| Title | Appliance Read Only in PowerStore - V1.0 and recovery process |
| Alert ID | DATA_PATH_APPLIANCE_READ_ONLY_ENTER |
| Description | A PowerStore appliance detects corruption during the user data flush after attempt to inline recovery. The corruption limits the user data flush from making progress. User reads are allowed, but writes are disabled. Appliance transitions to Read-Only state. |
| Error Code | (0x00201301) |
| Resolution | Cause
During user data flush of dirty pages from Log, if Mapper detects a metadata corruption after FUA attempt to recover data, the corruption limits the user data flush from progressing. User reads are allowed, but writes are disabled. PowerStore Data Path has to transition to a read-only state to reject any new incoming Write IOs.
