Remove volume from AdvanceDisk Pool

Hi Everyone,

I am running Netbackup 7.5.0.5 with one Master Server and one media server running windows 2008 R2 and running into issues removing a volume from a AdvanceDisk Pool. 

When trying to delete the volume with:

nbdevconfig -deletedv -stype AdvanceDisk -dp ADVPOOL_ACO_HQ -dv R:\

I get this error:

DSM was unable to find the following disk pool: ADVPOOL_HQ(AdvanceDisk)@XXXX-bk-hq1

I am not sure if it matters but that server ***-BK-HQ1 is my master server.

Any help would be great!
