Converting the dates from DataOnTap results?

GINOLARD99 — Thu, 05 Jun 2025 05:39:10 GMT

has anyone had any success parsing the dates returned from some DataOnTap cmdlets?

In particular, the LastOperationEnd date value returned from Get-NAVolSis which, annoyingly, returns a string value containing the Timezone info (e.g. CEST 2014) which .NET/Powerhsell doesn't handle at all well

edit: I notice some other cmdlets (get-NaSnapshot for example, return a proper datetime value). Why doesn't Get-NaSISVol do the same? This seems like a glaring inconsistency to me.

Matt -

Interesting... you can always created a custom object and redo it if you want, but why would we do that 🙂

What exactly do you need the system.datetime for in this cmdlet?

I'm writing a script to monitor certain things on our filers. One of the requirements is to check that the dedupe ran within the last 24 hours.

I've since found that I can use Get-NASis <volname> and that returns a DT formatted value (LastOperationEndTimestampDT). That's a proper datetime value which gives me what I want. It just seems strange that Get-NaSISVol (which, as far as I can tell does much the same thing as Get-NASis) returns a string value instead of datetime value.

Yes, interesting find, I never had the need to do that..

Once your done, if you don't mind sharing with the community

Sure. It's a bit rough but it does the job

        $Volumes=Get-NaVol
        ForEach ($volume in $Volumes)
        {
            $VolumeName=$volume.name
            $ASISInfo=Get-NASIS "/vol/$Volumename" -erroraction silentlycontinue

            If ($ASISInfo)
            {
                If ($AsisInfo.LastOperationState -ne "success")
                {
                    [string]$ASISError=$ASISInfo.LastOperationError
                    "ASIS last operation failed ($ASISError)"
                }

                $LastASISDate=$ASISInfo.LastOperationEndTimestampDT

                If ($LastASISDate)
                {
                    If ($LastASISDate -lt (Get-Date).AddHours(-24))
                    {
                        "lastasisdate is bad"
                    }
                }
            }
        }

Cool. are you dumping the information to a log and emailing you?

No it's being used in a script that sends information to our monitoring server. It'll flag the particular alert as red if the Dedupe didn't run in the last 24 hours.
