Function New-UnityPool { <# .SYNOPSIS Creates a new storage pool. .DESCRIPTION Creates a new storage pool. Storage pools are the groups of disks on which you create storage resources. You need to have an active session with the array. .NOTES Written by Erwan Quelin under MIT licence - https://github.com/equelin/Unity-Powershell/blob/master/LICENSE .LINK https://github.com/equelin/Unity-Powershell .PARAMETER Session Specify an UnitySession Object. .PARAMETER Name Name of the pool. .PARAMETER Description Description of the pool. .PARAMETER virtualDisk Virtual Disks only with associated parameters to add to the pool. See examples for details. .PARAMETER raidGroup Parameters to add RAID groups to the pool (disk group, number of disks, RAID level, stripe length). See examples for details. .PARAMETER isFASTCacheEnabled Specify whether to enable FAST Cache on the storage pool. .PARAMETER isFASTVpScheduleEnabled Specify whether to enable scheduled data relocations for the pool. .PARAMETER alertThreshold For thin provisioning, specify the threshold, as a percentage, when the system will alert on the amount of subscription space used. .PARAMETER isHarvestEnabled Indicate whether the system should check the pool full high water mark for autodelete. .PARAMETER poolSpaceHarvestHighThreshold Specify the pool full high watermark for the storage pool. .PARAMETER poolSpaceHarvestLowThreshold Specify the pool full low watermark for the storage pool. .PARAMETER isSnapHarvestEnabled Indicate whether the system should check the snapshot space used high water mark for auto-delete. .PARAMETER snapSpaceHarvestHighThreshold Specify the snapshot space used high watermark to trigger auto-delete on the storage pool. .PARAMETER snapSpaceHarvestLowThreshold Specify the snapshot space used low watermark to trigger auto-delete on the storage pool. .EXAMPLE New-UnityPool -Name 'POOL01' -virtualDisk @{"id"='vdisk_1';"tier"='Performance'},@{"id"='vdisk_2';"tier"='Performance'} Create pool named 'POOL01' with virtual disks 'vdisk_1' and 'vdisk_2'. Virtual disks are assigned to the performance tier. Apply to Unity VSA only. .EXAMPLE New-UnityPool -Name 'POOL01' -raidGroup @{"id"='dg_11';"numDisks"= 15; 'raidType'='RAID5'; 'stripeWidth'='5'} Create pool named 'POOL01' with with 15 disks from diskgroup ID 'dg_11'.RAID protection is a 'RAID5' with a stripe width of 5 (4+1).
