■
If you see
value ’full’
underneath the
default-hotswap-mode
line, then at
least one of the I/O slots in the Netra CT server is set to full hot-swap. You must
look at the entries for individual I/O slots to determine if they are set to basic or
full hot-swap mode:
■
If you see
value ’enabled’
underneath a
<slot # -autoconfig>
line, then
that slot is set to full hot-swap.
■
If you see
value ’disabled’
underneath a
<slot # -autoconfig>
line, then
that slot is set to basic hot-swap.
5.2.3.2 Enabling Basic Hot-Swap on I/O Slots
All of the I/O slots in the Netra CT server are set to full hot-swap by default. You
can disable full hot-swap on one or more I/O slots, bringing those slots to a basic
hot-swap state. That means that if an I/O board becomes faulty and needs replacing,
you must manually deactivate the I/O slot using the
cfgadm
utility before you can
remove the board, then you must manually reactivate the I/O slot after replacing the
board.
To disable full hot-swap on one or more I/O slots, changing those slots to a basic
hot-swap state, as superuser, by enter:
Note – Whenever you reboot or power your server on and off, the hot-swap states
revert back to the default full hot-swap state for all I/O slots. If you want one or
more I/O slots set to the basic hot-swap setting, you must manually reset the I/O
slots after rebooting or powering your server on and off.
Deactivating a Hot-Swappable FRU
To deactivate an I/O board in a basic hot-swap state, as superuser, enter:
where ap_id is the attachment-point ID. For example, to deactivate an I/O board in
slot 4, as superuser, enter:
# cfgadm -x disable_autoconfig
ap_id
# cfgadm -c unconfigure
ap_id
# cfgadm -c unconfigure IO-4
