Note
Identifying a Failed Disk Unit
GDS Management View shows disks with I/O errors by indicating them with red disk icons. In addition, if an I/O error occurs, 1 (one) is given as a value in the E field displayed with the sdxinfo -e long command.
However, for hardware-related errors, identify the failed parts based on log messages of disk drivers stored in the /var/adm/messages file and such.
If GDS Management View and the sdxinfo command indicate the invalid status of slice data (invalid or INVALID), the slice data is invalid. It does not necessarily indicate that that slice has a hardware error.
For example, if an I/O error occurs on the copy source slice due to a hardware error during the synchronization copying of a mirror volume, data on the copy destination slice becomes invalid, but the copy source slice is still indicated as normal (active, stop, ACTIVE, or STOP). For details, see "F.1.1 Slice Status Abnormality."
