If I want to set the aggregate raid-size,

What's the powershell command ?

set-ncaggr or ncaggroption ?

Hi Allen,

The -RaidSize parameter is set when creating the aggregate. Set "Get-Help Add-NcAggr" EG:

NAME New-NcAggr SYNOPSIS Create a new aggregate with the given name. SYNTAX New-NcAggr [-Name] <String> [-Node <String[]>] [-Striped] -DiskCount <Int32> [-DiskSize <Int64>] [-DiskType <String>] [-ChecksumStyle <String>] [-RaidSize <Int32>] [-ForceSparePool] [-BlockType <String>] [-AllowMixedRpm] [-IgnorePoolChecks] [-PreCheck] [-Mirrored] [-IncludeInAutobalance] [-AutobalanceState <String>] [-ForceSmallAggregate] [-Encrypt] [-Simulate] [-SnaplockType <String>] [-Controller <NcController[]>] [-RaidType <String>] [-InformationAction <ActionPreference>] [-InformationVariable <String>] [-PipelineVariable <String>] [-ZapiRetryCount <Int32>] [<CommonParameters>] New-NcAggr [-Name] <String> [-Node <String[]>] [-Striped] -DiskCount <Int32> [-DiskSize <Int64>] [-ChecksumStyle <String>] [-RaidSize <Int32>] [-ForceSparePool] [-BlockType <String>] [-AllowMixedRpm] [-IgnorePoolChecks] [-PreCheck] [-Mirrored] [-IncludeInAutobalance] [-AutobalanceState <String>] [-ForceSmallAggregate] [-Encrypt] [-DiskClass <String>] [-Simulate] [-SnaplockType <String>] [-Controller <NcController[]>] [-RaidType <String>] [-InformationAction <ActionPreference>] [-InformationVariable <String>] [-PipelineVariable <String>] [-ZapiRetryCount <Int32>] [<CommonParameters>] New-NcAggr [-Name] <String> [-Node <String[]>] [-Striped] -DiskCount <Int32> [-DiskSize <Int64>] [-ChecksumStyle <String>] [-RaidSize <Int32>] [-ForceSparePool] [-BlockType <String>] [-AllowMixedRpm] [-IgnorePoolChecks] [-PreCheck] [-Mirrored] [-IncludeInAutobalance] [-AutobalanceState <String>] [-ForceSmallAggregate] [-Encrypt] [-ActualDiskType <String>] [-Simulate] [-SnaplockType <String>] [-Controller <NcController[]>] [-RaidType <String>] [-InformationAction <ActionPreference>] [-InformationVariable <String>] [-PipelineVariable <String>] [-ZapiRetryCount <Int32>] [<CommonParameters>] New-NcAggr [-Name] <String> [-Node <String[]>] [-Striped] [-RPM <Int32>] [-RaidSize <Int32>] [-ForceSparePool] [-BlockType <String>] [-AllowMixedRpm] [-IgnorePoolChecks] [-PreCheck] [-Mirrored] [-IncludeInAutobalance] [-AutobalanceState <String>] [-ForceSmallAggregate] [-Encrypt] [-Simulate] [-SnaplockType <String>] [-Controller <NcController[]>] [-RaidType <String>] [-InformationAction <ActionPreference>] [-InformationVariable <String>] [-PipelineVariable <String>] [-ZapiRetryCount <Int32>] [<CommonParameters>] New-NcAggr [-Name] <String> [-Node <String[]>] [-Striped] -Disks <Object[]> [-MirrorDisks <Object[]>] [-RaidSize <Int32>] [-ForceSparePool] [-BlockType <String>] [-AllowSameCarrier] [-AllowMixedRpm] [-IgnorePoolChecks] [-PreCheck] [-Mirrored] [-IncludeInAutobalance] [-AutobalanceState <String>] [-ForceSmallAggregate] [-Encrypt] [-Simulate] [-SnaplockType <String>] [-Controller <NcController[]>] [-RaidType <String>] [-InformationAction <ActionPreference>] [-InformationVariable <String>] [-PipelineVariable <String>] [-ZapiRetryCount <Int32>] [<CommonParameters>] DESCRIPTION Create a new aggregate with the given name. Up to 200 aggregates can be created on each controller. The aggregate may not yet be operational immediately after the API returns.

Assuming you've added disks to expand the aggregate. EG

Set-NcAggrOption -Name aggr1_cluster1 -Key raidsize -Value 20

When it comes to creating aggregates, measure twice, cut once IMO
