Recommended actions:
•
Replace each failed disk with one of the same type (SSD, enterprise SAS, or midline SAS) and the same
or greater capacity. For continued optimum I/O performance, the replacement disk should have
performance that is the same as or better than the one it is replacing.
Configure disks as dedicated spares or global spares.
• For a dedicated spare, the disk must be of the same type as the other disks in the disk group and at
least as large as the smallest-capacity disk in the disk group, and it should have the same or better
performance.
• For a global spare, it is best to choose a disk that is as big as or bigger than the largest disk of its type
in the system and of equal or greater performance. If the system contains a mix of disk types (SSD,
enterprise SAS, or midline SAS), there should be at least one global spare of each type (unless
dedicated spares are used to protect every disk group of a given type).
Be sure to complete the trust procedure as documented in the CLI help for the trust command.
