NBU appliance 5230

[rookie11]

we have old Netbackup appliance
Appliance Model is NetBackup Appliance 5230.
Appliance Version is 3.3.0.1.
When i checked on netbackup catalog it do not show any backup images on NBU appliance 5230. But disk pool it show 380 GB as used disk space
i checked via command line and found this
/dev/vx/dsk/nbuapp/pdvol 36T 237G 35T 1% /msdp/data/dp1/pdvol
/dev/vx/dsk/nbuapp/2pdvol 3.4T 19G 3.4T 1% /msdp/data/dp1/2pdvol
/dev/vx/dsk/nbuapp/1pdvol 36T 132G 35T 1% /msdp/data/dp1/1pdvol

How to be certain that it do not contain backup images before I decomm this NBU appliance

If nothing comes back, then the NetBackup catalog has no record of any images remaining on the Appliance and you're clear to proceed.
