Interface Card OL* Support Guide

The Activation and De-activation of a cell as part of Dynamic nPartition operation are performed
using the parolrad(1M) command.
WARNING! It is possible for an I/O Chassis to be in inactive state, either because the I/O Chassis
is connected to an inactive cell or because the I/O Chassis has been de-configured using the olrad
chassis delete operation. The only supported procedure for adding/removing/replacing of PCI
I/O cards in such an inactive I/O chassis is as follows:
1. Power down the cell attached to the I/O chassis by entering the following command:
frupower -f -c cell
or using the MP prompt.
2. Add or remove I/O cards to or from I/O chassis, using latches to disable slot power if
necessary.
3. Power up the attached cell entering the following command:
frupower -o -c cell
or using the MP prompt.
Users must not attempt to add/remove/replace I/O cards in an inactive chassis in any other way
as the I/O slots containing these cards can still be in powered on state.
NOTE: The identifier of the cell specified as argument to olrad and parolrad commands
are of different formats. While the parolrad command allows the cell to be specified as either
a global slot number or a cabinet/local slot number pair, the olrad command allows the cell to
be specified only as hardware path of the cell as seen in the ioscan command.
Turning the Attention LED to BLINK or OFF
To turn the Attention LED to BLINK, enter the following command:
#/usr/bin/olrad -I ATTN slot_ID
To turn the Attention LED to OFF, enter the following command:
#/usr/bin/olrad -I OFF slot_ID
Options, Scripts, and Logging
This section describes additional olrad options, olrad scripting capabilities, and olrad logging.
Options
Following are details about additional olrad options. See the olrad(1M) manpage for a complete
list of options and usage.
-a slot_id
Prepare to add a card to the system at the specified slot. A CRA is run to ensure
that the card addition will not cause disruption in the functioning of the system.
The driver scripts (pref_replace and prep_replace) for affected slots (if
any) are run and the drivers associated with the affected slots are suspended.
The slot power is turned OFF, and the Attention LED at the corresponding slot
is set to BLINK.
-A slot_id
After a card is physically added, the slot power is turned ON and the drivers
associated with all affected slots are resumed. An ioscan is run and if the card
is claimed, the driver scripts post_add for the current slot and post_replace
for affected slots if any are run and the Attention LED at the corresponding slot
is turned OFF.
