  • Page 52: If The Controller Has Failed Or Does Not Start, Is The Cache Status Led On/blinking

    To preserve the existing data stored in the CompactFlash, you must transport the CompactFlash from the failed controller to a replacement controller using a procedure outlined in the HP P2000 G3 MSA System controller replacement instructions, shipped with the replacement controller. Failure to use this procedure will result in the loss of data stored in the cache module.
