MSA P2000 G3: Ошибка 242 и предупреждение 204

[RDE78]

Добрый день.

С недавнего времени MSA P2000 G3 SAS стала показывать ошибку 242 и предупреждение 204. Также ругается, что CompactFlash в обоих контроллерах unhealthy.

Судя по описанию, появление этих двух событий вместе требует замену контроллеров. Полка функционирует штатно, как отрабатывает кэш при аварийном отключении не проверяли.  Карты меняли местами между собой, не помогло. 

Хотелось бы знать - дело в контроллерах или флеш-памяти? И как это проверить?

MSA P2000 G3: Error 242 and warning 204

Good afternoon.

Recently MSA P2000 G3 SAS started showing error 242 and warning 204. It also swears that CompactFlash in both controllers is unhealthy.

Judging by the description, the occurrence of these two events together requires the replacement of controllers. The shelf functions normally, how the cache works during an emergency shutdown was not checked. The cards were swapped among themselves, it did not help.

I would like to know - is it about controllers or flash memory? And how can you check this?

The 2 events described 242 and 204 are events around the NV storage device on the controllers, this is a Compact Flash card.  These CF cards are used to store the data which is in CACHE during a power outage.  CF cards have a limited lifespan and likely just need to be replaced.  By default, while the CF card is faulty the controller will go into a WRITE-THROUGH mode where data will be written to HDD before a response is sent to the host.  This effects performance.  
A replacement PN from HPE is:  768079-001  Compact Flash Card
You can see the replacement parts on https://partsurfer.hpe.com  I used the part number AP837A to find the CF card replacement number.

Thank you for your reply, replacing the card helped.
