问题描述

将Cisco Nexus 5000硬件更新到9000后、互联阵列与Nexus之间会出现CRC错误
SUSE SLES服务器定期发生FC中止和路径关闭、MPIO在path_checker"Tur"上挂起

示例：

Cisco：

Show interface fc1/x

X Discards, Y errors
 Z invalid CRC

ONTAP EMS：

fct_tpd_work_thread_0: scsitarget.ispfct.cttimeout:debug]: FC HBA nport  timed out while transmitting common transport frame of type 0x1 and command code GPPN

Linux：
