Removing A Controller And Cache Module - HP StorageWorks HSG80 Array Controller V8.7 Maintenance And Service Manual

Removing a Controller and Cache Module

Use the following steps to remove a controller and supporting cache module in a
dual-redundant controller configuration.
CAUTION: ESD can easily damage the controller, cache module, or DIMM. Wear a
snug-fitting, grounded ESD wrist strap.
1. Connect a PC or terminal to the maintenance port of the operational controller.
The controller connected to the PC or terminal becomes "this controller"; the
controller being removed becomes the "other controller."
2. Disable failover and take the controllers out of dual-redundant configuration with
one of the following commands:
SET NOFAILOVER
or
SET NOMULTIBUS_FAILOVER
3. Remove the program card ESD cover and program card from the "other
controller." Save them in an antistatic bag or on a grounded antistatic mat for use
with the replacement controller.
4. Start the field replacement utility (FRUTIL) with the following command:
RUN FRUTIL
5. Enter N(o) to the question about replacing the cache battery.
6. Enter option 1 to remove a controller or cache module.
7. Enter option 3 to remove the "other controller" and cache module.
8. Enter Y(es) to confirm the intent to remove the "other controller" and cache
module.
CAUTION: Wait for FRUTIL to quiesce the device ports—indicated by an "All device
ports quiesced" message. Failure to allow the ports to quiesce might result in data
loss. Quiescing might take several minutes.
IMPORTANT: A countdown timer allows a total of four minutes to remove both the
controller and cache module. After four minutes, "this controller" exits FRUTIL and resumes
operations. If this happens, return to step 4 and proceed.
9. Remove the "other controller:"
