add disk_domain disk

add disk_domain disk


add disk_domain disk command is used to add disks to a disk domain.


add disk_domain disk disk_domain_id=? disk_list=?

add disk_domain disk disk_domain_id=? disk_number=? disk_type=?





disk_domain_id=? ID of a disk domain to which you want to add disks.

To obtain the value, run "show disk_domain general".

disk_list=? ID list of disks that you want to add to a disk domain. If you specify this parameter, you cannot specify parameters disk_type=? and disk_number=?.

The value can be "all", disk ID range, or disk ID list, where:

  • "all": All free disks are added to a disk domain.
  • Disk ID range: The format is start disk ID-end disk ID, for example, DAE000.1-5.
  • Disk ID list: Multiple disk IDs are separated with commas (,), for example, DAE000.1,DAE000.2,DAE000.3.
To obtain the value, press "Ctrl+A" or run "show disk general".
disk_number=? Number of disks that you want to add to a disk domain. When you use this parameter with parameter disk_type=?, the system automatically adds disks of specified types and quantity to a disk domain. If you specify this parameter, you cannot specify parameter disk_list=?.

The value is an integer ranging from 1 to 2,147,483,647.

disk_type=? Type of a disk that you want to add to a disk domain.

The value can be "SAS", "NearLine_SAS", or "SSD", where:

  • "SAS": indicates serial attached SCSI (SAS) disks.
  • "NearLine_SAS": indicates near line SAS (NL-SAS) disks.
  • "SSD": indicates solid state drives (SSDs).
The following describes the disk type supported by each storage tier:
  • Tier 0 (high performance tier): SSD.
  • Tier 1 (performance tier): SAS disk.
  • Tier 2 (capacity tier): NL-SAS disk.



Usage Guidelines

If the number of added disks is smaller than the maximum number of disks for a RAID level that maps to storage pools in a disk domain, perform either of the following operations:

  • Create a LUN or expand LUN capacity after data is leveled in the disk domain.
  • If a thick LUN is created before data leveling is complete, start host services on the LUN after space allocation or formatting.


Add two SAS disks to disk domain "0".

admin:/>add disk_domain disk disk_domain_id=0 disk_number=2 disk_type=SAS
