Re: [ovirt-users] Very big device. Trying to use READ CAPACITY

my os version is: Operating System: CentOS Linux 7 (Core) CPE OS Name: cpe:/o:centos:centos:7 Kernel: Linux 3.10.0-327.28.3.el7.x86_64 Architecture: x86-64 and san storage is EMC VNX 5400 with double cisco mds 9148s.

actually i had problem with one of my switches and sent it to garanty guarantee. now i set it up again ... . but i get these errors from dmesg: [20258845.245029] sd 12:0:0:16384: [sdf] Very big device.
