Editing a running VPG

    I’m trying to to use the reference to changing a VPG’s name in section 7 in “Automating Zerto Virtual Replication with PowerShell & REST APIs Whitepaper”

    I can call the POST VPGSettings with the appropriate body to convert a VPG to a VPGSettings.

    However, when I commit, I get a a 400 error

    Unknown web error: 400 : Bad Request

    All I’m doing is changing the name, and it appears that my PUT to VPGSettingsBasic works –

    VERBOSE: {
    "JournalHistoryInHours": 24,
    "Name": "ChrisLewisRocks",
    "Priority": 2,
    "ProtectedSiteIdentifier": "d492497e-6793-4ec8-b44b-f60a43aef445",
    "RecoverySiteIdentifier": "258fcb39-d6a3-4547-8797-3605da6d372b",
    "RpoInSeconds": 300,
    "ServiceProfileIdentifier": "",
    "TestIntervalInMinutes": 262080,
    "UseWanCompression": true,
    "ZorgIdentifier": ""
    }
    VERBOSE: PUT https://il1zerto.nuveen.com:9669/v1/vpgSettings/e94ec8a7-6d7e-4b13-a5d0-381f02a18f23/basic with -1-byte payload
    VERBOSE: received 0-byte response of content type

    And a subsequent GET on VPGSettings//Basic returns the new Basic section with the updated Name.

    POSTING with VPGSettings//commit fails.

    Hey Chris,

    Maybe its just a typo in pasting to the forum, but there appears to be a space in the URLs you are using: “https://il1zerto.nuveen.com :9669”. If you are just trying to change the name make sure you are just using the sample JSON and commands below:

    $JSON =
    “{
    “”Basic””: {
    “”Name””: “”$NewVPGName””
    }
    }”
    # Put URL & command
    $EditVPGURL = $BaseURL + “vpgsettings/” + $VPGSettingsIdentifier
    Try
    {
    $EditVPG = Invoke-RestMethod -Method PUT -Uri $EditVPGURL -Body $JSON -ContentType $TypeJSON -Headers $zertosessionHeader
    }
    Catch {
    Write-Host $_.Exception.ToString()
    $error[0] | Format-List -Force
    }
    # Committing the VPG setting
    $CommitVPGSettingURL = $BaseURL+”vpgSettings/”+”$VPGSettingsIdentifier”+”/commit”
    write-host “CommitVPGSettingURL:$CommitVPGSettingURL”
    Try
    {
    Invoke-RestMethod -Method Post -Uri $CommitVPGSettingURL -ContentType $TypeJSON -Headers $zertosessionHeader -TimeoutSec 100
    }
    Catch {
    Write-Host $_.Exception.ToString()
    $error[0] | Format-List -Force
    }

    If this is what you are using and still getting then try the same name change in the GUI first. It could be a duplicate name which is preventing the change. You can also go to ZVR in Program Files on the ZVM, logs, delete the latest log, re-run your commands, take a copy of the log, then look through it for “API” calls and you will get more information on why the commit is failing. Any further questions let me know. Thanks,

    Joshua

    Which is interesting since I’m not changing the Limit in MB – just the name.
