问题描述

在查看ESXi的vmkernel.log时、您会看到一些事件、指示所有已挂载LUN的路径评估都近乎恒定：

2022-12-05T16:04:46.349Z cpu8:2099281)StorageDevice: 7059: End path evaluation for device naa.600a098038331464853abcd5635391234 2022-12-05T16:04:46.349Z cpu30:2099276)StorageDevice: 7059: End path evaluation for device naa.600a09803831464853abcd5635394567 2022-12-05T16:04:46.349Z cpu86:2099277)StorageDevice: 7059: End path evaluation for device naa.600a09803831464853abcd563539a789 2022-12-05T16:04:46.349Z cpu47:2099282)StorageDevice: 7059: End path evaluation for device naa.600a09803831464853abcd5635390123 2022-12-05T16:04:46.349Z cpu34:2099278)StorageDevice: 7059: End path evaluation for device naa.600a09803831464853abcd563539cdef

在 vobd 日志中，主机端出现“存储设备路径冗余”警报：

Path redundancy to storage device naa.600a0980xxxxxxxxxxxxxxxxxxx degraded. Path vmhba4:C0:T181:L26 is down. Affected datastores: xxx.

Path redundancy to storage device naa.600a0980xxxxxxxxxxxxxxxxxxx degraded. Path vmhba4:C0:T181:L24 is down. Affected datastores: xxx.

这些事件会频繁发生、并且会与失败的send key或维护key SCSI命令一起显示：

2022-12-05T22:10:15.259Z cpu50:2100588)VMW_SATP_ALUA: satp_alua_issueCommandOnPath:706: Path (vmhba64:C3:T1:L302) command 0xa3 failed with transient error status Transient storage condition, suggest retry. sense data: 0x6 0x3f 0xe. Waiting for 20 second$ 2022-12-05T22:10:15.259Z cpu50:2100588)VMW_SATP_ALUA: satp_alua_issueCommandOnPath:706: Path (vmhba64:C4:T0:L302) command 0xa3 failed with transient error status Transient storage condition, suggest retry. sense data: 0x6 0x3f 0xe. Waiting for 20 second$

请注意那些失败的SCSI命令的运行时ID：

vmhba64:C4:T0:L302

vmhba64:C3:T1:L302

在此示例中、对于LUN ID 302、ESXi尝试将SCSI命令问题描述到的目标为T0和T1。如果您检查LUN所使用的实际路径、则会看到目标ID 不同(T4)：

esxcfg-mpath -b
