ONTAP 中的少数FC LUN报告LUN错位

适用场景

• ONTAP 9
• FC
• VMware ESXi主机

问题描述

• 集群中LUN的LUN对齐显示为未对齐 

cx-xx-xx-aff::*> lun alignment show /vol/vol1/lun1
        Vserver Name: svm_name
          LUN Path: /vol/vol1/lun1
          OS Type: vmware
         Alignment: misaligned
Write Alignment Histogram: 82, 15, 0, 0, 0, 0, 0, 0
  Read Alignment Histogram: 82, 0, 0, 0, 0, 0, 3, 11
    Write Partial Blocks: 1
    Read partial Blocks: 3

• 此未对齐的LUN托管了3个VM、其中所有这3个VM都运行不同的子操作系统、如下所示
  • 1个Cisco ISE
  • 1个Power IQ
  • 1个VMware vCenter
