问题描述

在多个磁盘同时出现故障后、丛失败
::> run -node <nodename> -command sysconfig -r 显示了故障磁盘
::> storage shelf drawer show -fields shelf,drawer,firmware-a,firmware-b,serial-number,part-number,vendor, fru-type,error,mfg-date 缺少某些故障磁盘的信息
::> storage shelf drawer show-phy 可能会显示 enabled enabled enabled-rate-unknown enabled-12gbs
某些驱动器可能会作为数据磁盘和备用磁盘进行恢复和恢复、但某些驱动器不会。
恢复后、仍会间歇性显示错误消息、但仅在受影响的抽盒上：

cluster-02: scsi_cmdblk_strthr_admin: scsi.cmd.abortedByHost:error]: Disk device 0c.12.14: Command aborted by host adapter: HA status 0x4: cdb 0x28:bd9d57d8:0008......................................

............................................................. [cluster-02: scsi_cmdblk_strthr_admin: scsi.cmd.retrySuccess:debug]: Disk device 4d.12.14: request successful after retry #1/#0: cdb 0x2f:04519800:0400 (8712).

事件日志中会显示另一个扩展器重置：
