The dialog boxes shown in DiskSuite Tool use the following terms when the state of the components is reported.
OK - The component is operating properly.
Resyncing - The component is in the process of resyncing (copying) the data.
Erred - The slice has encountered an I/O error or an open error. All reads and writes to and from this slice have been discontinued. See the Solstice DiskSuite 4.2.1 User's Guide for information on slice replacement.
Last erred - The slice has encountered an I/O error or an open error. However, the data is not replicated elsewhere due to another slice failure. I/O is still performed on the slice. If I/O errors result, the mirror or RAID5 I/O will fail. See the Solstice DiskSuite 4.2.1 User's Guide for information on slice replacement.
