标识 LUN
存在各种原因，导致您希望在计算主机上查找连接的存储卷的 LUN 标识。 例如，您可能有多个存储设备安装在具有相同卷大小的同一主机上。 您想要拆离并停用其中一个。 但是，您不确定如何将您在 Linux® 主机上看到的内容与控制台中看到的内容相关联。 另一个例子可能是，您有多个 Block Storage for Classic 卷附加到ESXi服务器上。 您想要扩展其中一个 LUN 的卷大小，并且需要知道要执行此操作的存储器的正确 LUN 标识。

接下来，使用 IBMCLOUD CLI 命令
ibmcloud sl block volume-list。 输出内容包括卷ID、存储设备的主机名、直流位置、存储类型、容量、已用空间量以及LUN ID。$ ibmcloud sl block volume-list id username datacenter storage_type capacity_gb bytes_used lunId 221426384 SL02SEL1160157-195 che01 endurance_block_storage 1500 - 2 332299016 SL02SEL1160157-220 dal13 endurance_block_storage 20 - 2 333280508 SL02SEL1160157-221 dal10 endurance_block_storage 200 - 0在此示例中，字符串 "333280508" 是卷标识，"0" 是 Block Storage for Classic LUN 的 LUN 标识。
发出命令
ibmcloud sl block volume-detail以获取有关存储卷的更多详细信息。$ ibmcloud sl block volume-detail 333280508 Name Value ID 333280508 User name SL02SEL1160157-221 Type endurance_block_storage Capacity (GB) 200 LUN Id 0 Endurance Tier READHEAVY_TIER Endurance Tier Per IOPS 2 Datacenter dal10 Target IP 161.26.99.155 # of Active Transactions 0 Replicant Count 0因此，您可以将 iscsi LUN 标识映射到块设备的主机名:
SL02SEL1160157-221 lun id: 0 Target IP: 161.26.99.155
在控制台中查看 LUN ID
您还可以收集 LUN ID、目标 IP 地址和主机名Block Storage for Classic控制台中的卷详情页面上的设备。
