using sssu to ungroup disk in background

[Demanez Denis]

Hello,

we have a EVA8000 (HSV210,XCS 6.220) and we have to remove a lot of disks.
I have tested the sssu command:

set DISK_GROUP delete="diskname"

There is no additional option to specify "ungroup in background".
When I launch this command, there is no more possibility to use the command view interface (http or sssu or RSM script) until the ungrouping is finished.

Is there any way to ungroup a disk via sssu in background?

Thank in advance,
Denis.
