7.8 Disk Statistics
The page shows information on the disks in the system.
Figure 23 Disk Statistics
Each disk displays its Reads, Writes, Others, Transfer Retries, and Media Retries. If a disk is generating errors, it may fail sometime in the future. RAID 5 configurations should distribute reads and writes evenly among all of the drives.
