Parameters

Parameter

Description

Value

disk_domain_id=?

ID of a disk domain.

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

raid_level=?

RAID level.

The default value can be "RAID6-4", "RAID6-6", "RAID6-10", "RAID6-18", "RAID5-3", "RAID5-5", "RAID5-9", "RAID50-6", "RAID50-10", "RAID50-18", "RAID3-3", "RAID3-5", "RAID3-9", "RAID0", "RAID10", "RAID1-2", or "RAID1-4" and the non-default value can be "RAID3-N", "RAID5-N", or "RAID6-N", where:

  • "RAID6-4": indicates a RAID 6 group that contains four logical blocks (two data blocks and two parity blocks).
  • "RAID6-6": indicates a RAID 6 group that contains six logical blocks (four data blocks and two parity blocks).
  • "RAID6-10": indicates a RAID 6 group that contains ten logical blocks (eight data blocks and two parity blocks).
  • "RAID6-18": indicates a RAID 6 group that contains eighteen logical blocks (sixteen data blocks and two parity blocks).
  • "RAID5-3": indicates a RAID 5 group that contains three logical blocks (two data blocks and one parity block).
  • "RAID5-5": indicates a RAID 5 group that contains five logical blocks (four data blocks and one parity block).
  • "RAID5-9": indicates a RAID 5 group that contains nine logical blocks (eight data blocks and one parity block).
  • "RAID50-6": indicates a RAID 50 group that contains six logical blocks (four data blocks and two parity blocks).
  • "RAID50-10": indicates a RAID 50 group that contains ten logical blocks (eight data blocks and two parity blocks).
  • "RAID50-18": indicates a RAID 50 group that contains eighteen logical blocks (sixteen data blocks and two parity blocks).
  • "RAID3-3": indicates a RAID 3 group that contains three logical blocks (two data blocks and one parity block).
  • "RAID3-5": indicates a RAID 3 group that contains five logical blocks (four data blocks and one parity block).
  • "RAID3-9": indicates a RAID 3 group that contains nine logical blocks (eight data blocks and one parity block).
  • "RAID0": indicates a RAID 0 group whose number of logical blocks is automatically specified by the system.
  • "RAID10": indicates a RAID 10 group whose number of logical blocks is automatically specified by the system.
  • "RAID1-2": indicates a RAID 1 group that contains two logical blocks (the two logical blocks store the same data and mirror each other).
  • "RAID1-4": indicates a RAID 1 group that contains four logical blocks (the four logical blocks store the same data and mirror each other).
  • "RAID3-N": indicates a RAID 3 group that contains N logical blocks (N-1 data blocks and one parity block). N ranges from 3 to 14.
  • "RAID5-N": indicates a RAID 5 group that contains N logical blocks (N-1 data blocks and one parity block). N ranges from 3 to 14.
  • "RAID6-N": indicates a RAID 6 group that contains N logical blocks (N-2 data blocks and two parity blocks). N ranges from 4 to 28.
