HP EVA bug – Snapshot removed through sssu is still there

This is an interesting bug I have encountered:

The output of an sssu command should look like this:

EVA> DELETE STORAGE “Virtual DisksLinuxoracleSNAP_ORACLE”

EVA>

It still leaves the snapshot (SNAP_ORACLE in this case) visible, until the web interface is used to press on “Ok”.

This happened to me on HP EVA with HP StorageWorks Command View EVA 7.0 build 17.

When sequential delete command is given, it looks like this:

EVA> DELETE STORAGE “Virtual DisksLinuxoracleSNAP_ORACLE”

Error: Error cannot get object properties. [ Deletion completed]

EVA>

When this command is given for a non-existing snapshot, it looks like this:

EVA> DELETE STORAGE “Virtual DisksLinuxoracleSNAP_ORACLE”

Error: Virtual DisksLinuxoracleSNAP_ORACLE not found

So I run the removal command twice (scripted) on an sssu session without “halt_on_errors”. This removes the snapshots correctly.
