Humm!!
The choice for the pool on the "simultaneous write" is "none".
I see the note ... "During client node or import operations, data can be written to the primary storage pool and any combination of copy storage pools and active-data pools. " and your refering to the "ba" command
Which tend to lead me that I have my poll badly defined and I did not catch what the teach said:
Disk_os_pool (devclass = disk, type = primary random)
. >> next storage ... tape_os_pool ( devclass = lto, type = primary sequential))
. then I have ... tape_os_copy ( devclass = lto, type = copy)
my maintenance script script run ...
. mig stg diskpool du=90 lowmig=0
. ba stg tape_os_pool tape_os_copy
The option for migration have: du=85 low=50, so that I can restart backup's.
Moving my tape (using ba) to external media is fine. My issue is during backup session the disk fill soo fast that the "option for migration" does not free the disk and the pool storage taps to 100%, even dough I have migration going.
