating mode, together with the
capability of the slot’s PCI Bus. PCI and PCI-X are examples of different operating
modes.
-R slot_id Post Replace phase. The target slot power is turned ON. The suspended drivers are
resumed and the driver scripts (post_replace ) for the current slot and the affected
slots (if any) are run. The attention LED at the corresponding slot is set to OFF.
On systems with the capability to handle certain PCI hardware errors during the opera-
tion of PCI I/O cards, the post replace phase can be used to attempt recovery of the PCI
card and corresponding I/O slot from such errors.
-r slot_id Prepare to replace a card on the system at the specified slot. Critical Resource Analysis
(CRA) is run to ensure that the current card replacement on the system will not cause
disruption in the functioning of the system. The driver scripts (pref_replace and
prep_replace ) for the affected slots (if any) and the current slot are run. The
drivers associated with the current slot and affected slots are suspended. The target
slot is powered off and the attention LED is set to BLINK at the corresponding slot.
