alertAction: "The flash disk has failed. A white cell
locator LED has been lit to help locate the affected cell. Please replace the flash disk. If the flash disk is used for flash cache, then flash cache will
be disabled on this disk thus reducing the effective flash cache size. If the flash disk is used for flash log, then flash log will be disabled on this
disk thus reducing the effective flash log size. If the flash disk is used for grid disks, then Oracle ASM rebalance will automatically restore the data
redundancy. Detailed information on this problem can be found at ttps://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=1113023.1
Automatic Service Request has been notified with Unique Identifier: af386c6b-c9b9-4763-a1d9-ce7351af81aa. Diagnostic package is attached. It is also accessible at
