[ADSM-L] TSM Database 83.5 % Full

["Yee, Julie Y." <Julie.Yee AT JHUAPL DOT EDU>]

I got this message from daily report. TSM Database 83.5 % full

Copy 1 on D:\database\db1.dsm           30 GB
Copy 2 on F:\database\dbcopydb1.dsm     30 GB

Copy 1 on D:\databased#######.dbv       7.5 GB
Copy 2 on F:\database\databased#######.dbv 7.5 GB 

q spacetrigger db f=d got the following output:
DB full Percentage:     90
DB space expansion percentage: 25
DB expansion prefix: d:\database
DB Maximum size (Megabytes): 0
Mirror prefix 1: f:\database
Mirror prefix 2:

Only  4 GB of space left on D drive.
 3.5 GB of space left on F drive.
How do I Extend DB ?? Do I need to define db volume first??

Please advice!
