HI all, new to the channel but have a question.

I'm trying to copy a snapshot to an existing vvol using the command "Copy-PfaSnapshotToExistingVvolvmdk". It works great 95% of the time. However we replicate data from one array to another, and I'm trying to do this on the secondary. 5% of the time the command fails with an error indicating that it can't do it because all of the data is not available yet. The worst part is that my entire PowerShell script stops executing when that happens, even when I wrap it in a Try/Catch block. My question is, does anyone know how to verify that a snapshot is 100% ready to use before I attempt to do the Copy-PfaSnapshotToExistingVvolvmdk command?

vmware

    i think replication needs to be checked at the source, dstamen do you know offhand?

    If it didn't do a hard break that killed the Powershell execution entirely I could at least handle the exception by selecting a different older snapshot. Unfortunately it's killing everything.

    We grab the last two snaps and check if it completed. If not we use the previous

    That's what I'm trying to do, but how do I "check if it completed"? If I use the copy command and the first one fails, the entire PS script stops executing like there's a hard break inside the command.
