writes to a drive that is in a RAID array and if the write operations are rejected, the array becomes
exposed. To support normal write operations, the drive must be replaced.
Replacement of the mainstream SSD might not be covered by the system's level of service

mainstream SSDs, see "Mainstream solid-state drives" on page 40. This ends the procedure.
9. The mainstream SSD is nearing the limit for the number of write operations that are supported. No
service action is required currently.
Note: After the mainstream SSD reaches the limit for the number of write operations that are
supported, write operations to the SSD become slower over time, and at some point the SSD becomes
a read-only drive. To support normal write operations, the drive must be replaced. Replacement of the
mainstream SSD might not be covered by the system's level of service entitlement, depending on the
terms and conditions of the system. For more information about mainstream SSDs, see "Mainstream
solid-state drives" on page 40. This ends the procedure.
