get-ncsnapmirror not working?

James_Castro — Wed, 04 Jun 2025 22:43:18 GMT

anyone else seeing this? am i missing something here? this should be pretty straight forward right?

Get-NcSnapmirror | Where-Object {$_.RelationshipType -eq "load_sharing"}

Get-NcSnapmirror : Object reference not set to an instance of an object.

+ Get-NcSnapmirror | Where-Object {$_.RelationshipType -eq "load_sharing"}

Another approach to this could be to have the cluster only reply with the load sharing mirrors by sumbitting the request with the query as shown below:

C:\PS>$query = Get-NcSnapmirror -Template
$query.RelationshipType = "load_sharing"
Get-NcSnapmirror -Query $query

Using an advanced query, get all load-sharing SnapMirror relationships.

-------------- ------------------- ------ -----------
VxeRubble://costea01/vol1_LS1 VxeRubble://costea01/vol1_LS2 idle snapmirrored

Example taken from the Toolkit Help file.

This is old method and imho, not prefered method, by building a template.. The OP, has the correct way in my mind..

I think I know what the issue is. The particular cluster I am runnin gthis on happens to be a very "busy" one. comand works fine on other less busy clusters. I believe the zapi is timing out even though i adjust the number of retries. Thanks
