Doc Text:
After deleting the iscsi storage, ISCSIADM operations got stuck and wouldn't end.This caused connectStoragePool/GetDeviceList to fail on timeout. This has been fixed by removing forceIscsiScan() as iscsiadm already does that when refreshing sessions, and rewriting the logic with a simpler implementation.

Saggi,

It looks like the patch for iscsiadm will get into 6.5,
So we need to send a patch for VDSM to sdjust.
