In the within-case hot spare mode, if a disk case totally becomes inaccessible due to an I/O cable coming out or disk case going down, a spare disk that belongs another disk case is not automatically connected. For example, if disk case 1 shown in [Figure 3.7 Hot Spare in Internal Mode] of "1.2.2 Hot Spare" is down, a spare disk (disk 4) is not automatically connected in place of disk 1.
In such an event, follow the procedures below to manually recover the mirroring status by using a spare disk.
Change the spare disk to an undefined disk.
