add disk_domain disk

add disk_domain disk


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


add disk_domain disk disk_domain_id=? disk_list=? [ ignore_disk_capacity=? ]

add disk_domain disk disk_domain_id=? disk_number=? disk_type=? [ ignore_disk_capacity=? ]





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 2147483647.

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

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

  • "SAS": indicates serial attached SCSI (SAS) disks.
  • "NearLine_SAS": indicates near line SAS (NL-SAS) disks.
  • "SSD": indicates solid state drives (SSDs).
  • "SAS_SED": indicates serial attached SCSI (SAS) self-encrypting disks.
  • "NearLine_SAS_SED": indicates near line SAS (NearLine_SAS) self-encrypting disks.
  • "SSD_SED": indicates solid state self-encrypting drives.
  • "SATA": Serial Advanced Technology Attachment(SATA) disks.
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.
ignore_disk_capacity=? Whether to ignore the disk capacity. This parameter is valid in the developer mode only. For details about how to log in to the developer mode, see the Restricted Command Reference.

The value can be "yes" or "no", where:

  • "yes":ignores the disk capacity.
  • "no":does not ignore the disk capacity. Check whether the capacity of expanded disks is truncated.



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, note the following items:

  • 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".
