Problem conclusion
Before IBM Spectrum Protect Plus level 10.1.15, when the opening of a VMware Virtual Machine Disk format (VMDK) disk hung indefinitely, the backup of the corresponding VM would wait until a timeout was reached by the backup job (typically two hours after the hang started). This would cause a VADP stream to be held by the stuck VM backup, starving other jobs of VADP streams and causing failure messages of the form, "There are no active storage streams all active vms are in initial stage or waiting for available streams." Since 10.1.15, a more localized timeout has been added to the VADP service, causing the disk open call to unblock within 10 minutes if the call hangs, freeing up the VADP stream much sooner and unblocking the backup of other VMs.
