suspended. The target slot is powered off and the attention LED is set to BLINK at
the corresponding slot.
If the
-f option is specified, it overrides critical analysis (CRA) results. See the
description earlier for the -f option.
-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.
-f The -f option, if specified, overrides the "data critical" errors returned by CRA. It is
important to note that olrad will not allow "critical" errors to be overridden and that
olrad automatically overrides "warnings".
Irrespective of whether
-f is specified or not, critical resource analysis routines are
run before an OLA/R operation, to ensure that the current OLA/R operation does not
interrupt the normal working 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 need to decide whether or not to use the
-f option for
overriding these types of errors.
-F Displays the output in machine readable format. It can be used with the following
options:
-q, -c, -h, and -v.
-n Display the number of OLA/R capable slots in the system.
-q Displays the status of all OLA/R capable slots in the system. In the output, slots with
the same bus number are treated as shared slots.
-I flag slot_id Controls the state of the Attention LED. The valid values for this flag option are:
ATTN and OFF. Based on the flag value, the Attention LED at the corresponding slot
is set to the appropriate state. The flags are not case-sensitive.
-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.
-p flag slot_id Controls the slot power. The valid value for this flag option are: ON
and OFF. Based
on the flag set, the slot power status changes appropriately. The flags are not case
sensitive.
-C slot_id Runs critical resource analysis routine (CRA) only on the specified slot_id and display
the results. It checks for critical resources on all affected hardware paths associated
with the specified slot. It analyzes file systems, volumes, processes, networking, swap,
and dump; and generates a report of affected resources. It lists the severity levels and
their meanings.
CRA_SUCCESS no affected resources in use.
CRA_WARNINGS resources in use on affected device(s) but none are deemed
critical.
CRA_DATA_CRITICAL probable data loss, only proceed with the user’s permission.
CRA_SYS_CRITICAL likely to bring down the user’s system.
CRA_ERROR some internal CRA error encountered.
Users are advised to use this option first to check out whether the intended OLA
operation is safe and would not cause disruption in the functioning of the system.
-c slot_id Displays the device information (Device_ID, Vendor_ID, Revision_ID, etc) of all the
interface devices at the indicated slot.
-e slot_id Lists the affected slot IDs for the specified slot.
-h slot_id Displays the hardware paths of the interface node(s) for the specified slot.
-g hw_path Displays the slot ID for the specified hardware path.
-v hw_path Displays driver information, such as current state, time-out, etc.
