Problem adding Data Volume - db_addvolume

Hello all,

My database is in the state 'Admin' due to Data Area Full;

I have tried to add a volume with db_addvolume but for this to work the database needs to be in 'Online' state.

I can turn the db to Offline or Admin; not to Online state.

I then changed the parameter to add an extra db file:

-> param_addvolume 5 DATA '/sapdb/AIO/sapdata/DISKD0005' F 3840000

but when I want to execute it:

-> util_execute ADD DATA VOLUME '/sapdb/AIO/sapdata/DISKD0005' PAGES 3840000 DEVICE 5

the db responds that it cannot have access to the file DISKD0005

I have then created the file manually:

-> touch DISKD0005

and repeated the operation but still no success.

Can you please help me get my db back Alive.

thank you

Youss
