Hi

All hourly:

Import-Module DataONTAP
$CdotCred = Get-Credential
$clustersSessions = Connect-NcController 192.168.0.90 -HTTPS -Credential $CdotCred
$hourlysnap = Get-NcSnapshot -Volume "SAN1_vol1" -Controller $clustersSessions -SnapName "hourly.*"
$hourlysnap
$hourlysnap | Remove-NcSnapshot -Confirm

Oldest 3:

Import-Module DataONTAP
$CdotCred = Get-Credential
$clustersSessions = Connect-NcController 192.168.0.90 -HTTPS -Credential $CdotCred
$lastxsnap = Get-NcSnapshot -Volume "SAN1_vol1" -Controller $clustersSessions | sort Created -Descending | select -last 3
$lastxsnap
$lastxsnap | Remove-NcSnapshot -Confirm

If you just want to disable the creation of hourly snap on the cluster:

Cdot01::> vol show SAN1_vol1 -fields snapshot-policy
vserver volume    snapshot-policy
------- --------- ---------------
SAN1    SAN1_vol1 default
Cdot01::> snap policy show default
Vserver: Cdot01
                         Number of Is
Policy Name              Schedules Enabled Comment
------------------------ --------- ------- ----------------------------------
default                          3 true    Default policy with hourly, daily & w                                               eekly schedules.
    Schedule               Count     Prefix                 SnapMirror Label

Cdot01::> snap policy modify-schedule -policy default -schedule hourly -newcount 0                                             0

    Schedule               Count     Prefix                 SnapMirror Label
