NOTE
l For 18000 and 18000F series storage systems, the high hot spare policy is used by default.
You can only run the change disk_domain general command on the CLI to modify the hot
spare policy.
l When you are creating a disk domain, ensure that the disks used to provide hot spare space
are sufficient.
l Hot spare space can be used for the current disk domain only.
l Table 4-8 lists common capacity changes of the hot spare space. The number of disks
supported by a storage system and the capacity of their hot spare space are based on actual
specifications.
