如果此存储卷不是分布式设备的一部分,则主机将失去对此虚拟卷的访问权限,从而导致数据不可用的情况。

VPlex 固件日志描述了流式 scsi/27 事件和 SCSI 感知代码密钥 0xb asc 0x44 ascq 0x0 (B/44/00), 这会导致 内部目标故障

执行了 21 次重试,由于连续写入失败,存储卷被标记为无效。

Cause

存储阵列为写入 I/O 请求 (0x2a) 返回 B/44/00,阵列无法处理 I/O 请求,并使用检查条件 B/44/00(内部目标故障)进行响应

如果底层存储卷是 VMAX 卷,则可能会由于以下给出的原因而发生 I/O 故障:

VMAX 中止 IO 的原因未提供给 VPlex。发生内部目标故障的原因有很多,可能是由非常广泛的来源引起的。

 

Resolution

向 VPLEX 发送 scsi 检查条件 B/44/00 的存储阵列必须由相应的阵列供应商进行调查。此问题是由存储阵列上的“内部目标故障”问题导致阵列无法处理写入 I/O 请求触发的。

如果底层阵列是 VMAX 阵列,则阵列可以出于多种原因发送 scsi 检查条件“B/44/00”。

可以在 VPLEX 管理服务器上运行以下 cli 命令,以获取受 B/44/00 检查条件影响的逻辑单元列表:

grep "scsi/27" firmware.log* | grep 'key 0xb' |awk '{print $3, $5, $18, $19, $26,$27,$28,$29}'| sort | uniq -c | sort -nr

如果这是非 EMC 阵列,请联系相应的阵列供应商,以解决存储阵列上存在的问题。

 

Additional Information

这不是 VPlex 问题,这可能是后端阵列或结构问题。

必须联系存储阵列团队和/或连接。
