5. Enter the following command:
HS x > RUN C_SWAP
The system responds with:
Controller Warm Swap, Software Version -V2.0
*** Sequence to REMOVE other HSJ40 has begun. ***
Do you wish to REMOVE the other HSJ40 Y/N [N]? YES
6. Enter ‘‘Y’’ to continue the procedure.
Will its cache module also be removed Y/N [N]? YES
7. Enter ‘‘Y’’ only if you are removing the controller’s cache module as well.
After you answer the controller/cache module identity prompts, C_SWAP fails
over the I/O for the failed controller to the controller running C_SWAP. The
failover operation is complete when the green indicator (reset LED) on the HS
array controller module to be replaced stays lit. C_SWAP then performs a bus
quiesce operation and prompts you to remove the specified modules, as shown
in the following example:
Killing other controller.
Attempting to quiesce all ports.
Port 1 quiesced.
Port 2 quiesced.
Port 3 quiesced.
Port 4 quiesced.
Port 5 quiesced.
Port 6 quiesced.
All ports quiesced.
Remove the other HSJ40 (the one WITHOUT a blinking green LED) within 5 minutes.
Time remaining 4 minutes, 50 seconds.
CAUTION
Do not remove the controller with the blinking green LED reset (//)
button.
8. You have 5 minutes to perform the remove operation for a controller/cache
module swap, and 2 minutes for the controller-only swap, following the steps
described in Sections 5.12 and 5.13.
If you do not complete the removal in this time, the configuration that was
running when you started is restored, all ports are restarted, and C_SWAP
exits. All ports remain quiesced during this interval. If you have not inserted
a replacement controller or cache module, you are prompted as follows:
Do you have a replacement HSJ40 readily available [N]?
Return
No OTHER HSJ40 immediately available, program exiting.
If you enter NO or press Return in response to this prompt, C_SWAP exits
with the HS array controller in the failed-over configuration. If you enter
YES, you are given an additional time interval to perform the remove/replace
operation.
