User`s guide

The replacement configuration must contain both a cache module and an HS
array controller module. The replacement HS array controller module must
have its program card removed during the insertion process. This eliminates
the possibility of prematurely starting the C_SWAP program before the
module is completely installed. Once the second controller is detected, C_
SWAP displays a restart procedure and exits. Insert the program card into
the newly replaced controller module to complete the restart procedure.
5.11.2.2 Replacing a Controller and/or Cache Module During a C_SWAP Operation
The following is an example of a C_SWAP session for an HSJ40 array controller
/cache module swap in which the replacement HSJ40 array controller is not
immediately available. After you have entered the RUN C_SWAP command,
C_SWAP prompts you as follows:
Do you have a replacement HSJ40 readily available [N]? NO
The warm swap sequence terminates, and you have to restart the routine later
when you have a replacement module.
When you have a replacement, you can restart the sequence by entering the RUN
C_SWAP command again. The system responds with the following:
Do you have a replacement HSJ40 readily available [N]? YES
1. Enter ‘‘Y’’ if you have the controller module.
*** Sequence to INSERT other HSJ40 has begun. ***
Do you wish to INSERT the other HSJ40 [N]? YES
2. Enter Y to insert the controller module. (A message about the cache module
appears only if you removed the cache module in the first place.)
Remember to reinsert the cache module if necessary.
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.
Insert the cache module, then insert the other HSJ40, WITHOUT its
program card, and press Return.
3. Insert the cache module (if applicable) and controller module now. Follow the
steps outlined in Section 5.14 to physically replace your controller module, or
in Section 5.15 to replace your cache module.
Restarting ALL ports.
Port 1 restarted.
Port 2 restarted.
Port 3 restarted.
Port 4 restarted.
Port 5 restarted.
Port 6 restarted.
The configuration has two controllers.
The Controller Warm Swap program has terminated. To restart the
