The following actions should be done prior to adding or replacing
a card to provide valuable information about the slots and potential
affects of disabling one.
The olrad -q command provides details and the status of all OL* capable
slots in the system. In the output, slots with the same bus number
are treated as shared slots.

Critical
Resource Analysis
Users are advised to use this option first to check out whether
the intended OL* operation is safe and would not cause disruption
of the functioning of the system. Perform a CRA against the slot
of interest.
Runs critical resource analysis routine 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.
The
CRA 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.
The syntax for this option is olrad -C slot_id.
