[OpenIndiana-discuss] FC Target Offline when use unmap to release pool space in OI 151a.

[文军 戴]

Hello, I use openindiana 151a as my storage,and I found UnMap support in it, and I used it im my system.More description, I use Qlogic FC HBA as target. My client server is CentOS ,Linux localhost.localdomain 3.6.11 #1 SMP Sat Jan 5 14:00:14 CST 2013 x86_64 x86_64 x86_64 GNU/Linux, and use XFS as my filesystem. When I delete file from xfs system,and use sync to let unmap to execut, I encount a problem. My FC target is offline. And I must to cut down power to restart it. Does anyone know what happen? And I test 151a5, It is OK. qla2xxx [0000:04:00.0]-801c:0: Abort command issued nexus=0:0:0 --  1 2002.
