bulk mgmt ip node change

You can change the IP address Orion uses to monitor a node by updating the "IP" property. In PowerShell, that looks like this:

$swis = Connect-Swis # your connection details here

$uri = 'swis://server/Orion/Orion.Nodes/NodeID=1'  # Get the node's Uri from somewhere, maybe a query

$newip = '10.1.2.3'  # get the new monitoring IP from somewhere

Set-SwisObject $swis $uri @{IP=$newip}

If you want to use Orion's data to find which IP address to use, you can query Orion.NodeIPAddresses to see what IPs a node has.

so .... will this work?

Add-PSSnapin SwisSnapin

Set-ExecutionPolicy RemoteSigned

$creds = Get-Credential

$swis = connect-swis -Credential $creds -Hostname host

swis1 = $swis

get-SwisData $swis "SELECT N.uri, I.IPAddress FROM Orion.NodeIPAddresses I 

INNER JOIN Orion.Nodes As N  on I.nodeid = N.nodeid

WHERE N.Caption like 'some%' AND I.IPAddress not like '5.5%''"

foreach ($node in $swis){

   Set-SwisObject $swis1 $node.uri @{IP=$node.IPAddress}

}

hmm ... this should be better code

Add-PSSnapin SwisSnapin

Set-ExecutionPolicy RemoteSigned

$creds = Get-Credential

$swis = connect-swis -Credential $creds -Hostname host

swis1 = $swis

$temp = get-SwisData $swis "SELECT N.uri, I.IPAddress FROM Orion.NodeIPAddresses I 

INNER JOIN Orion.Nodes As N  on I.nodeid = N.nodeid

WHERE N.Caption like 'some%' AND I.IPAddress not like '5.5%''"

foreach ($n in $temp){

   Set-SwisObject $swis1 $n.uri @{IP=$n.IPAddress}

}

That looks like it could work, but I would strongly recommend previewing the output of that query to make sure it is what you expect before committing the changes with the Set-SwisObject calls.
