Hi
can somebody help me to understand the UNMAP function on the flashsystem.
Or what i am doing wrong.
I want to use UNMAP for my hosts ( generic hosts Windows & AIX), i got spectrum virtualize 8.4.0.5. Flashsystem 7200 with all flash FCM2 modules.
I understand that UNMAP must be enable by default.
lssystem command shows that host_unmap is not enable
> lssystem
...
host_unmap off
...
So i enabled it:
> chsystem -hostunmap on
now lssystem shows it enabled.
For testing i type in a windows 2019 host:
PS:> defrag D: /L
but i got an error
"the operation requested is not supported by the hardware backing the volume"
same error with command. PS:> Optimize-volume
what am i doing wrong?
thank you in advance for any help
