Nimble thin LUN + CentOS 7: does discard / SCSI UNMAP work?
Hello,
I have Nimble CS700 running 5.0.4.0-576551-opt FW, I have a bucnh of thin LUNs that are iSCSI attached to CentOS 7 hosts , I recenetly noticed space consumuption mismatch of what being reported by those hosts and by the array.
OK, I found this document - https://infosight.hpe.com/InfoSight/media/kb/active/htr1455131720138.whz/mfu1456412605066.html and tried both methods decrived, however had no luck with it, and still see the space consumption mismatch, sometimes in TiB =(
Is there anyone who suscefully managed to setup Linux iSCSI initators, where "trim" utility worked?
Thanks!

This was actually the first thing I've done.
It's being hanlded as if HPE support doesn't care about it, they first pointed me the docs I already knew about, now it's been 2 weeks with no anwers whatsoever =(
